FIELD OF THE INVENTION

The present invention concerns the use of a polypeptide having deoxyribonuclease (DNase) activity for preventing or reducing redeposition of soil on an item during a subsequent cleaning or laundering process. The invention further concerns a detergent composition comprising a polypeptide having deoxyribonuclease (DNase) activity and a method for preventing or reducing redeposition of soil on an item during a subsequent cleaning or laundering process.

BACKGROUND OF INVENTION

Microorganisms generally live attached to surfaces in many natural, industrial, and medical environments, encapsulated by extracellular substances including biopolymers and macromolecules. The resulting layer of slime encapsulated microorganism is termed a biofilm. Biofilms are the predominant mode of growth of bacteria in the natural environment, and bacteria growing in biofilms exhibit distinct physiological properties. Compared to their planktonically grown counterparts, the bacteria in a biofilm are more resistant to antibiotics, UV irradiation, detergents and the host immune response.

It has for many years been a known problem that laundry items like shirts and blouses become more and more grey as time goes by. For normal day clothing as well as sportswear sweat and the resulting odor is a challenge. These stains usually consist of a lot of different components adhering to the textile of the clothing and can be difficult to dissolve and remove. When laundry items like T-shirts or sportswear are used, they are contacted to sweat and bacteria from the body of the user and for other kinds of dirt from the rest of the environment in which they are used. Some of these bacteria are capable of adhering to the laundry item and form a biofilm on the item. The presence of bacteria implies that the laundry items become sticky and therefore soil adheres to the sticky areas. This soil has shown difficult to remove by commercially available detergent compositions. Further, when very dirty laundry items are washed together with less dirty laundry items the dirt present in the wash liquor tend to stick to the biofilm. As a result, the laundry item is more “soiled” and more greyed after washing than before washing.

Sportswear is a good example because there is often soil, clay and traffic dirt on the clothes washed together with very sweaty shirts. From wash to wash the clothes become greyer and greyer and they eventually appear as developed spots. This kind of dirt is one reason why people discard their clothes. Although the problem is well known in most garments the problem is very pronounced for mixed fabrics. There is a European political desire to conserve resources for laundry which has led to their adoption of a labeling law for washing machines in the EU to exclude machines with high energy consumption. This means that cold water washing is much more prevalent in the EU and thus come to resemble the rest of the world wash circumstances better. However, the saving of energy by washing at lower temperature may lead to consumers discarding clothes and buying new because the sweat stains are not properly removed. There is an urgent need to solve the problem of removing sweat stains effectively.

WO 2011/098579 concerns bacterial deoxyribonuclease compounds and methods for biofilm disruption and prevention.

Definitions

Alkyl: The term “alkyl” means a hydrocarbyl moiety which is straight or branched, saturated or unsaturated. Unless otherwise specified, alkyl moieties are preferably saturated or unsaturated with double bonds, preferably with one or two double bonds. Included in the term “alkyl” is the alkyl portion of acyl groups.

Automatic dishwashing composition: The term “automatic dishwashing composition” refers to compositions intended for cleaning dishware such as plates, cups, glasses, bowls, cutlery such as spoons, knives, forks, serving utensils, ceramics, plastics, metals, china, glass and acrylics in a dishwashing machine. The terms encompass any materials/compounds selected for domestic or industrial washing applications and the form of the product can be liquid, powder or granulate. In addition to lipase, the automatic dishwashing composition contains detergent components such as polymers, bleaching systems, bleach activators, bleach catalysts, silicates, dyestuff and metal care agents.

Allelic variant: The term “allelic variant” means any of two or more alternative forms of a gene occupying the same chromosomal locus. Allelic variation arises naturally through mutation, and may result in polymorphism within populations. Gene mutations can be silent (no change in the encoded polypeptide) or may encode polypeptides having altered amino acid sequences. An allelic variant of a polypeptide is a polypeptide encoded by an allelic variant of a gene.

Bacterial: In the context of the present invention, the term “bacterial” in relation to polypeptide (such as an enzyme, e.g., a DNAse) refers to a polypeptide encoded by and thus directly derivable from the genome of a bacteria, where such bacteria has not been genetically modified to encode said polypeptide, e.g., by introducing the encoding sequence in the genome by recombinant DNA technology. In the context of the present invention, the term “bacterial DNAse” or “polypeptide having DNAse activity obtained from a bacterial source” or “polypeptide is of bacterial origin” thus refers to a DNAse encoded by and thus directly derivable from the genome of a bacterial species, where the bacterial species has not been subjected to a genetic modification introducing recombinant DNA encoding said DNAse. Thus, the nucleotide sequence encoding the bacterial polypeptide having DNAse activity is a sequence naturally in the genetic background of a bacterial species. The bacterial polypeptide having DNAse activity encoding by such sequence may also be referred to a wildtype DNAse (or parent DNAse). In a further aspect, the invention provides provides polypeptides having DNase activity, wherein said polypeptides are substantially homologous to a bacterial DNase. In the context of the present invention, the term “substantially homologous” denotes a polypeptide having DNase activity which is at least 80%, preferably at least 85%, more preferably at least 90%, more preferably at least 95%, even more preferably at least 96%, 97%, 98%, and most preferably at least 99% identical to the amino acid sequence of a selected bacterial DNase.

Biofilm: A biofilm is any group of microorganisms in which cells stick to each other or stick to a surface, such as a textile, dishware or hard surface or another kind of surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS is a polymeric conglomeration generally composed of extracellular DNA, proteins, and polysaccharides. Biofilms may form on living or non-living surfaces. The microbial cells growing in a biofilm are physiologically distinct from planktonic cells of the same organism, which, by contrast, are single-cells that may float or swim in a liquid medium.

Bacteria living in a biofilm usually have significantly different properties from planktonic bacteria of the same species, as the dense and protected environment of the film allows them to cooperate and interact in various ways. One benefit of this environment for the microorganisms is increased resistance to detergents and antibiotics, as the dense extracellular matrix and the outer layer of cells protect the interior of the community.

On laundry, biofilm-producing bacteria can be found among the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis, and Stenotrophomonas sp. On hard surfaces, biofilm producing bacteria can be found among the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis, and Stenotrophomonas sp. In one embodiment the biofilm producing strain is Brevundimonas sp. In one embodiment the biofilm producing strain is Pseudomonas alcaliphila or Pseudomonas fluorescens.

cDNA: The term “cDNA” means a DNA molecule that can be prepared by reverse transcription from a mature, spliced, mRNA molecule obtained from a eukaryotic or prokaryotic cell. cDNA lacks intron sequences that may be present in the corresponding genomic DNA. The initial, primary RNA transcript is a precursor to mRNA that is processed through a series of steps, including splicing, before appearing as mature spliced mRNA.

Coding sequence: The term “coding sequence” means a polynucleotide, which directly specifies the amino acid sequence of a polypeptide. The boundaries of the coding sequence are generally determined by an open reading frame, which begins with a start codon such as ATG, GTG, or TTG and ends with a stop codon such as TAA, TAG, or TGA. The coding sequence may be a genomic DNA, cDNA, synthetic DNA, or a combination thereof.

Color difference (L value): A Lab color space is a color-opponent space with dimension L for lightness. L value, L* represents the darkest black at L*=0, and the brightest white at L*=100. In the context of the present invention L value is also referred to as color difference. The color difference method is used in the examples of the present patent application.

Control sequences: The term “control sequences” means nucleic acid sequences necessary for expression of a polynucleotide encoding a mature polypeptide of the present invention. Each control sequence may be native (i.e., from the same gene) or foreign (i.e., from a different gene) to the polynucleotide encoding the polypeptide or native or foreign to each other. Such control sequences include, but are not limited to, a leader, polyadenylation sequence, propeptide sequence, promoter, signal peptide sequence, and transcription terminator. As a minimum, the control sequences include a promoter, and transcriptional and translational stop signals. The control sequences may be provided with linkers for the purpose of introducing specific restriction sites facilitating ligation of the control sequences with the coding region of the polynucleotide encoding a polypeptide.

Enzyme Detergency benefit: The term “enzyme detergency benefit” is defined herein as the advantageous effect an enzyme may add to a detergent compared to the same detergent without the enzyme. Important detergency benefits which can be provided by enzymes are stain removal with no or very little visible soils after washing and/or cleaning, prevention or reduction of redeposition of soils released in the washing process (an effect that also is termed anti-redeposition), restoring fully or partly the whiteness of textiles which originally were white but after repeated use and wash have obtained a greyish or yellowish appearance (an effect that also is termed whitening). Textile care benefits, which are not directly related to catalytic stain removal or prevention of redeposition of soils, are also important for enzyme detergency benefits. Examples of such textile care benefits are prevention or reduction of dye transfer from one fabric to another fabric or another part of the same fabric (an effect that is also termed dye transfer inhibition or anti-backstaining), removal of protruding or broken fibers from a fabric surface to decrease pilling tendencies or remove already existing pills or fuzz (an effect that also is termed anti-pilling), improvement of the fabric-softness, colour clarification of the fabric and removal of particulate soils which are trapped in the fibers of the fabric or garment. Enzymatic bleaching is a further enzyme detergency benefit where the catalytic activity generally is used to catalyze the formation of bleaching components such as hydrogen peroxide or other peroxides.

Thus, the nucleotide sequence encoding the fungal polypeptide having DNAse activity is a sequence naturally in the genetic background of a fungal species. The fungal polypeptide having DNAse activity encoding by such sequence may also be referred to a wildtype DNAse (or parent DNAse). In a further aspect, the invention provides provides polypeptides having DNase activity, wherein said polypeptides are substantially homologous to a fungal DNase.

After one or more wash cycles, the textile is generally rinsed and dried.

Wash liquor: The term “wash liquor” is intended to mean the solution or mixture of water and detergents optionally including enzymes used for laundering textiles, for hard surface cleaning or for dishwashing.

DETAILED DESCRIPTION OF THE INVENTION

As described above, it has for many years been a known problem that laundry items like shirts and blouses loose whiteness or become more and more grey as time goes by. It is believed that part of this problem is due to redeposition of soil during washing so that when very dirty laundry items are washed together with less dirty laundry items the dirt present in the wash liquor tends to stick to the laundry items. As a result, the laundry item becomes more “soiled” and greyer after washing than it was before washing. The inventors have surprisingly found that the use of polypeptides having DNase activity can be used for preventing or reducing this redeposition of soil during a subsequent cleaning or laundering process. The item can be a textile or a hard surface, e.g., a dishware.

The inventors have found that when contacting an item such as a laundry item with a polypeptide having DNase activity, the laundry item is cleaner and less grey after a subsequent wash without DNase present than a similar laundry item, which has not been contacted with a polypeptide having DNase activity, see for examples examples 1 and 2. The inventors have found that a polypeptide having DNase activity can be used for maintaining or improving whiteness of the item, see for examples examples 1 and 2.

Further, the present invention concerns the use of a polypeptide having DNase activity for preventing or reducing adherence of soil and/or odour to an item during a subsequent cleaning or laundering process where no DNase is used, see examples 1-7.

The inventors have found that the use of a polypeptide having DNase activity can prevent or reduce malodour from an item such as textile (see Example 3 til 7) hard surfaces, e.g., dishware. In one embodiment of the invention the malodour is caused by E-2-nonenal.

In conventional laundry methods, the malodor may even survive the laundry process and the drying process. This has the effect that malodor can be sensed when the textile is used. This is not very pleasant for the user of the textile, i.e., when wearing sportswear that smells even before the sport activity has started. This can be embarrassing for the user of the textile who chooses to buy new sportswear instead of the bad smelling sportswear. By the use of the present invention this is avoided and the environment is thereby saved for use of limited resources such as raw material for new textiles, water, energy and pollution of the environment. In one embodiment of the invention the amount of E-2-nonenal present on a dry item after wash is prevented, reduced or removed.

One advantage of the present invention is that this malodor does not appear from the wet laundry items, i.e., when opening the washing machine. This makes the washing process a more attractive task both in domestic and industrial applications.

Another advantage of the present invention is that, when receiving the wet laundry directly from the washing machine or wash liquor, the laundry items do not have a malodor and are perceived as clean. Thereby time, money and energy for an unnecessary second or even third wash is saved. This is of huge advantage for the environment.

In one embodiment of the invention, the item is contacted with a polypeptide having DNase activity. The polypeptide having DNase activity can for example be sprayed onto the item. The deposition of soil and/or odour can thereby be reduced or removed by spraying the polypeptide onto for example carpets, floors or sheets.

Another way of preventing or reducing redeposition is contacting the item with a liquid solution comprising a polypeptide having DNase activity. The item can be contacted to the liquid solution for example by immersing the item into the liquid solution. The liquid solution can be a wash liquor and the item may be washed at the same time. This embodiment of the invention is preferred for textiles such as laundry textiles which can be washed at the same time. In one embodiment of the invention the textile is newly produced and is pretreated by wasing, immersing or impregnating the textile with the polypeptide having DNase activity after production of the textile. By impregnating the item, e.g., the textile the item may be more resistant to deposition of soil and/or odour on the item.

The wash liquor can also be used for washing floors or other hard surfaces which need anti-redeposition treatment.

The liquid solution can also be an impregnation liquid which liquid prevents the item from building up dirt during a subsequent cleaning or laundering process. The liquid solution for impregnation may serve as detergent and anti-redeposition solution at the same time

In one embodiment of the invention, the polypeptide having DNase activity is used for cleaning or laundering the item at least one time before the subsequent cleaning or laundering process, wherein the subsequent laundering process might not comprise the use of a DNase. In one embodiment, no polypeptide having DNase activity is used in the subsequent cleaning or laundering process.

In one embodiment, the polypeptide having DNase activity is used for cleaning or laundering the item at least two times, three times, four times, five times, six times, seven times, eight times, nine times or ten times before the subsequent cleaning or laundering process. In one embodiment, the polypeptide having DNase activity is used for cleaning or laundering the item at least two times, three times, four times, five times, six times, seven times, eight times, nine times or ten times before the subsequent cleaning or laundering process where no polypeptide having DNase activity is used.

The invention further concerns a detergent composition comprising a polypeptide having deoxyribonuclease (DNase) activity and a surfactant, wherein the composition fulfills at least one of a) or b):

The amount of the non-ionic surfactant is from about 0.2% to about 40% by weight of a nonionic surfactant, for example from about 0.5% to about 30%, in particular, from about 1% to about 20%, from about 3% to about 10%, such as from about 3% to about 5%, from about 8% to about 12%, or from about 10% to about 12%.

The surfactant can be a semipolar surfactant selected from the group consisting of amine oxides (AO) such as alkyldimethylamineoxide, N-(coco alkyl)-N,N-dimethylamine oxide and N-(tallow-alkyl)-N,N-bis(2-hydroxyethyl)amine oxide, and combinations thereof.

The present detergent composition can be used for preventing or reducing redeposition of soil on an item during a subsequent cleaning or laundering process and for preventing or reducing malodour.

The composition can further comprise builders, flocculating aid, chelating agents, dye transfer inhibitors, enzymes, enzyme stabilizers, enzyme inhinitors, catalytic materials, bleach activators, hydrogen peroxide, sources of hydrogen peroxide, preformed peracids, polymeric dispersing agents, clay soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, perfumes, structure elasticizing agents, fabric softeners, carriers, hydrotropes, builders and co-builders, fabric huing agents, anti-foaming agents, dispersants, processing aids, and/or pigments.

The composition may be a detergent composition suitable for laundering, dish washing or hard surface cleaning.

The invention further concerns a liquid detergent composition comprising a surfactant and a detergent and a detergent builder in a total concentration of at least 3% by weight, and a detergent enzyme containing microcapsule, wherein the membrane of the microcapsule is produced by cross-linking of a polybranched polyamine having a molecular weight of more than 1 kDa. The inventors have found, that encapsulating enzymes in a microcapsule with a semipermeable membrane, and having a water activity inside these capsules (prior to addition to the liquid detergent) higher than in the liquid detergent, the capsules will undergo a (partly) collapse when added to the detergent (water is oozing out), thus leaving a more concentrated and more viscous enzyme containing interior in the capsules. The collapse of the membrane may also result in a reduced permeability. This can be further utilized by addition of stabilizers/polymers, especially ones that are not permeable through the membrane. The collapse and resulting increase in viscosity will reduce/hinder the diffusion of hostile components (e.g., surfactants or sequestrants) into the capsules, and thus increase the storage stability of the enzyme in the liquid detergent. Components in the liquid detergent that are sensitive to the enzyme (e.g., components that act as substrate for the enzyme) are also protected against degradation by the enzyme. During wash the liquid detergent is diluted by water, thus increasing the water activity. Water will now diffuse into the capsules (osmosis). The capsules will swell and the membrane will either become permeable to the enzyme so they can leave the capsules, or simply burst and in this way releasing the enzyme. The concept is very efficient in stabilizing the enzymes against hostile components in liquid detergent, and vice versa also protects enzyme sensitive components in the liquid detergent from enzymes.

Examples of detergent components which are sensitive to, and can be degraded by, enzymes include (relevant enzyme in parenthesis): xanthan gum (xanthanase), polymers with ester bonds (lipase), hydrogenated castor oil (lipase), perfume (lipase), methyl ester sulfonate surfactants (lipase), cellulose and cellulose derivatives (e.g., CMC) (cellulase), and dextrin and cyclodextrin (amylase).

Sensitive detergent ingredients can also be encapsulated, and thus stabilized, in the microcapsules. Sensitive detergent ingredients are prone to degradation during storage. Such detergent ingredients include bleaching compounds, bleach activators, perfumes, polymers, builder, surfactants, etc.

Generally, the microcapsules can be used to separate incompatible components/compounds in detergents.

The addition of the microcapsules to detergents can be used to influence the visual appearance of the detergent product, such as an opacifying effect (small microcapsules) or an effect of distinctly visible particles (large microcapsules). The microcapsules may also be colored.

The microcapsules can be used to reduce the enzyme dust levels during handling and processing of enzyme products.

Unless otherwise indicated, all percentages are indicated as percent by weight (% w/w) throughout the application.

Microcapsule: The microcapsules are typically produced by forming water droplets into a continuum that is non-miscible with water—i.e., typically by preparing a water-in-oil emulsion—and subsequently formation of the membrane by interfacial polymerization via addition of a cross-linking agent. After eventual curing the capsules can be harvested and further rinsed and formulated by methods known in the art. The capsule formulation is subsequently added to the detergent.

The payload, the major membrane constituents and eventual additional component that are to be encapsulated are found in the water phase. In the continuum is found components that stabilize the water droplets towards coalescence (emulsifiers, emulsion stabilizers, surfactants etc.) and the cross linking agent is also added via the continuum.

The emulsion can be prepared be any methods known in the art, e.g., by mechanical agitation, dripping processes, membrane emulsification, microfluidics, sonication etc. In some cases simple mixing of the phases automatically will result in an emulsion, often referred to as self-emulsification. Using methods resulting in a narrow size distribution is an advantage.

The cross-linking agent(s) is typically subsequently added to the emulsion, either directly or more typically by preparing a solution of the crosslinking agent in a solvent which is soluble in the continuous phase. The emulsion and cross-linking agent or solution hereof can be mixed by conventional methods used in the art, e.g., by simple mixing or by carefully controlling the flows of the emulsion and the cross-linking agent solution through an in-line mixer.

In some cases, curing of the capsules is needed to complete the membrane formation. Curing is often simple stirring of the capsules for some time to allow the interfacial polymerization reaction to end. In other cases, the membrane formation can be stopped by addition of reaction quencher.

The capsules may be post modified, e.g., by reacting components onto the membrane to hinder or reduce flocculation of the particles in the detergent as described in WO 99/01534.

The produced capsules can be isolated or concentrated by methods known in the art, e.g., by filtration, centrifugation, distillation or decantation of the capsule dispersion.

The resulting capsules can be further formulated, e.g., by addition of surfactants to give the product the desired properties for storage, transport and later handling and addition to the detergent. Other microcapsule formulation agents include rheology modifiers, biocides (e.g., Proxel), acid/base for adjustment of pH (which will also adjust inside the microcapsules), and water for adjustment of water activity.

The capsule forming process may include the following steps:

- Preparation of the initial water and oil phase(s),
- Forming a water-in-oil emulsion,
- Membrane formation by interfacial polymerization,
- Optional post modification,
- Optional isolation and/or formulation,
- Addition to detergent.

The process can be either a batch process or a continuous or semi-continuous process.

A microcapsule according to the invention is a small aqueous sphere with a uniform membrane around it. The material inside the microcapsule is referred to as the core, internal phase, or fill, whereas the membrane is sometimes called a shell, coating, or wall. The microcapsules have diameters between 0.5 μm and 2 millimeters. Preferably, the mean diameter of the microcapsules is in the range of 1 μm to 1000 μm, more preferably in the range of 5 μm to 500 μm, even more preferably in the range of 10 μm to 500 μm, even more preferably in the range of 50 μm to 500 μm, and most preferably in the range of 50 μm to 200 μm. Alternatively, the diameter of the microcapsules is in the range of 0.5 μm to 30 μm; or in the range of 1 μm to 25 μm. The diameter of the microcapsule is measured in the oil phase after polymerization is complete. The diameter of the capsule may change depending on the water activity of the surrounding chemical environment.

Microencapsulation of enzymes, as used in the present invention, may be carried out by interfacial polymerization, wherein the two reactants in a polymerization reaction meet at an interface and react rapidly. The basis of this method is a reaction of a polyamine with an acid derivative, usually an acid halide, acting as a crosslinking agent. The polyamine is preferably substantially water-soluble (when in free base form). Under the right conditions, thin flexible membranes form rapidly at the interface. One way of carrying out the polymerization is to use an aqueous solution of the enzyme and the polyamine, which are emulsified with a non-aqueous solvent (and an emulsifier), and a solution containing the acid derivative is added. An alkaline agent may be present in the enzyme solution to neutralize the acid formed during the reaction. Polymer (polyamide) membranes form instantly at the interface of the emulsion droplets. The polymer membrane of the microcapsule is typically of a cationic nature, and thus bind/complex with compounds of an anionic nature.

The diameter of the microcapsules is determined by the size of the emulsion droplets, which is controlled, for example by the stirring rate.

Emulsion: An emulsion is a temporary or permanent dispersion of one liquid phase within a second liquid phase. The second liquid is generally referred to as the continuous phase. Surfactants are commonly used to aid in the formation and stabilization of emulsions. Not all surfactants are equally able to stabilize an emulsion. The type and amount of a surfactant needs to be selected for optimum emulsion utility especially with regard to preparation and physical stability of the emulsion, and stability during dilution and further processing. Physical stability refers to maintaining an emulsion in a dispersion form. Processes such as coalescence, aggregation, adsorption to container walls, sedimentation and creaming, are forms of physical instability, and should be avoided. Examples of suitable surfactants are described in WO 97/24177, pages 19-21; and in WO 99/01534.

Emulsions can be further classified as either simple emulsions, wherein the dispersed liquid phase is a simple homogeneous liquid, or a more complex emulsion, wherein the dispersed liquid phase is a heterogeneous combination of liquid or solid phases, such as a double emulsion or a multiple-emulsion. For example, a water-in-oil double emulsion or multiple emulsion may be formed wherein the water phase itself further contains an emulsified oil phase; this type of emulsion may be specified as an oil-in-water-in oil (o/w/o) emulsion. Alternatively, a water-in-oil emulsion may be formed wherein the water phase contains a dispersed solid phase often referred to as a suspension-emulsion. Other more complex emulsions can be described. Because of the inherent difficulty in describing such systems, the term emulsion is used to describe both simple and more complex emulsions without necessarily limiting the form of the emulsion or the type and number of phases present.

Polyamine: The rigidity/flexibility and permeability of the membrane is mainly influenced by the choice of polyamine. The polyamine according to the invention is a polybranched polyamine. Each branch, preferably ending with a primary amino group serves as a tethering point in the membrane network, thereby giving the favorable properties. A polybranched polyamine according to the present invention is a polyamine having more than two branching points and more than two reactive amino groups (capable of reacting with the crosslinking agent, i.e., primary and secondary amino groups). The polybranched polyamine is used as starting material when the emulsion is prepared—it is not formed in situ from other starting materials. To obtain the attractive properties, the polybranched structure of the polyamine must be present as starting material.

There is a close relation between number of branching points and number of primary amines, since primary amines will always be positioned at the end of a branch: A linear amine can only contain two primary amines. For each branching point hypothetically introduced in such a linear di-amine will allow one or more primary amine(s) to be introduced at the end of the introduced branch(es). In this context we understand the primary amino group as part of the branch, i.e., the endpoint of the branch. For example, we consider both tris(2-aminoethyl)amine and 1,2,3-propanetriamine as molecules having one branching point. For the invention the polyamine has at least four primary amines. Branching points can be introduced from an aliphatic hydrocarbon chain as in the previously stated examples or from unsaturated carbon bonds, such as in, e.g., 3,3′-diaminobenzidine, or from tertiary amino groups, such as in N,N,N′,N′-tetrakis-(2-aminoethyl)ethylenediamine.

In addition to the number of branching points, we have found that the compactness of the reactive amino groups is of high importance. A substance such as, e.g., N,N,N′,N′-tetrakis-(12-aminododecyl)ethylenediamine would not be suitable. Neither would a peptide or protein, such as an enzyme, be suitable for membrane formation. Thus, the polybranched polyamine is not a peptide or protein.

In an embodiment, the reactive amino groups constitute at least 15% of the molecular weight of the polybranched polyamine, such as more than 20%, or more than 25%. Preferably, the molecular weight of the polybranched polyamine is at least 1 kDa; more preferably, the molecular weight of the polybranched polyamine is at least 1.3 kDa.

In a preferred embodiment, the polybranched polyamine is a polyethyleneimine (PEI), and modifications thereof, having more than two branching points and more than two reactive amino groups; wherein the reactive amino groups constitute at least 15% of the molecular weight of the PEI, such as more than 20%, or more than 25%. Preferably, the molecular weight of the PEI is at least 1 kDa.

Combinations of different polybranched polyamines may be used for preparing the microcapsule according to the invention.

The advantageous properties (e.g., enzyme storage stability, reduced enzyme leakage, reduced in-flux of detergent ingredients) of the microcapsule may be improved by adding one or more small amines with a molecular weight of less than 1 kDa. The small amine is preferably substantially water-soluble (when in free base form) and can be a material such as ethylene diamine, hexamethylene diamine, hexane diamine, diethylene tetramine, ethylene tetramine, diamino benzene, piperazine, tetramethylene pentamine or, preferably, diethylene triamine (DETA). The small amines may be added in an amount of up to 50%, preferably up to 40%, up to 30%, up to 20%, up to 10%, or up to 5%, by weight of the total content of small amine and polybranched polyamine, when preparing the microcapsule.

Crosslinking agent: The crosslinking agent as used in the present invention is a molecule with at least two groups/sites capable of reacting with amines to form covalent bonds.

The crosslinking agent is preferably oil soluble and can be in the form of an acid anhydride or acid halide, preferably an acid chloride. For example, it can be adipoyl chloride, sebacoyl chloride, dodecanedioc acid chloride, phthaloyl chloride, terephthaloyl chloride, isophthaloyl chloride, or trimesoyl chloride; but preferably, the crosslinking agent is terephthaloyl chloride or trimesoyl chloride.

The polynucleotide of SEQ ID NO: 1 or SEQ ID NO: 4 or a subsequence thereof, as well as the polypeptide of SEQ ID NO: 5, SEQ ID NO: 2, SEQ ID NO: 3 or a fragment thereof, may be used to design nucleic acid probes to identify and clone DNA encoding polypeptides having DNase activity from strains of different genera or species according to methods well known in the art.

In particular, such probes can be used for hybridization with the genomic DNA or cDNA of a cell of interest, following standard Southern blotting procedures, in order to identify and isolate the corresponding gene therein. Such probes can be considerably shorter than the entire sequence, but should be at least 15, e.g., at least 25, at least 35, or at least 70 nucleotides in length. Preferably, the nucleic acid probe is at least 100 nucleotides in length, e.g., at least 200 nucleotides, at least 300 nucleotides, at least 400 nucleotides, at least 500 nucleotides, at least 600 nucleotides, at least 700 nucleotides, at least 800 nucleotides, or at least 900 nucleotides in length. Both DNA and RNA probes can be used. The probes are typically labeled for detecting the corresponding gene (for example, with ³²P, ³H, ³⁵S, biotin, or avidin). Such probes are encompassed by the present invention.

A genomic DNA or cDNA library prepared from such other strains may be screened for DNA that hybridizes with the probes described above and encodes a polypeptide having DNase activity. Genomic or other DNA from such other strains may be separated by agarose or polyacrylamide gel electrophoresis, or other separation techniques.

In another embodiment, the present invention relates to variants of the mature polypeptide of SEQ ID NO: 6 or SEQ ID NO: 7 comprising a substitution, deletion, and/or insertion at one or more (e.g., several) positions. In an embodiment, the number of amino acid substitutions, deletions and/or insertions introduced into the mature polypeptide of SEQ ID NO: 6 or SEQ ID NO: 7 is up to 10, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. The amino acid changes may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1-30 amino acids; small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain.

Examples of conservative substitutions are within the groups of basic amino acids (arginine, lysine and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine and valine), aromatic amino acids (phenylalanine, tryptophan and tyrosine), and small amino acids (glycine, alanine, serine, threonine and methionine). Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, In, The Proteins, Academic Press, New York. Common substitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr, Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile, Leu/Val, Ala/Glu, and Asp/Gly.

Alternatively, the amino acid changes are of such a nature that the physicochemical properties of the polypeptides are altered. For example, amino acid changes may improve the thermal stability of the polypeptide, alter the substrate specificity, change the pH optimum, and the like.

Essential amino acids in a polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081-1085). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for DNase activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., 1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide.

Single or multiple amino acid substitutions, deletions, and/or insertions can be made and tested using known methods of mutagenesis, recombination, and/or shuffling, followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241: 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA 86: 2152-2156; WO 95/17413; or WO 95/22625. Other methods that can be used include error-prone PCR, phage display (e.g., Lowman et al., 1991, Biochemistry 30: 10832-10837; U.S. Pat. No. 5,223,409; WO 92/06204), and region-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Ner et al., 1988, DNA 7: 127).

Mutagenesis/shuffling methods can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized polypeptides expressed by host cells (Ness et al., 1999, Nature Biotechnology 17: 893-896). Mutagenized DNA molecules that encode active polypeptides can be recovered from the host cells and rapidly sequenced using standard methods in the art. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide.

The polypeptide may be a hybrid polypeptide in which a region of one polypeptide is fused at the N-terminus or the C-terminus of a region of another polypeptide.

The polypeptide may be a fusion polypeptide or cleavable fusion polypeptide in which another polypeptide is fused at the N-terminus or the C-terminus of the polypeptide of the present invention. A fusion polypeptide is produced by fusing a polynucleotide encoding another polypeptide to a polynucleotide of the present invention. Techniques for producing fusion polypeptides are known in the art and include ligating the coding sequences encoding the polypeptides so that they are in frame and that expression of the fusion polypeptide is under control of the same promoter(s) and terminator. Fusion polypeptides may also be constructed using intein technology in which fusion polypeptides are created post-translationally (Cooper et al., 1993, EMBO J. 12: 2575-2583; Dawson et al., 1994, Science 266: 776-779).

A fusion polypeptide can further comprise a cleavage site between the two polypeptides. Upon secretion of the fusion protein, the site is cleaved releasing the two polypeptides. Examples of cleavage sites include, but are not limited to, the sites disclosed in Martin et al., 2003, J. Ind. Microbiol. Biotechnol. 3: 568-576; Svetina et al., 2000, J. Biotechnol. 76: 245-251; Rasmussen-Wilson et al., 1997, Appl. Environ. Microbiol. 63: 3488-3493; Ward et al., 1995, Biotechnology 13: 498-503; and Contreras et al., 1991, Biotechnology 9: 378-381; Eaton et al., 1986, Biochemistry 25: 505-512; Collins-Racie et al., 1995, Biotechnology 13: 982-987; Carter et al., 1989, Proteins: Structure, Function, and Genetics 6: 240-248; and Stevens, 2003, Drug Discovery World 4: 35-48.

Detergent Compositions

In one embodiment, the invention is directed to detergent compositions comprising an enzyme of the present invention in combination with one or more additional cleaning composition components. The choice of additional components is within the skill of the artisan and includes conventional ingredients, including the exemplary non-limiting components set forth below.

Odor Control Agents

Odor control agents are agents that reduces the malodour from an item, Odor control agents are agents that reduce, neutralize or remove malodor from an item when the odor control agent is used during washing or laundering of the item. The odor control agent is different from DNase.

Odor control agents of the present invention may include, but are not limited to HMP, volatile aldehydes or cyclodextrins or mixtures thereof.

In general, the present malodor-controlling compositions will comprise one or more odor control agent (s) at a level of from about 0.001% to about 99.99%, preferably from about 0.002% to about 99.9%, and more preferably from about 0.005% to about 99%, by weight of the malodor-controlling composition. When the compositions are aqueous liquid compositions (especially non-aerosol compositions) to be sprayed onto surfaces, such as fabrics, the compositions will preferably comprise less than about 20%, preferably less than about 10%, more preferably less than about 5%, by weight of the composition, of odor control agent. The odor control agent serves to reduce or remove malodor from the surfaces or objects being treated with the present compositions. The odor control agent is preferably selected from the group consisting of: uncomplexed cyclodextrin; odor blockers; reactive aldehydes; flavanoids; zeolites; activated carbon; and mixtures thereof.

Uncomplexed Cyclodextrin

As used herein, the term “uncomplexed cyclodextrin” includes any of the known cyclodextrins in uncomplexed form such as unsubstituted cyclodextrins containing from six to twelve glucose units, especially, alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin and/or their derivatives and/or mixtures thereof. The alpha-cyclodextrin consists of six glucose units, the beta-cyclodextrin consists of seven glucose units, and the gamma-cyclodextrin consists of eight glucose units arranged in donut-shaped rings. The specific coupling and conformation of the glucose units give the cyclodextrins a rigid, conical molecular structure with hollow interiors of specific volumes. The“lining” of each internal cavity is formed by hydrogen atoms and glycosidic bridging oxygen atoms; therefore, this surface is fairly hydrophobic. The unique shape and physical-chemical properties of the cavity enable the cyclodextrin molecules to absorb (form inclusion complexes with) organic molecules or parts of organic molecules which can fit into the cavity. Many odorous molecules can fit into the cavity including many malodorous molecules and perfume molecules. Therefore, cyclodextrins, and especially mixtures of cyclodextrins with different size cavities, can be used to control odors caused by a broad spectrum of organic odoriferous materials, which may, or may not, contain reactive functional groups. The complexation between cyclodextrin and odorous molecules occurs rapidly in the presence of water. However, the extent of the complex formation also depends on the polarity of the absorbed molecules. In an aqueous solution, strongly hydrophilic molecules (those which are highly water-soluble) are only partially absorbed, if at all. Therefore, cyclodextrin does not complex effectively with some very low molecular weight organic amines and acids when they are present at low levels on surfaces.

The cavities within the cyclodextrin in the deodorizing composition of the present invention should remain essentially unfilled (the cyclodextrin remains uncomplexed) while in solution, in order to allow the cyclodextrin to absorb various odor molecules when the solution is applied to a surface. Non-derivatised (normal) beta-cyclodextrin can be present at a level up to its solubility limit of about 1.85% (about 1.85 g in 100 grams of water) under the conditions of use at room temperature.

Preferably, the cyclodextrin used in the present invention is highly water-soluble such as, alpha-cyclodextrin and/or derivatives thereof, gamma-cyclodextrin and/or derivatives thereof, derivatised beta-cyclodextrins, and/or mixtures thereof. The derivatives of cyclodextrin consist mainly of molecules wherein some of the OH groups are converted to OR groups. Cyclodextrin derivatives include, e.g., those with short chain alkyl groups such as methylated cyclodextrins, and ethylated cyclodextrins, wherein R is a methyl or an ethyl group; those with hydroxyalkyl substituted groups, such as hydroxypropyl cyclodextrins and/or hydroxyethyl cyclodextrins, wherein R is a —CH₂—CH—(OH)—CH₃or a —CH₂CH₂—OH group; branched cyclodextrins such as maltose-bonded cyclodextrins; cationic cyclodextrins such as those containing 2-hydroxy-3-(dimethylamino) propyl ether, wherein R is CH₂—CH(OH)—CH₂—N—(CH₃)₂which is cationic at low pH; quaternary ammonium, e.g., 2-hydroxy-3-(trimethylammonio) propyl ether chloride groups, wherein R is CH₂—CH—(OH)—CH₂—N+(CH₃)₃Cl—; anionic cyclodextrins such as carboxymethyl cyclodextrins, cyclodextrin sulfates, and cyclodextrin succinylates; amphoteric cyclodextrins such as carboxymethyl/quaternary ammonium cyclodextrins; cyclodextrins wherein at least one glucopyranose unit has a 3-6-anhydro-cyclomalto structure, e.g., the mono-3-6-anhydrocyclodextrins, as disclosed in “Optimal Performances with Minimal Chemical Modification of Cyclodextrins”, F. Diedaini-Pilard and B. Perly, The 7th International Cyclodextrin Symposium Abstracts, April 1994, p. 49; and mixtures thereof. Other cyclodextrin derivatives are disclosed in U.S. Pat. No. 3,426,011, Parmerter et al., issued Feb. 4, 1969; U.S. Pat. Nos. 3,453,257; 3,453,258; 3,453,259; and 3,453,260, all in the names of Parmerter et al., and all issued Jul. 1, 1969; U.S. Pat. No. 3,459,731, Gramera et al., issued Aug. 5, 1969; U.S. Pat. No. 3,553,191, Parmerter et al., issued Jan. 5, 1971; U.S. Pat. No. 3,565,887, Parmerter et al., issued Feb. 23, 1971; U.S. Pat. No. 4,535,152, Szejtli et al., issued Aug. 13, 1985; U.S. Pat. No. 4,616,008, Hirai et al., issued Oct. 7, 1986; U.S. Pat. No. 4,678,598, Ogino et al., issued Jul. 7, 1987; U.S. Pat. No. 4,638,058, Brandt et al., issued Jan. 20, 1987; and U.S. Pat. No. 4,746,734, Tsuchiyama et al., issued May 24, 1988. Further cyclodextrin derivatives suitable herein include those disclosed in V. T. D'Souza and K. B. Lipkowitz, Chemical Reviews: Cyclodextrins, Vol. 98, No. 5 (American Chemical Society, July/August 1998).

Highly water-soluble cyclodextrins are those having water solubility of at least about 10 g in 100 ml of water at room temperature, preferably at least about 20 g in 100 ml of water, more preferably at least about 25 g in 100 ml of water at room temperature. Solubilized, water-soluble cyclodextrin can exhibit more efficient odor control performance than non-water-soluble cyclodextrin when deposited onto surfaces, especially carpeted surfaces.

Examples of preferred water-soluble cyclodextrin derivatives suitable for use herein are hydroxypropyl alpha-cyclodextrin, methylated alpha-cyclodextrin, methylated beta-cyclodextrin, hydroxyethyl beta-cyclodextrin, and hydroxypropyl beta-cyclodextrin. Hydroxyalkyl cyclodextrin derivatives preferably have a degree of substitution of from about 1 to about 14, more preferably from about 1.5 to about 7, wherein the total number of OR groups per cyclodextrin is defined as the degree of substitution. Methylated cyclodextrin derivatives typically have a degree of substitution of from about 1 to about 18, preferably from about 3 to about 16. A known methylated beta-cyclodextrin is heptakis-2, 6-di-O-methyl-cyclodexhin, commonly known as DIMEB, in which each glucose unit has about 2 methyl groups with a degree of substitution of about 14. A preferred, more commercially available, methylated beta-cyclodextrin is a randomly methylated beta-cyclodextrin, commonly known as RAMEB, having different degrees of substitution, normally of about 12.6. RAMEB is more preferred than DIMEB, since DIMEB affects the surface activity of the preferred surfactants more than RAMEB. The preferred cyclodextrins are available, e.g., from Cerestar USA, Inc. and Wacker Chemicals (USA), Inc.

It is also preferable to use a mixture of cyclodextrins. Such mixtures absorb odors more broadly by complexing with a wider range of odoriferous molecules having a wider range of molecular sizes. Preferably at least a portion of the cyclodextrin is alpha-cyclodextrin and its derivatives thereof, gamma-cyclodextrin and its derivatives thereof, and/or derivatised beta-cyclodextrin, more preferably a mixture of alpha-cyclodextrin, or an alpha-cyclodextrin derivative, and derivatised beta-cyclodextrin, even more preferably a mixture of derivatised alpha-cyclodextrin and derivatised beta-cyclodextrin, most preferably a mixture of hydroxypropyl alpha-cyclodextrin and hydroxypropyl beta-cyclodextrin, and/or a mixture of methylated alpha-cyclodextrin and methylated beta-cyclodextrin. Since cyclodextrin can be a prime breeding ground for certain microorganisms, especially when in aqueous compositions, it is preferable to include a water-soluble preservative, as described infra, which is effective for inhibiting and/or regulating microbial growth, to increase storage stability of aqueous odor-absorbing solutions containing water-soluble cyclodextrin.

Odor Blockers “Odor blockers” can be used as an odor control agent to mitigate the effects of malodors.

In order to be effective, the odor blockers normally have to be present at all times. If the odor blocker evaporates before the source of the odor is gone, it is less likely to control the odor. Also, the odor blockers can tend to adversely affect aesthetics by blocking desirable odors like perfumes.

Non-limiting examples of odor blockers suitable as odor control agents in the present compositions include 4-cyclohexyl-4-methyl-2-pentanone, 4-ethylcyclohexyl methyl ketone, 4-isopropylcyclohexyl methyl ketone, cyclohexyl methyl ketone, 3-methylcyclohexyl methyl ketone, 4-tert-butylcyclohexyl methyl ketone, 2-methyl-4-tert-butylcyclohexyl methyl ketone, 2-methyl-5-isopropylcyclohexyl methyl ketone, 4-methylcyclohexyl isopropyl ketone, 4-methylcyclohexyl sec-butyl ketone, 4-methylcyclohexyl isobutyl ketone, 2,4-dimethylcyclohexyl methyl ketone, 2,3-dimethylcyclohexyl methyl ketone, 2,2-dimethylcyclohexyl methyl ketone, 3,3-dimethylcyclohexyl methyl ketone, 4,4-di methylcyclohexyl methyl ketone, 3,3,5-trimethylcyclohexyl methyl ketone, 2,2,6-trimethylcyclohexyl methyl ketone, 1-cyclohexyl-1-ethyl formate, 1-cyclohexyl-1-ethyl acetate, 1-cyclohexyl-1-ethyl propionate, 1-cyclohexyl-1-ethyl isobutyrate, 1-cyclohexyl-1-ethyl n-butyrate, 1-cyclohexyl-1-propyl acetate, 1-cyclohexyl-1-propyl n-butyrate, 1-cyclohexyl-2-methyl-1-propyl acetate, 2-cyclohexyl-2-propyl acetate, 2-cyclohexyl-2-propyl propionate, 2-cyclohexyl-2-propyl isobutyrate, 2-cyclohexyl-2-propyl n-butyrate, 5,5-dimethyl-1,3-cyclohexanedione (dimedone), 2,2-dimethyl-1,3-dioxane-4,6-dione (Meldrum's acid), spiro-[4.5]-6,10-dioxa-7,9-dioxodecane, spiro-[5.5]-1,5-dioxa-2,4-dioxoundecane, 2,2-hydroxymethyl-1,3-dioxane-4,6-dione and 1,3-cyclohexadione. Odor blockers are disclosed in more detail in U.S. Pat. Nos. 4,009,253; 4,187,251; 4,719,105; 5,441,727; and 5,861,371.

Reactive Aldehydes

As an optional odor control agent, reactive aldehydes can be used as an odor control agent to mitigate the effects of malodors. Non-limiting examples of suitable reactive aldehydes include Class I aldehydes, Class II aldehydes, and mixtures thereof. Non-limiting examples of Class I aldehydes include anisic aldehyde, o-allyl-vanillin, benzaldehyde, cuminic aldehyde, ethyl-aubepin, ethyl-vanillin, heliotropin, tolyl aldehyde, and vanillin. Non-limiting examples of Class II aldehydes include 3-(4′-tert. butylphenyl) propanal, 2-methyl-3-(4′-tert-butylphenyl) propanal, 2-methyl-3-(4′-isopropylphenyl) propanal, 2, 2-dimethyl-3-(4-ethylphenyl) propanal, cinnamic aldehyde, a-amyl-cinnamic aldehyde, and a-hexyl-cinnamic aldehyde. These reactive aldehydes are described in more detail in U.S. Pat. No. 5,676,163.

Reactive aldehydes, when used, can include a combination of at least two aldehydes, with one aldehyde being selected from acyclic aliphatic aldehydes, non-terpenic aliphatic aldehydes, non-terpenic alicyclic aldehydes, terpenic aldehydes, aliphatic aldehydes substituted by an aromatic group and bifunctional aldehydes; and the second aldehyde being selected from aldehydes possessing an unsaturation alpha to the aldehyde function conjugated with an aromatic ring, and aldehydes in which the aldehyde group is on an aromatic ring. This combination of at least two aldehydes is described in more detail in WO 00/49120.

As used herein, the term “reactive aldehydes” further encompasses deodorizing materials that are the reaction products of (i) an aldehyde with an alcohol, (ii) a ketone with an alcohol, or (iii) an aldehyde with the same or different aldehydes. Such deodorizing materials can be: (a) an acetal or hemiacetal produced by means of reacting an aldehyde with a carbinol; (b) a ketal or hemiketal produced by means of reacting a ketone with a carbinol; (c) a cyclic triacetal or a mixed cyclic triacetal of at least two aldehydes, or a mixture of any of these acetals, hemiacetals, ketals, hemiketals, or cyclic triacetals. These deodorizing perfume materials are described in more detail in WO 01/07095.

Flavanoids

Flavanoids can also be used as an odor control agent. Flavanoids are compounds based on the Ca Q Q; flavan skeleton. Flavanoids can be found in typical essential oils. Such oils include essential oil extracted by dry distillation from needle leaf trees and grasses such as cedar, Japanese cypress, eucalyptus, Japanese red pine, dandelion, low striped bamboo and cranesbill and can contain terpenic material such as alpha-pinene, beta-pinene, myrcene, phencone and camphene. Also included are extracts from tea leaf. Descriptions of such materials can be found in JP 02284997 and JP 04030855.

Metallic Salts

The odor control agent of the present invention can include metallic salts for malodor control benefits. The metallic salts are selected from the group consisting of copper salts, zinc salts, and mixtures thereof.

The preferred zinc salts possess malodor control abilities. Zinc has been used most often for its ability to ameliorate malodor, e.g., in mouth wash products, as disclosed in U.S. Pat. Nos. 4,325,939 and 4,469,674. Highly-ionized and soluble zinc salts such as zinc chloride, provide the best source of zinc ions. Preferred zinc salts are selected from the group consisting of zinc borate, zinc caprylate, zinc chloride, zinc ricinoleate, zinc sulfate heptahydrate, zinc undecylenate, and mixtures thereof.

Preferably the metallic salts are water-soluble zinc salts, copper salts or mixtures thereof, and more preferably zinc salts, especially ZnCl₂. These salts are preferably present in the present invention as an odor control agent primarily to absorb amine and sulfur-containing compounds. Low molecular weight sulfur-containing materials, e.g., sulfide and mercaptans, are components of many types of malodors, e.g., food odors (garlic, onion), body/perspiration odor, breath odor, etc. Low molecular weight amines are also components of many malodors, e.g., food odors, body odors, urine, etc.

Zinc salts, when used, can be combined with an anionic surfactant having the formula R—(O—CH₂—CH₂)—X—O—CH₂COO—, wherein R is a fatty alcohol substituent or an alkylaryl substituent and X is at least 2. Such anionic surfactants can act as a control release agent for the zinc salts to improve the malodor control properties of the composition. This combination of zinc salts and anionic surfactant is described in more detail in U.S. Pat. No. 6,358,469.

Zinc salts, when used, can also be combined with carbonate and/or bicarbonate to improve the malodor control properties of the composition. When zinc salts are combined with carbonate and/or bicarbonate, the composition preferably further comprises a stabilizing anion selected from phosphates having more than one —(P═O)— group and organic acids having more than one acid functionality. This combination of zinc salts, carbonate and/or bicarbonate, and stabilizing anions is described in more detail in U.S. Pat. No. 6,015,547.

Copper salts possess some malodor control abilities. See U.S. Pat. No. 3,172,817, Leupold, et al., which discloses deodorizing compositions for treating disposable articles, comprising at least slightly water-soluble salts of acylacetone, including copper salts and zinc salts. When metallic salts are added to the composition of the present invention as an odor control agent, they are typically present at a level of from about 0.001% to an effective amount to provide a saturated salt solution, preferably from about 0.002% to about 25%, more preferably from about 0.003% to about 8%, still more preferably from about 0.1% to about 5% by weight of the composition.

Zeolites

The odor control agents herein can also be zeolites. A preferred class of zeolites is characterized as “intermediate” silicate/aluminate zeolites. The intermediate zeolites are characterized by SiOx/AlOz molar ratios of less than about 10. Preferably the molar ratio of SiO₂/AlO₂ranges from about 2 to about 10. The intermediate zeolites can have an advantage over the “high” zeolites. The intermediate zeolites have a higher affinity for amine-type odors, they are more weight efficient for odor absorption because they have a larger surface area, and they are more moisture tolerant and retain more of their odor absorbing capacity in water than the high zeolites. A wide variety of intermediate zeolites suitable for use herein are commercially available as Valfor® CP301-68, Valfor® 300-63, Valfor® CP300-35, and Valfor®CP300-56, available from PQ Corporation, and the CBV100® series of zeolites from Conteka.

Zeolite materials marketed under the trade name Absents® and Smellrite®, available from The Union Carbide Corporation and UOP are also preferred. Such materials are preferred over the intermediate zeolites for control of sulfur-containing odors, e.g., thiols, mercaptans. When zeolites are used as odor control agents in compositions that are to be sprayed onto surfaces, the zeolite material preferably has a particle size of less than about 10 microns and is present in the composition at a level of less than about 1% by weight of the composition.

Activated Carbon

Activated carbon is another suitable odor control agent for incorporation in the present compositions. The carbon material suitable for use in the present invention is the material well known in commercial practice as an absorbent for organic molecules and/or for air purification purposes. Often, such carbon material is referred to as“activated” carbon or“activated” charcoal.

Such carbon is available from commercial sources under such trade names as; Calgon-Type CPG®; Type PCB®; Type SGL®; Type CAL®; and Type OL®.

When activated carbon is used as an odor control agent in compositions that are to be sprayed onto surfaces, the activated carbon preferably has a particle size of less than about 10 microns and is present in the composition at a level of less than about 1% by weight of the composition.

To the extent any material described herein as an odor control agent might also be classified as another component described herein, for purposes of the present invention, such material shall be classified as an odor control agent.

Hydrophobically Modified Malodor Control Polymers (HMP)

The odor control agent can be a Hydrophobically Modified Malodor Control Polymers as described in WO 2012/097034.

The composition of the present invention includes a hydrophobically modified malodor control polymer (HMP). A HMP is formed from a polyamine polymer having a primary, secondary, and/or tertiary amine group that is modified with a hydrophobic group such as an alkyl, alkenyl, alkyloxide, or amide. Although the amine group has been modified, a HMP has at least one free and unmodified primary, secondary, and/or tertiary amine group, to react with malodorous components. Not wishing to be bound by theory, hydrophobic modification may increase a polymer's affinity for hydrophobic odors, thus enabling interactions between the odor molecules and active amine sites. In turn, HMPs may improve the breadth of malodor removal efficacy.

A HMP of the present invention has the general formula (I):

P(R)x (I)

wherein:

P is a polyamine polymer;

R is a C2 to C26 hydrophobic group; and

x is the total degree of substitution, which is less than 100%, of amine sites on the polymer.

1. Polyamine Polymers

HMPs may include a polyamine polymer backbone that can be either linear or cyclic. HMPs can also comprise polyamine branching chains. The polyamine polymer has a general formula (I1):

embedded image

where Q is an integer having values between 0-3.

Non-limiting examples of polyamine polymers include polyvinylamines (PVams), polyethyleneimines (PEIs) that are linear or branched, polyamidoamines (PAMams), polyallyamines (PAams), polyetheramines (PEams) or other nitrogen containing polymers, such as lysine, or mixtures of these nitrogen containing polymers.

a. PVams

In one embodiment, the HMP includes a PVam backbone. A PVam is a linear polymer with pendent, primary amine groups directly linked to the main chain of alternating carbons. PVams are manufactured from hydrolysis of poly(N-vinylformamide) (PVNF) which results in the con no groups as described by the following formula (I1a):

embedded image

where n is a number from 0.1 to 0.99 depending on the degree of hydrolysis. For instance, in 95% hydrolyzed PVam, n will be 0.95 while 5% of the polymer will have vinylformamide units. PVams may be partially hydrolyzed meaning that 1% to 99%, alternatively 30% to 99%, alternatively 50% to 99%, alternatively 70% to 99%, alternatively 80% to 99%, alternatively 85% to 99%, alternatively 90% to 99%, alternatively 95% to 99%, alternatively 97% to 99%, alternatively 99% of the PVam is hydrolyzed. It has been found that high degree of hydrolysis of PVam increases the resulting polymer's ability to mitigate the odors. PVams that can be hydrolyzed may have an average molecular weight (MW) of 5,000 to 350,000. Suitable hydrolyzed PVams are commercially available from BASF. Some examples include Lupamin™ 9095, 9030, 5095, and 1595.

Such hydrolyzed PVams may then be hydrophobically modified. Hydrophobic modification, as described below may further improve malodor removal efficacy,

b. Polyalkylenimine/PEIs

In another embodiment, the HMP includes a polyalkylenimine backbone. Polyalkylenimines include PEIs and polypropylenimines as well as the C4-C12 alkylenimines. PEI is a suitable polyalkylenimine. The chemical structure of a PEI follows a simple principle: one amine function and two carbons. PEIs have the following general formula (I1b):

—(CH₂—CH₂—NH)_n— (I1b):

where n=10-105

PEIs constitute a large family of water-soluble polyamines of varying molecular weight, structure, and degree of modification. They may act as weak bases and may exhibit a cationic character depending on the extent of protonation driven by pH.

PEIs are produced by the ring-opening cationic polymerization of ethyleneimine as shown below.

text missing or illegible when filed

PEIs are believed to be highly branched containing primary, secondary, and tertiary amine groups in the ratio of about 1:2:1. PEIs may comprise a primary amine range from about 30% to about 40%, alternatively from about 32% to about 38%, alternatively from about 34% to about 36%. PEIs may comprise a secondary amine range from about 30% to about 40%, alternatively from about 32% to about 38%, alternatively from about 34% to about 36%. PEIs may comprise a tertiary amine range from about 25% to about 35%, alternatively from about 27% to about 33%, alternatively from about 29% to about 31%.

Other routes of synthesis may lead to products with a modified branched chain structure or even to linear chain PEIs. Linear PEIs contain amine sites in the main chain while the branched PEIs contain amines on the main and side chains. Below is an example of a linear PEI

The composition of the present invention may comprise PEIs having a MW of about 800 to about 2,000,000, alternatively about 1,000 to about 2,000,000, alternatively about 1,200 to about 25,000, alternatively about 1,300 to about 25,000, alternatively about 2,000 to about 25,000, alternatively about 10,000 to about 2,000,000, alternatively about 25,000 to about 2,000,000, alternatively about 25,000.

In one embodiment, the PEI may have a specific gravity of 1.05 and/or an amine value of 18 (mmol/g, solid). For clarity, such specific gravity and/or amine value of the PEI describes the PEI before it is modified or added as part of an aqueous composition. One skilled in the art will appreciate, for example, the primary and secondary amino groups may react with other components of the composition.

Exemplary PEIs include those that are commercially available under the tradename Lupasol® from BASF or the tradename Epomine™ from Nippon Shokubia.

In some embodiments, less than 100% of the active amine sites are substituted with hydrophobic functional groups, alternatively about 0.5% to about 90%, alternatively about 0.5% to about 80%, alternatively about 0.5% to about 70%, alternatively about 0.5% to about 60%, alternatively about 0.5% to about 50%, alternatively about 0.5% to about 40%, alternatively about 0.5% to about 35%, alternatively about 0.5% to about 30%, alternatively about 1% to about 30%, alternatively about alternatively about 1% to about 25%, alternatively about 1% to about 20%, alternatively about 5% to about 20%, alternatively about 10% to about 30%, alternatively about 20% to about 30%, alternatively about 20% of the active amine sites are substituted with hydrophobic functional groups. When a PEI has active amine sites that are fully substituted with hydrophobic functional groups, such hydrophobically modified PEI may have no activity for malodor control.

where Q is an integer having values between 0-3 and V is a co-monomer.

Non-limiting examples of (I2) unmodified polymers include vinylamides, vinyl pyrrolidone, vinylimidazole, vinylesters, vinylalcohols, and mixtures thereof.

3. Hydrophobic Group

The hydrophobic group of the HMP may be linear, branched, or cyclic alkyl, hydroxyalkyl, alkenyl, hydroxyalkenyl, alkyl carboxyl, alkyloxide, alkanediyl, amide, or aryl. In some embodiments, the hydrophobic group is a C2 to C26, alternatively a C2 to C12, alternatively a C2 to 010, alternatively a C4 to 010, alternatively a C16 to C26, alternatively a C6. Where cyclodextrin is included in a formulation, it may be desirous to use a HMP that has been modified with a C2 to C10 alkyl group, alternatively a C16-C26 alkyl group, alternatively a C6 alkyl group, since such alkyl groups are cyclodextrin compatible.

4. Hydrophobic Modification

The polyamine backbones are hydrophobically modified in such a manner that at least one nitrogen, alternatively each nitrogen, of the polyamine chain is thereafter described in terms of a unit that is substituted, quaternized, oxidized, or combinations thereof.

There are many ways of hydrophobically modifying polyamine polymers. Generally, the modification is one directed to the primary, secondary, and/or tertiary amines of the polymer. By reacting the unmodified polyamine backbone with appropriate reagents, one can render the polyamine polymer hydrophobic, thereby increasing efficacy for malodor removal. The following are non-limiting examples of the ways to prepare the HMPs disclosed herein.

a. Alkoxylation

The reaction of polyamine polymer with an epoxide containing hydrocarbons (R) results in substitution of one or more nitrogen moities on the polymer.

wherein R>C2.

Non-limiting examples of such hydrocarbons include C2-C26 chains that are substituted or unsubstituted, branched or unbranched. For example, a reaction of dodeceneoxide with PEI polymer results in C6-HMP disclosed herein having a structure shown below.

Alternatively, one can modify the base polymer by reacting with EO first and then finish it by alkylation. Additional modifications might also include capping the modified polymer with EO groups if more water solubility is desired. Alternatively, hydroxyl groups can be substituted by further reacting the alkoxylated polymers as described in subparagraph c below.

b. Amidation

The reaction of polyamine polymers with amide-forming reagents such as anhydrides, lactones, isocyanates, or carboxylic acids results in substitution of one or more nitrogen moieties on the polymer rendering hydrophobic character. Prior to amidation, one can begin with partial substitution of amine sites with EO or PO and then carry out amidation on the remaining amine moieties. Reaction of anhydrides with polyamine polymers leads to the formation of amide units of the polymer by partial substitution of the primary/secondary amine sites. Non-limiting examples include non-cyclic carboxylic anhydrides such as acetic anhydride or cyclic carboxylic anhydrides such as maleic anhydride, succinic anhydride or phthalic anhydride. For example, the reaction of a polyamine with acetic anhydride introduces amide units onto the polymer.

wherein R>C2.

On the other hand, the reaction of polyamine polymer with cyclic anhydrides introduces amido acid units onto the polymer.

embedded image

More hydrophobically modified derivatives can be prepared by the use of cyclic anhydrides such as alkylene succinic anhydrides, dodecenyl succinic anhydride or polyisobutane succinic anhydride.

wherein R>C2.

Polyamine polymers containing hydroxyl-terminated polyamido units can be prepared by reacting the polymers with lactones. The use of more hydrophobic alkyl substituted lactones may introduce more hydrophobicity. Optionally, hydroxyl-end groups can be further substituted with functional groups as described in the subparagraph c below.

Isocyanate reactions with polyamine polymers result in the formation of urea derivatives shown below.

c. Alkoxylation Followed by Substitution of Hydroxyl Groups

Additional functional groups can be covalently bonded to an OH group on the alkoxylated polyamine polymers (“x” in formula (I)). This can be achieved by further reacting the alkoxylated polymers with bifunctional compounds such as epihalohydrins such as epichlorohydrin, 2-halo acid halides, isocyanataes or disocyanates such as trimethylhexane diisocyanate, or cyclic carboxylic anhydrides such as maleic anhydride or phthalic anhydride. For example, the reaction of alkoxylated PEI with isocyanates yields:

wherein R>C2.

All these HMPs disclosed herein can be optionally capped with hydrophilic groups, such as EO, to render water solubility if necessary.

In some embodiments, about 0.5% to about 90% of the amine groups on the entire unmodified polyamine polymer may be substituted with a hydrophobic group, alternatively about 0.5% to about 80%, alternatively about 0.5% to about 70%, alternatively about 0.5% to about 60%, alternatively about 0.5% to about 50%, alternatively about 0.5% to about 40%, alternatively about 0.5% to about 35%, alternatively about 0.5% to about 30%, alternatively about 1% to about 30%, alternatively about alternatively about 1% to about 25%, alternatively about 1% to about 20%, alternatively about 5% to about 20%, alternatively about 10% to about 30%, alternatively about 20% to about 30%, alternatively about 20% of the amine groups on the entire unmodified polyamine polymer may be substituted with a hydrophobic group. The level of substitution of the amine units can be as low as 0.01 mol percent of the theoretical maximum where all primary, secondary, and/or tertiary amine units have been replaced. HMPs for use herein may have a MW from about 150 to about 2*10⁶, alternatively from about 400 to about 10⁶, alternatively from about 5000 to about 10⁶.

Malodor control polymers suitable for use in the present invention are water-soluble or dispersible. In some embodiments, the primary, secondary, and/or tertiary amines of the polyamine chain are partially substituted rendering hydrophobicity while maintaining the desired water solubility. The minimum solubility index of a HMP may be about 2% (i.e., 2 g/100 ml of water). A suitable HMP for an aqueous fabric refresher formulation may have a water solubility percentage of greater than about 0.5% to 100%, alternatively greater than about 5%, alternatively greater than about 10%, alternatively greater than about 20%. The water solubility index can by determined by the Water Solubility test on page 13 of WO 2012/097034.

Volatile Aldehydes

The malodor control composition includes volatile aldehydes that neutralize malodors in vapor and/or liquid phase via chemical reactions. Aldehydes that are partially volatile may be considered a volatile aldehyde as used herein. Volatile aldehydes may react with amine-based odors, following the path of Schiff-base formation. Volatiles aldehydes may also react with sulfur-based odors, forming thiol acetals, hemi thiolacetals, and thiol esters in vapor and/or liquid phase. It may be desirable for these vapor and/or liquid phase volatile aldehydes to have virtually no negative impact on the desired perfume character of a product.

Suitable volatile aldehydes may have a vapor pressure (VP) in the range of about 0.0001 torr to 100 torr, alternatively about 0.0001 torr to about 10 torr, alternatively about 0.001 torr to about 50 torr, alternatively about 0.001 torr to about 20 torr, alternatively about 0.001 torr to about 0.100 torr, alternatively about 0.001 torr to 0.06 torr, alternatively about 0.001 torr to 0.03 torr, alternatively about 0.005 torr to about 20 torr, alternatively about 0.01 torr to about 20 torr, alternatively about 0.01 torr to about 15 torr, alternatively about 0.01 torr to about 10 torr, alternatively about 0.05 torr to about 10 torr, measured at 25° C. The volatile aldehydes may also have a certain boiling point (B.P.) and octanol/water partition coefficient (P). The B.P. referred to herein is measured under normal standard pressure of 760 mmHg. The B.P. of many volatile aldehydes, at standard 760 mm Hg are given in, for example, “Perfume and Flavor Chemicals (Aroma Chemicals),” written and published by Steffen Arctander, 1969.

The octanol/water partition coefficient of a volatile aldehyde is the ratio between its equilibrium concentrations in octanol and in water. The partition coefficients of the volatile aldehydes used in the malodor control composition may be more conveniently given in the form of their logarithm to the base 10, log P. The log P values of many volatile aldehydes have been reported. See, e.g., the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, Calif. However, the log P values are most conveniently calculated by the “C LOG P” program, also available from Daylight CIS. This program also lists experimental log P values when they are available in the Pomona92 database. The “calculated log P” (Clog P) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990). The fragment approach is based on the chemical structure of each volatile aldehyde and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. The Clog P values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental log P values in the selection of volatile aldehydes for the malodor control composition.

The Clog P values may be defined by four groups and the volatile aldehydes may be selected from one or more of these groups. The first group comprises volatile aldehydes that have a B.P. of about 250° C. or less and Clog P of about 3 or less. The second group comprises volatile aldehydes that have a B.P. of 250° C. or less and Clog P of 3.0 or more. The third group comprises volatile aldehydes that have a B.P. of 250° C. or more and Clog P of 3.0 or less. The fourth group comprises volatile aldehydes that have a B.P. of 250° C. or more and Clog P of 3.0 or more. The malodor control composition may comprise any combination of volatile aldehydes from one or more of the Clog P groups.

In some embodiments, the malodor control component may comprise, by weight of the malodor control component, from about 0% to about 30% of volatile aldehydes from group 1, alternatively about 25%; and/or about 0% to about 10% of volatile aldehydes from group 2, alternatively about 10%; and/or from about 10% to about 30% of volatile aldehydes from group 3, alternatively about 30%; and/or from about 35% to about 60% of volatile aldehydes from group 4, alternatively about 35%.

The amount of volatile aldehydes that may be formulated in the freshening composition may be from about 0.015% to about 1%, alternatively from about 0.01% to about 0.5%, alternatively, from about 0.015% to about 0.3%, by weight of the freshening composition.

In a particular embodiment, the detergent composition includes a mixture of one or more nonionic surfactants and one or more anionic surfactants. The surfactant(s) is typically present at a level of from about 0.1% to 60% by weight, such as about 1% to about 40%, or about 3% to about 20%, or about 3% to about 10%. The surfactant(s) is chosen based on the desired cleaning application, and may include any conventional surfactant(s) known in the art.

When included therein, the detergent will usually contain from about 1% to about 40% by weight of an anionic surfactant, such as from about 5% to about 30%, including from about 5% to about 15%, or from about 15% to about 20%, or from about 20% to about 25% of an anionic surfactant. Non-limiting examples of anionic surfactants include sulfates and sulfonates, in particular, linear alkylbenzenesulfonates (LAS), isomers of LAS, branched alkylbenzenesulfonates (BABS), phenylalkanesulfonates, alpha-olefinsulfonates (AOS), olefin sulfonates, alkene sulfonates, alkane-2,3-diylbis(sulfates), hydroxyalkanesulfonates and disulfonates, alkyl sulfates (AS) such as sodium dodecyl sulfate (SDS), fatty alcohol sulfates (FAS), primary alcohol sulfates (PAS), alcohol ethersulfates (AES or AEOS or FES, also known as alcohol ethoxysulfates or fatty alcohol ether sulfates), secondary alkanesulfonates (SAS), paraffin sulfonates (PS), ester sulfonates, sulfonated fatty acid glycerol esters, alpha-sulfo fatty acid methyl esters (alpha-SFMe or SES) including methyl ester sulfonate (MES), alkyl- or alkenylsuccinic acid, dodecenyl/tetradecenyl succinic acid (DTSA), fatty acid derivatives of amino acids, diesters and monoesters of sulfo-succinic acid or salt of fatty acids (soap), and combinations thereof.

Hydrotropes

A hydrotrope is a compound that solubilises hydrophobic compounds in aqueous solutions (or oppositely, polar substances in a non-polar environment). Typically, hydrotropes have both hydrophilic and a hydrophobic character (so-called amphiphilic properties as known from surfactants); however, the molecular structure of hydrotropes generally do not favor spontaneous self-aggregation, see, e.g., review by Hodgdon and Kaler, 2007, Current Opinion in Colloid & Interface Science 12: 121-128. Hydrotropes do not display a critical concentration above which self-aggregation occurs as found for surfactants and lipids forming miceller, lamellar or other well defined meso-phases. Instead, many hydrotropes show a continuous-type aggregation process where the sizes of aggregates grow as concentration increases. However, many hydrotropes alter the phase behavior, stability, and colloidal properties of systems containing substances of polar and non-polar character, including mixtures of water, oil, surfactants, and polymers. Hydrotropes are classically used across industries from pharma, personal care, food, to technical applications. Use of hydrotropes in detergent compositions allow for example more concentrated formulations of surfactants (as in the process of compacting liquid detergents by removing water) without inducing undesired phenomena such as phase separation or high viscosity.

The detergent may contain 0-10% by weight, for example 0-5% by weight, such as about 0.5 to about 5%, or about 3% to about 5%, of a hydrotrope. Any hydrotrope known in the art for use in detergents may be utilized. Non-limiting examples of hydrotropes include sodium benzenesulfonate, sodium p-toluene sulfonate (STS), sodium xylene sulfonate (SXS), sodium cumene sulfonate (SCS), sodium cymene sulfonate, amine oxides, alcohols and polyglycolethers, sodium hydroxynaphthoate, sodium hydroxynaphthalene sulfonate, sodium ethylhexyl sulfate, and combinations thereof.

Builders and Co-Builders

The detergent composition may contain about 0-65% by weight, such as about 5% to about 50% of a detergent builder or co-builder, or a mixture thereof. The builder and/or co-builder may particularly be a chelating agent that forms water-soluble complexes with Ca and Mg. Any builder and/or co-builder known in the art for use in detergents may be utilized. Non-limiting examples of builders include zeolites, diphosphates (pyrophosphates), triphosphates such as sodium triphosphate (STP or STPP), carbonates such as sodium carbonate, soluble silicates such as sodium metasilicate, layered silicates (e.g., SKS-6 from Hoechst), ethanolamines such as 2-aminoethan-1-ol (MEA), diethanolamine (DEA, also known as 2,2′-iminodiethan-1-ol), triethanolamine (TEA, also known as 2,2′,2″-nitrilotriethan-1-ol), and (carboxymethyl)inulin (CMI), and combinations thereof.

The detergent composition may also contain 0-50% by weight, such as about 5% to about 30%, of a detergent co-builder. The detergent composition may include include a co-builder alone, or in combination with a builder, for example a zeolite builder. Non-limiting examples of co-builders include homopolymers of polyacrylates or copolymers thereof, such as poly(acrylic acid) (PAA) or copoly(acrylic acid/maleic acid) (PAA/PMA). Further non-limiting examples include citrate, chelators such as aminocarboxylates, aminopolycarboxylates and phosphonates, and alkyl- or alkenylsuccinic acid.

The detergent may contain 0-30% by weight, such as about 1% to about 20%, of a bleaching system. Any bleaching system known in the art for use in detergents may be utilized. Suitable bleaching system components include bleaching catalysts, photobleaches, bleach activators, sources of hydrogen peroxide such as sodium percarbonate, sodium perborates and hydrogen peroxide-urea (1:1), preformed peracids and mixtures thereof. Suitable preformed peracids include, but are not limited to, peroxycarboxylic acids and salts, diperoxydicarboxylic acids, perimidic acids and salts, peroxymonosulfuric acids and salts, for example, Oxone (R), and mixtures thereof. Non-limiting examples of bleaching systems include peroxide-based bleaching systems, which may comprise, for example, an inorganic salt, including alkali metal salts such as sodium salts of perborate (usually mono- or tetra-hydrate), percarbonate, persulfate, perphosphate, persilicate salts, in combination with a peracid-forming bleach activator. The term bleach activator is meant herein as a compound which reacts with hydrogen peroxide to form a peracid via perhydrolysis. The peracid thus formed constitutes the activated bleach. Suitable bleach activators to be used herein include those belonging to the class of esters, amides, imides or anhydrides. Suitable examples are tetraacetylethylenediamine (TAED), sodium 4-[(3,5,5-trimethylhexanoyl)oxy]benzene-1-sulfonate (ISONOBS), 4-(dodecanoyloxy)benzene-1-sulfonate (LOBS), 4-(decanoyloxy)benzene-1-sulfonate, 4-(decanoyloxy)benzoate (DOBS or DOBA), 4-(nonanoyloxy)benzene-1-sulfonate (NOBS), and/or those disclosed in WO 98/17767. A particular family of bleach activators of interest was disclosed in EP 624154 and particularly preferred in that family is acetyl triethyl citrate (ATC). ATC or a short chain triglyceride like triacetin has the advantage that it is environmentally friendly. Furthermore, acetyl triethyl citrate and triacetin have good hydrolytical stability in the product upon storage and are efficient bleach activators. Finally, ATC is multifunctional, as the citrate released in the perhydrolysis reaction may function as a builder. Alternatively, the bleaching system may comprise peroxyacids of, for example, the amide, imide, or sulfone type. The bleaching system may also comprise peracids such as 6-(phthalimido)peroxyhexanoic acid (PAP). The bleaching system may also include a bleach catalyst. In some embodiments the bleach component may be an organic catalyst selected from the group consisting of organic catalysts having the following formula:

Wash Assays
Launder-O-Meter (LOM) Model Wash System

The Launder-O-Meter (LOM) is a medium scale model wash system that can be applied to test up to 20 different wash conditions simultaneously. A LOM is basically a large temperature controled water bath with 20 closed metal beakers rotating inside it. Each beaker constitutes one small washing machine and during an experiment, each will contain a solution of a specific detergent/enzyme system to be tested along with the soiled and unsoiled fabrics it is tested on. Mechanical stress is achieved by the beakers being rotated in the water bath and by including metal balls in the beaker.

The LOM model wash system is mainly used in medium scale testing of detergents and enzymes at European wash conditions. In a LOM experiment, factors such as the ballast to soil ratio and the fabric to wash liquor ratio can be varied. Therefore, the LOM provides the link between small scale experiments, such as AMSA and mini-wash, and the more time consuming full scale experiments in front loader washing machines.

Mini Launder-O-Meter (MiniLOM) Model Wash System

MiniLOM is a modified mini wash system of the Launder-O-Meter (LOM), which is a medium scale model wash system that can be applied to test up to 20 different wash conditions simultaneously. A LOM or is basically a large temperature controled water bath with 20 closed metal beakers rotating inside it. Each beaker constitutes one small washing machine and during an experiment, each will contain a solution of a specific detergent/enzyme system to be tested along with the soiled and unsoiled fabrics it is tested on. Mechanical stress is achieved by the beakers being rotated in the water bath and by including metal balls in the beaker.

In miniLOM, washes are performed in 50 ml test tubes placed in Stuart rotator.

Terg-O-Timeter (TOM) Wash Assay

The Tergo-To-Meter (TOM) is a medium scale model wash system that can be applied to test 12 different wash conditions simultaneously. A TOM is basically a large temperature controled water bath with up to 12 open metal beakers submerged into it. Each beaker constitutes one small top loader style washing machine and during an experiment, each of them will contain a solution of a specific detergent/enzyme system and the soiled and unsoiled fabrics its performance is tested on. Mechanical stress is achieved by a rotating stirring arm, which stirs the liquid within each beaker. Because the TOM beakers have no lid, it is possible to withdraw samples during a TOM experiment and assay for information on-line during wash.

The TOM model wash system is mainly used in medium scale testing of detergents and enzymes at US or LA/AP wash conditions. In a TOM experiment, factors such as the ballast to soil ratio and the fabric to wash liquor ratio can be varied. Therefore, the TOM provides the link between small scale experiments, such as AMSA and mini-wash, and the more time consuming full scale experiments in top loader washing machines.

Equipment: The water bath with 12 steel beakers and 1 rotating arm per beaker with capacity of 500 or 1200 mL of detergent solution. Temperature ranges from 5 to 80° C. The water bath has to be filled up with deionised water. Rotational speed can be set up to 70 to 120 rpm/min.

Set temperature in the Terg-O-Tometer and start the rotation in the water bath. Wait for the temperature to adjust (tolerance is +/−0.5° C.). All beakers shall be clean and without traces of prior test material.

The wash solution with desired amount of detergent, temperature and water hardness is prepared in a bucket. The detergent is allowed to dissolve during magnet stirring for 10 min. Wash solution shall be used within 30 to 60 min after preparation.

800 ml wash solution is added into a TOM beaker. The wash solution is agitated at 120 rpm and optionally one or more enzymes are added to the beaker. The swatches are sprinkled into the beaker and then the ballast load. Time measurement starts when the swatches and ballast are added to the beaker. The swatches are washed for 20 minutes after which agitation is terminated. The wash load is subsequently transferred from the TOM beaker to a sieve and rinse with cold tap water. The soid swatches are separated from the ballast load. The soil swatches are transferred to a 5 L beaker with cold tap water under running water for 5 minuttes. The ballast load is kept separately for the coming inactivation. The water is gently pressed out of the swatches by hand and placed on a tray covered with a paper. Another paper is palced on top of the swatches. The swatches are allowed to dry overnight before subjecting the swatches to analysis, such as assaying for odor removal as described in Example 7.

Full Scale Wash

This is the test method used to test the wash performance of DNAse in full scale wash under EU conditions (washing in a front loader washing machine).

The real items (T-shirts) and ballast are added to each wash together with detergent and enzyme. After wash, the real items (T-shirts) are dried. After drying, round swatches are cut out and washed with detergent added soil (dirty detergent) in miniLOM. Color difference is measured on a MacBeth Color Eye spectrophotometer.

The enzymes are added on basis of weight percent of the detergent dosage in each wash.

Equipment Used:

- Washing machine: Miele Softtronic W2445
- Water meters and automatically data collection system
- MacBeth Color Eye spectrophotometer

For the Preparation and Adjustment of Water Hardness the Following Ingredients are Needed:

- Calcium chloride (CaCl₂.2H₂O)
- Chloride (MgCL₂.6H₂O)
- Sodium Hydrogen Carbonate (NaHCO₃)

Ballast

The ballast consists of clean white cloth without optical whitener made of cotton, polyester or cotton/polyester. The composition of the ballast is a mix of different items at a cotton/polyester ratio of 65/35 based on weight. The ballast weight, dryness and item composition must be the same in each wash.

After each wash the ballast is inactivated in an industrial washer at 85° C./15 min or in a 95° C. wash (EU machine) without detergent

Ballast Example: (Standard EU ballast composition, total 3 kg)

- 3 T-shirts (100% cotton)
- 10 shirts, short sleeves (55% cotton 45% polyester)
- 4 pillow cases (35% cotton, 65% polyester), 110×75 cm
- 1 small bed sheets, size 100×75 cm (100% cotton)
- 3 Tea towels (100% cotton)
- Socks (80% cotton 20% polyester) as balance

Wash Conditions

- Temperature: 30° C.
- Washing programme: Normal cotton wash without pre-wash: “Cottons”
- Water level 13-14 L with “water plus”
- Water hardness: Standard EU conditions: 15° dH, Ca²⁺:Mg²⁺:HCO₃=4:1:7.5
- DNAse dosage: 1 ppm.

Detailed Steps to Carry Out Full Scale Wash Trial

1. Select wash program as in study plan.

2. The detergent and DNAse are placed in the wash drum in a “washing ball” (both liquid and powder detergents). Place it at the bottom.

3. Place the real items (T-shirts) and ballast in the wash drum.

4. Start digital water meter

5. Start the washer by pressing the knob START

6. After wash, take out real items (T-shirts) and ballast, put real items into drying room.

Drying Procedure

Put stains on tray or hang in line and dry at room temperature. The room has a de-humidifier working for 24 hours per day to keep the room dry

Measurement

Round swatches from T-shirts (armpits, front, back and edge) are cut out and washed in miniLOM with dirty detergent added soil. Swatches are evaluated by measurement of Color difference (L values) was measured using a Color Eye (Macbeth Color Eye 7000 reflectance spectrophotometer). The measurements were made without UV in the incident light, and the L value from the CIE Lab color space was extracted.

Enzyme Assays
Assay I
Testing of DNase Activity

DNase activity was determined on DNase Test Agar with Methyl Green (BD, Franklin Lakes, N.J., US), which was prepared according to the manual from supplier. Briefly, 21 g of agar was dissolved in 500 ml water and then autoclaved for 15 min at 121° C. Autoclaved agar was temperated to 48° C. in water bath, and 20 ml of agar was poured into petridishes with and allowed to solidify by incubation o/n at room temperature. On solidified agar plates, 5 μl of enzyme solutions are added, and DNase activity are observed as colorless zones around the spotted enzyme solutions.

Assay II
Analysis of E-2-Nonenal on Textile Using an Electronic Nose

One way of testing for the presence of malodor on textiles is by using E-2-Nonenal as a marker for the malodor, as this compound contributes to the malodor on laundry.

Add a solution of E-2-nonenal to a 5 cm×5 cm textile swatch and place the swatch in a 20 mL glass vial for GC analysis and cap the vial. Analyze 5 mL headspace from the capped vials in a Heracles II Electronic nose from Alpha M.O.S., France (double column gas chromatograph with 2 FIDs, column 1: MXTS and column 2: MXT1701) after 20 minutes incubation at 40° C.

EXAMPLES
Example 1
Detection of Deep-Cleaning Effects on T-Shirts for Running

Two white T-shirts for running made of 100% polyester were washed (full scale wash) in a washing machine using 3.33 g/L of model detergent A.

The two T-shirts were worn by a test person (male), one T-shirt at the time. The test person wore each of the the T-shirts during physical activity for one hour. After wearing, one T-shirt was washed in a washing machine using 3.33 g/L of model detergent A with the DNAse of SEQ ID NO: 7 (1 ppm), whereas the second T-shirt was washed in a washing machine using 3.33 g/L of model detergent A without the DNAse (0 ppm). The T-shirts were washed as described in the full scale wash described above and for washing, 15 L of tap water was used. Both T-shirts were worn during physical activity and then washed. This wear and wash cycle was repeated 10 times.

For evaluation of the cleaning effect (deep-cleaning effect), five circular swatches (diameter of 2 cm) were cut out from armpit, back (upper back, between shoulders), front (breast) and lower front edge of the T-shirts. Five swatches from armpit, back, front and edge, respectively were mixed with five sterile Polyester WFK30A swatches in a 50 mL test tube and added 10 mL of wash liquor prepared by adding 3.33 g/I in water of a model detergent A added 0.7 g/L soil (Pigmentschmutz, 09V, wfk, Krefeld, Germany). Test tubes were placed in a Stuart rotator (miniLOM) for 1 hour at 30° C. and washed in accordance with the miniLOM described above. Swatches were rinsed twice with 10 ml of tap water and dried on filter paper over night.

Color difference (L value) was measured using a Color Eye (Macbeth Color Eye 7000 reflectance spectrophotometer). The measurements were made without UV in the incident light, and the L value from the CIE Lab color space was extracted. A high L value reflects a white textile. Thus, the higher ΔL, the whiter textile.

The result below shows that washing with DNase during 10 washes prevents deposition of soil in a subsequent laundering process. In addition, the results show that washing with DNase during 10 washes improves the whiteness of the textile.

Example 2
Deep-Cleaning Performance of DNAse in Liquid Detergent Over 2 Washes

One strain of Brevundimonas sp. isolated from laundry was used in the present example. Brevundimonas sp. was pre-grown on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131; Oxoid Ltd, Basingstoke, UK) for 2-5 days at 30° C. From a single colony, a loop-full was transferred to 10 mL of TSB (Tryptone Soya broth, Oxoid) and incubated for 16 hours at 30° C. with shaking (240 rpm). After propagation, Brevundimonas sp. was pelleted by centrifugation (Sigma Laboratory Centrifuge 6K15) (3000 g at 21° C. in 7 min) and resuspended in 10 mL of TSB diluted twice with milliQ water. Optical density (OD) at 600 nm was measured using a spectrophotometer (POLARstar Omega (BMG Labtech, Ortenberg, Germany). Fresh TSB diluted twice with sterile milliQ water was inoculated with Brevundimonas sp. to OD_600nm0.03, and 1.6 mL was added into each well of a 12-well polystyrene flat-bottom microplate (3512; Corning Incorporated, Corning, N.Y., USA), in which round swatches (diameter 2 cm) of sterile Polyester WFK30A was placed. After 24 h and 72 h incubation, respectively, at 15° C. with shaking (100 rpm), growth media was removed, and swatches were rinsed twice with 0.9% (w/v) NaCl.

In wash 1, five rinsed swatches with Brevundimonas sp. as prepared above (donor swatches) were mixed with five sterile Polyester WFK30A swatches (tracer swatches) in a 50 mL test tube and added 10 mL of wash liquor prepared by adding 3.33 g/I in water of a model detergent A and DNAse of SEQ ID NO: 2 (0.04 ppm). Washes with model detergent A without DNAse added were made in parallel. Test tubes were placed in a Stuart rotator (miniLOM) for 1 hour at 30° C. and washed in accordance with the miniLOM described above. Swatches were rinsed twice with tap water and dried on filter paper over night.

In wash 2, the five dried donor and tracer swatches from wash 1 were washed in a 50 mL test tube added 10 mL of wash liquor prepared by adding 3.33 g/I in water of a model detergent A and 0.7 g/L soil (Pigmentschmutz, 09V, wfk, Krefeld, Germany). Test tubes were placed in a Stuart rotator for 1 hour at 30° C. and washed in accordance with the miniLOM described above. Swatches were rinsed twice with tap water and dried on filter paper over night.

Color difference (L values) was measured using a Color Eye (Macbeth Color Eye 7000 reflectance spectrophotometer). The measurements were made without UV in the incident light, and the L value from the CIE Lab color space was extracted. A high L value reflects a white textile. Thus, the higher ΔL, the whiter textile.

The results in the table below shows that the L-values measured after wash 2. The results show that washing with DNase in wash 1 prevents deposition of soil in a subsequent laundering process with no DNase present. In addition, the results show that washing with DNase during 10 washes improves the whiteness of the textile.

Detection of Sweaty Odor on T-Shirts for Running

Two white T-shirts for running made of 100% polyester were washed in a washing machine (full scale wash) using 3.33 g/L of model detergent A.

For evaluation of odor, a trained test person investigated T-shirts prior to use for sweaty odor (malodor) by smelling to T-shirts. If a sweaty odor was detected, a mark (X) was added in the table below. The observations below show that washing with DNase during 10 washes prevents accumulation of odor in a subsequent laundering process where no DNase is used.

Example 4

A wash experiment was conducted on a collection of running clothes (sweatshirts and running T-shirts), which had been worn during training exercises for at least 50 times. During the training exercises the running clothes had become damp of sweat but generally not soiled. The running clothes had previous been washed in a Miele Softtronic W5825 at 30° C. (low filling of the machine) using BioTex Black (Unilever) in a recommended standard dose.

Before conducting the present experiment, the sweatshirt and running T-shirt (100% polyester) was evaluated by a trained odor panelist, who found a pronounced odor of sour sweat (malodor), in particular, present in the armpit of the clothes. The malodor was present after washing the clothes using BioTex Black and the malodor accumulated with the number of times the running clothes were used.

The running clothes was washed in a Miele Softtronic W5825 at 30° C. (low filling of the machine) using standard dose of BioTex black and a dose of A. oryzae DNase (0.4 ppm).

Between each training exercises, the running clothes were subjected to another round of assessment by the odor panelist. The odor panelist found that the malodor was significantly reduced and hardly detectable after 1 to 3 washing cycles in the presence of the A. oryzae DNAse of the present invention. In an extending study, the running clothes were washed in the presence of the A. oryzae DNAse of the present invention every time the clothes were washed. The odor panelist found that when the running clothes had been washed in the presence of the A. oryzae DNAse it could be worn for at least two training exercises (allowing the clothes to dry without washing the clothes between the training exercises) before malodor was clearly detectable.

Example 5
Odor Removal by DNase (E-Nose)

Preparation of DNA Swatches with E-2-Nonenal

Chromosomal DNA from Pseudomonas sp. was isolated by QIAamp DNA Blood Mini Kit following the manufactures instructions (Qiagen, Hilden, Germany). Polyester swatches (WFK30A) (2 cm in diameter) were sterilized in a Holm & Halby Systec DB-23 autoclave for 60 minutes at 121° C. 100 μl of purified Pseudomonas sp. DNA diluted to a final concentration of 1 ng/μl was added on each of the autoclaved swatches and swatches were dried under continuous flow in a Laminar Air Flow Bench for 2 hours. After drying, 10 swatches with DNA were placed in a sterile 25 mL NUNC tube (364238; Thermo Scientific), and 10 ml of 0.2 mM E-2-Nonenal (255653; Sigma-Aldrich) was added (Assay II). The tube was placed in a Stuart rotator (miniLOM) (20 rpm at room temperature for 20 min). The 10 swatches were transferred to a 50.000 MWCO centrifugal tube (VS203, Vivaspin 20, Satorius). The tubes were centrifuged at 3000 g at 21° C. in 1 min, and the 10 swatches were split into 2 sterile NUNC tubes (364238; Thermo Scientific) with 5 swatches in each tube. Additionally, 5 sterile polyester swatches (WFK30A) (2 cm in diameter) without DNA and E-2-nonenal were added to each of the tubes. The swatches without DNA were marked allowing discrimination from swatches with DNA/E-2-nonenal.

Washing Procedure of DNA Swatches with E-2-Nonenal

Wash liquor of Ariel Actilift powder Style&Color and Ariel Actilift powder White were prepared by dissolving 5.0 g of detergent in 1000 ml of sterile MilliQ water with a hardness of 15° dH (EU conditions). Wash liquor of Tide Pods was prepared by dissolving 1.8 g of the white phase detergent in 1000 ml of sterile milliQ water with a hardness of 6° dH. Wash liquors were left on a magnetic stirrer for 20 min prior to use.

Wash liquor (10 ml) was added to each of the two identical tubes with 5 DNA swatches with E-2-nonenal and 5 sterile swatches, 10 μl of Apergillus oryzae DNAse of the present invention resulting in a final concentration of 5 ppm was added to one of the tubes. The tubes were placed in a Stuart rotor (20 rpm at 30° C. for 60 min). Wash liquor was poured off, and swatches were rinsed twice with 20 mL of sterile milliQ water with hardness 15° dH. Swatches from each tube were transferred to a 50.000 MWCO centrifugal tube (VS203, Vivaspin 20, Satorius) and centrifuged at 3000 g at 21° C. in 1 min. Each swatch with E-2-nonenal was then transferred to a 20 mL GC headspace vial, using clean, sterile tweezers to place each swatch one swatch in each vial. They were then analyzed in an Alpha MOS HERACLES Flash Gas Chromatography Electronic Nose, equipped with a Restek MXT-5 capillary column, with an HS100 autosampler and an FID detector.

Conclusion: DNA-trapped odor on textile can be removed with the Apergillus oryzae DNAse, thus resulting in odor reduction.

Example 6
Odor Removal by DNase (Sensory Analysis)

Polyester and cotton swatches (2 cm in diameter) were soiled with Pseudomonas sp. DNA and 0.5 mM E-2-nonenal (255653; Sigma Aldrich) (see Example 5 for details on prepration of the DNA swatches) and washed in Stuart rotator (miniLOM) 60 min at 30° C. in model detergent A (prepared by dissolving 3.33 g in 1 liter of milliQ water with hardness 15° dH) in the presence or absence of Apergillus oryzae DNAse of the present invention (5 ppm). After washing, swatches were rinsed twice in 20 ml of MilliQ water with hardness 15° dH. The swatches were evaluated for the perceived intensity of E-2-nonenal by four odor panelist (samples where blinded). For evaluation a perceived intensity scale going from 0 to 9 was used. 0 indicated no perceived intensity of E-2-Nonenal, whereas 9 indicated the highest perceived intensity of E-2-Nonenal. Results showed consensus within all four odor panelists.

Assay for Visual Determination of Odor Removal

Brevundimonas sp. was pre-grown on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131; Oxoid Ltd, Basingstoke, UK) for 2-5 days at 30° C. From a single colony, a loop-full was transferred to 10 mL of TSB and incubated for 20 hours at 30° C. with shaking (240 rpm). After propagation, Brevundimonas sp. was pelleted by centrifugation (Sigma Laboratory Centrifuge 6K15) (3000 g at 21° C. in 7 min) and resuspended in 10 mL of TSB diluted twice with water. Optical density (OD) at 600 nm was measured using a spectophometer (POLARstar Omega (BMG Labtech, Ortenberg, Germany). Fresh TSB diluted twice with water was inoculated to an OD600 nm of 0.03, and 20 mL was added to a petri dish, in which 5 cm×5 cm swatch of sterile Polyester WFK30A was placed. After incubation (24 hours at 15° C. with shaking (75 rpm), swatches were rinsed twice with 0.9% (w/v) NaCl. Swatches were washed in TOM either directly after rinsing or after drying for 24 hours in a LAF bench.

The visual indicating agent Phenol red in solution was prepared by dissolving 0.1 g in 100 ml 99% Ethanol. Indicator solution (50 μL) was added to a filter paper (diameter 2 cm) and dried overnight in fume hood to form an odour capturing agent including the visual indicating agent (Phenol red). Four washed swatches were placed in the bottom of a glass container (one container for each swatch) and 500 μL of 17% TSB was added. As a control, washed clean textile polyester was placed in the bottom of another glass container and 500 μL of 17% TSB was added. The containers with the swatches were incubated at incubated at 37° C. The containers were monitored up to 48 hours to detect change of colour of the Phenol red tracer.
