The present disclosure relates to compositions such as cleaning compositions comprising an enzyme having hexosaminidase activity, as defined herein. The disclosure further relates to the use of said compositions comprising such enzymes in cleaning processes and/or for deep cleaning of organic stains as well as to methods of using said compositions for removal or reduction of components of organic matter.
Cleaning compositions comprising one or more perfumes are well known. The perfumes often have a double function of providing a desired scent and masking undesirable odors. Perfumes may be chemical compounds or, e.g., natural oils such as essential oils and other natural compounds.
Enzymes have been used in cleaning compositions for decades. Usually a cocktail of various enzymes is added to cleaning compositions, wherein each enzyme targets a specific substrate, e.g., amylases are active towards starch stains, proteases on protein stains and so forth. The effectiveness of these commercial enzymes provides cleaning compositions which remove much of the soiling. However, components of organic matters such as biofilm and EPS (extracellular polymeric substance) constitute a challenging type of staining due to the complex nature of such organic matter, and commercially available cleaning compositions are not able to effectively remove or reduce EPS and/or biofilm related stains. Textile surfaces and hard surfaces, such as dishes or the inner space of a laundry or dishwashing machine enduring a number of wash/cleaning cycles, become soiled with many different types of soiling which may be composed of proteins, grease, starch etc. Some types of stain may be associated with organic matter such as biofilm, EPS (extracellular polymeric substance), etc. Organic matter may be composed of different molecules such as polysaccharides, extracellular DNA (eDNA), and proteins. Some organic matter comprises an extracellular polymeric matrix, which may be sticky or glueing, which when present on textile attracts soils and may cause redeposition or backstaining of soil, resulting in a greying of the textile. Additionally, organic matters such as biofilms often cause malodor issues as various malodor molecules can be adhered by the polysaccharides, extracellular DNA (eDNA) and proteins in the complex extracellular matrix and be slowly released to cause a noticeable malodor.
Cleaning compositions and detergents comprising enzymes having hexosaminidase activity are described in WO 2017/186936, WO 2017/186937 and WO 2017/186943. WO 2011/163325 describes various perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or such perfume delivery systems.
Therefore, one objective is to provide a cleaning composition which is able to provide a pleasant scent and reduce malodor, while avoiding the aforementioned problems.
A first aspect relates to a cleaning composition for hard surfaces and textiles, characterized in that the cleaning agent contains from 0.1 to 50 ppm of an enzyme having hexosaminidase activity and one or more perfume component.

The inventors have surprisingly found that enzymes of the GH20 class having hexosaminidase activity act synergistically with volatile perfume compounds.
Such volatile perfume compounds are often added to cleaning compositions to mask malodors. The malodor may come from various sources. One example is build up of organic matter such as sebum, body soils, cell debris, biofilm, EPS etc. It has previously been shown that enzymes having hexosaminidase activity can reduce stains related to organic material such as biofilm and EPS, e.g., PNAG (poly-N-acetylglucosamine); see WO 2017/186936, WO 2017/186937 and WO 2017/186943. The enzymes are preferably dispersins having 1,6 beta-N-acetylglucosamine activity. The effect of these enzymes as described in the above prior art is among other things, reduction of malodor, e.g., associated with laundry textiles. Built-up organic stains are often difficult to remove, and commercial detergents do not effectively reduce the malodor. Instead the malodor is masked by the use of various perfume substances, which consumers often will experience as a cleaning effect despite the sources of the malodors not actually being removed. As a result, even more perfume needs to be added over time to prevent textiles from smelling increasingly worse. Many perfume substances have side-effects such as being allergenic, which may appear as skin rash. Also many of these substances being chemicals of nature are bad for the environment when disposed of in waste water. In recent years, perfumes are increasingly employed in the form of perfume microcapsules, microcapsules being considered as microplastics and, hence, potentially bad for the environment. Further, perfumes are expensive and add to the total cost of the cleaning compositions. Thus, perfume substances may cause various negative consequences for the consumer. The present disclosure addresses these problems, by providing a new class of enzymes for cleaning, which in addition to removing and reducing malodor by themselves further provide synergistic effects with the perfume substances and thereby significantly reduce the need for adding perfume to cleaning compositions, in particular such as laundry compositions.
Thus, one embodiment relates to a cleaning composition comprising an enzyme having hexosaminidase activity, where the amount of perfume is reduced compared to traditional cleaning compositions.
The compositions comprising an enzyme having hexosaminidase activity, in particular a dispersin, and one or more perfume component, effectively reduce or limit malodor of, e.g., textiles or hard surfaces such as dishes, while providing reduction/removal of organic components such as PNAG from surfaces such as textiles and hard surfaces, e.g., dishes, and while providing reduction/limitation of redeposition (when applied in, e.g., laundry processes) and while improving whiteness of textiles.
A composition is preferably a cleaning composition comprising at least one enzyme having hexosaminidase activity, in particular a dispersin, and one or more perfume component, as defined herein. In the field of cleaning compositions, perfumes and perfume oils are used to provide the treated surfaces with a pleasant odor. The term “perfumes” include perfume raw materials and compositions, scents, flavours, and oils, e.g., essential oils. A wide variety of chemicals are known for fragrance (i.e., perfume) uses, including compounds such as aldehydes, ketones and esters. More commonly, naturally occurring plant and animal oils and exudates comprising complex mixtures of various chemical components are known for use as fragrances.
One embodiment relates to a cleaning composition comprising one or more perfumes preferably present in the range from 0.0005 to 5 wt.%, more preferably 0.0001 to 3 wt.%, more preferably 0.005 to 2 wt.%, even more preferably 0.001 to 0.5 wt.%, still even more preferably 0.05 to 0.5 wt.%, most preferably 0.1 to 1 wt.%. In a preferred embodiment, such cleaning composition is a laundry cleaning composition.
One embodiment relates to a cleaning composition for hard surfaces and/or textiles, characterized in that said cleaning composition contains from 0.1 to 50 ppm of an enzyme having hexosaminidase activity and from 0.0005 to 5 wt.%, more preferably 0.0001 to 3 wt.%, more preferably 0.005 to 2 wt.%, even more preferably 0.001 to 0.5 wt.%, still even more preferably 0.05 to 0.5 wt.%, most preferably 0.1 to 1 wt.% of one or more perfume component. The enzyme is preferably a dispersin and preferably has 1,6 beta-N-acetylglucosamine activity. Thus one embodiment relates to a cleaning composition for hard surfaces and/or textiles, characterized in that said cleaning composition contains from 0.1 to 50 ppm dispersin, preferably having 1,6 beta-N-acetylglucosamine activity and from 0.0005 to 5 wt.%, more preferably 0.0001 to 3 wt.%, more preferably 0.005 to 2 wt.%, even more preferably 0.001 to 0.5 wt.%, still even more preferably 0.05 to 0.5 wt.%, most preferably 0.1 to 1 wt.% of one or more perfume component.
The term hexosaminidase includes “dispersin” and the abbreviation “Dsp”, and means a polypeptide having hexosaminidase activity, EC 3.2.1., that catalyzes the hydrolysis of β-1,6-glycosidic linkages of N-acetyl-glucosamine polymers found in, e.g., biofilm. The term hexosaminidase includes polypeptides having N-acetylglucosaminidase activity and β-N-acetylglucosaminidase activity. The term “polypeptide having hexosaminidase activity” may be used interchangeably with the term “hexosaminidases” and similarly the term “polypeptide having β-N-acetylglucosaminidase activity” may be used interchangeably with the term “β-N-acetylglucosaminidases”. For purposes herein, hexosaminidase activity is determined according to the procedure described in Assay l. In a preferred embodiment, the polypeptide having hexosaminidase activity is a dispersin. In a preferred embodiment, the polypeptide having hexosaminidase activity is a β-N-acetylglucosaminidase targeting poly-β-1,6-N-acetylglucosamine.

Suitable perfumes and perfume components may be provided by the CTFA (Cosmetic, Toiletry and Fragrance Association) 1992 International Buyers Guide, published by CFTA Publications and OPD 1993 Chemicals Buyers Directory 80th Annual Edition, published by Schnell Publishing Co.
The preferred perfumes that may be used are not subject to any restrictions. Thus, in particular synthetic or natural odorant substance compounds of the types esters, ethers, aldehydes (fragrance aldehydes, odorant aldehydes), ketones (fragrance ketones, odorant ketones), alcohols, hydrocarbons, acids, carbonic acid esters, aromatic hydrocarbons, aliphatic hydrocarbons, saturated and/or unsaturated hydrocarbons and mixtures of these may be used as perfume substances.
Individual perfume compounds, e.g., synthetic products of the ester, ether, aldehyde, ketone, alcohol, and hydrocarbon types, can be used as well as mixtures thereof. It is preferred, however, to use mixtures of different perfumes, which together generate an attractive scent note. Such mixtures can also contain natural perfume mixtures such as those accessible from plant sources, e.g., pine, citrus, jasmine, patchouli, rose, or ylang-ylang oil. In order to be perceptible, a perfume must be volatile; in addition to the nature of the functional groups and the structure of the chemical compound, the molecular weight also plays an important part. Most perfumes possess molar weights of up to approximately 200 g/mol, while molar weights of 300 g/mol and above are rather exceptional. Because of the differing volatility of perfumes, the odor of a perfume made up of multiple perfumes changes during volatilization, the odor impressions being subdivided into a “top note”, “middle note” or “body,” and “end note” or “dry out.” Because the perception of an odor also depends in a large part on the odor intensity, the top note of a perfume or scent is not made up only of highly volatile compounds, while the end note comprises for the most part less-volatile, i.e., adherent perfumes.
Suitable perfumes of the ester type include, e.g., benzyl acetate, phenoxy ethyl isobutyrate, p-tert-butyl cyclohexyl acetate, linalyl acetate, dimethyl benzyl carbinyl acetate (DMBCA), phenyl ethyl acetate, ethyl methyl phenyl glycinate, allyl cyclohexyl propionate, styrallyl propionate, benzyl salicylate, cyclohexyl salicylate, floramate, melusate and jasmacyclate.

Useful components of the perfume include materials of both natural and synthetic origin. They include single compounds and mixtures. Specific examples of such components may be found in, e.g., Fenaroli’s Handbook of Flavor Ingredients, 1975, CRC Press; Synthetic Food Adjuncts, 1947 by M. B. Jacobs, edited by Van Nostrand; or Perfume and Flavor Chemicals by S. Arctander 1969, Montclair, N.J. (USA). It is commonplace for a plurality of perfume components to be present in a cleaning composition. In the compositions it is envisaged that there will be four or more, preferably five or more, more preferably six or more or even seven or more different perfume components.
The perfume mixtures preferably comprise top notes, which are defined by Poucher (Journal of the Society of Cosmetic Chemists 6(2):80, 1955). Preferred top notes are selected from citrus oils, linalool, linalyl acetate, lavender, dihydro myrcenol, rose oxide and cis-3-hexanol. The International Fragrance Association publices lists of fragrance ingredients http://www.ifraorg.org/enus/ingredients#.XMqixOgza71. The list of 3999 materials reported as used in fragrance compounds in 2015 is hereby incorporated by reference, https://ifrafragrance.org/initiatives/transparency/ifratransparency-list.
It is conventional knowledge in the art that the degree of hydrophobicity of a perfume ingredient may be correlated with its octanol/water partitioning coefficient P. The octanol/water partitioning coefficient of a fragrance ingredient is the ratio between its equilibrium concentration in octanol and in water. A fragrance ingredient with a greater partitioning coefficient P is more hydrophobic. Conversely, a fragrance ingredient with a smaller partitioning coefficient P is more hydrophilic. Since the partitioning coefficients of the perfume ingredients normally have high values, they are more conveniently given in the form of their logarithm to the base 10, logP. The logP value is a constant defined as
LogP = log10 (Partition Coefficient) Partition Coefficient, P = [organic]/[aqueous].
In particular embodiments, the logP values are more conveniently calculated by the “CLOGP” program, available from Daylight Chemical Information Systems. The “calculated logP” (ClogP) is determined by the fragment approach of Hansch & Leo (cf., Leo, in Comprehensive Medicinal Chemistry, Vol. 4, Hansch, et al., Eds., p. 295, Pergamon Press, 1990). In one embodiment the ClogP of the perfume component to be incorporated in the cleaning composition is in the range of -1.0 to 4.0. In other embodiments, the ClogP of the perfume component is in the range of 0.0 to 4.0, 1.0 to 4.0, 2.0 to 4.0, or 3.0 to 4.0. In yet other embodiments, the ClogP of the fragrance formulation is in the range of 0.0 to 3.0, 1.0 to 3.0, or 2.0 to 3.0.
Non-limiting examples of perfumes that have ClogP values in the range of -1.0 to 4.0 are allyl heptanoate, anethole USP, benzaldehyde, benzyl acetate, cis-3-hexenyl acetate, cis-jasmone, coumarin, dihydro myrcenol, dimethyl benzyl carbinyl acetate, ethyl vanillin, eucalyptol, eugenol, isoeugenol, isobutyl salicylate, floracetate, geraniol, hydroxy citronellal, koavone, LIFFAROME, dihydro linalool, linalool, methyl anthranilate, methyl-beta-naphthyl ketone, methyl dihydro jasmonate, nerol, nonalactone, orange flower ether, phenyl ethyl acetate, phenyl ethyl alcohol, phenyl propyl alcohol, phenoxy ethyl isobutyrate, phenoxanol, alpha-terpineol, tetrahydro linalool, beta-terpineol, vanillin, and mixtures thereof.
It is advantageous to encapsulate perfume components which have a low ClogP (i.e., those which will have a greater tendency to be partitioned into water), preferably with a ClogP of less than 3.0. These materials, of relatively low boiling point and relatively low ClogP have been called the “delayed blooming” perfume ingredients and include one or more of the following materials: allyl caproate, amyl acetate, amyl propionate, anisic aldehyde, anisole, benzaldehyde, benzyl acetate, benzyl acetone, benzyl alcohol, benzyl formate, benzyl isovalerate, benzyl propionate, beta-gamma hexenol, camphor gum, laevo-carvone, d-carvone, cinnamic alcohol, cinamyl formate, cis-jasmone, cis-3-hexenyl acetate, cuminic alcohol, cyclal c, dimethyl benzyl carbinol, dimethyl benzyl carbinol acetate, ethyl acetate, ethyl aceto acetate, ethyl amyl ketone, ethyl benzoate, ethyl butyrate, ethyl hexyl ketone, ethyl phenyl acetate, eucalyptol, eugenol, fenchyl acetate, floracetate (tricyclo decenyl acetate), frutene (tricyclco decenyl propionate), geraniol, hexenol, hexenyl acetate, hexyl acetate, hexyl formate, hydratropic alcohol, hydroxycitronellal, indone, isoamyl alcohol, isomenthone, isopulegyl acetate, isoquinolone, ligustral, linalool, linalool oxide, linalyl formate, menthone, menthyl acetphenone, methyl amyl ketone, methyl anthranilate, methyl benzoate, methyl benzyl acetate, methyl eugenol, methyl heptenone, methyl heptine carbonate, methyl heptyl ketone, methyl hexyl ketone, methyl phenyl carbinyl acetate, methyl salicylate, methyl-n-methyl anthranilate, nerol, octalactone, octyl alcohol, p-cresol, p-cresol methyl ether, p-methoxy acetophenone, p-methyl acetophenone, phenoxy ethanol, phenyl acetaldehyde, phenyl ethyl acetate, phenyl ethyl alcohol, phenyl ethyl dimethyl carbinol, prenyl acetate, propyl bornate, pulegone, rose oxide, safrole, 4-terpinenol, alpha-terpinenol, and/or viridine. Another group of perfumes are the aromatherapy materials, which include many components also used in perfumery, including components of essential oils such as Glary Sage, Eucalyptus, Geranium, Lavender, Mace Extract, Neroli, Nutmeg, Spearmint, Sweet Violet Leaf and Valerian.

The cleaning composition may comprise one or more surfactants, which may be anionic and/or cationic and/or non-ionic and/or semi-polar and/or zwitterionic, or a mixture thereof. In a particular embodiment, the cleaning composition includes a surfactant system (comprising more than one surfactant), e.g., a mixture of one or more nonionic surfactants and one or more anionic surfactants.
In one embodiment the detergent comprises at least one anionic surfactant and at least one non-ionic surfactant, the weight ratio of anionic to nonionic surfactant may be from 10:1 to 1:10. In one embodiment the amount of anionic surfactant is higher than the amount of non-ionic surfactant, e.g., the weight ratio of anionic to non-ionic surfactant may be from 10:1 to 1.1:1 or from 5:1 to 1.5:1. The amount of anionic to non-ionic surfactant may also be equal and the weight ratios 1:1. In one embodiment the amount of non-ionic surfactant is higher than the amount of anionic surfactant and the weight ratio may be 1:10 to 1 :1.1. Preferably the weight ratio of anionic to non-ionic surfactant is from 10:1 to 1:10, such as from 5:1 to 1:5, or from 5:1 to 1 :1.2.

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 cleaning compositions allows, e.g., more concentrated formulations of surfactants (as in the process of compacting liquid cleaning compositions by removing water) without inducing undesired phenomena such as phase separation or high viscosity.
The cleaning composition may contain 0 to 10 wt.%, e.g., 0 to 5 wt.%, such as about 0.5 to about 5 wt.%, or about 3 to about 5 wt.%, of a hydrotrope. Any hydrotrope known in the art for use in cleaning may be utilized. Non-limiting examples of hydrotropes include sodium benzene sulfonate, sodium p-toluene sulfonate (STS), sodium xylene sulfonate (SXS), sodium cumene sulfonate (SCS), sodium cymene sulfonate, amine oxides, alcohols and polyglycol ethers, sodium hydroxy naphthoate, sodium hydroxy naphthalene sulfonate, sodium ethyl hexyl sulfate, and combinations thereof.
The cleaning composition may contain 0 to 50 wt.%, such as about 1 to about 40 wt.%, such as about 1 to about 30 wt.%, such as about 1 to about 20 wt.%, such as about 0.01 to about 10 wt.% of a bleaching system. Any bleaching system comprising components known in the art for use in cleaning detergents may be utilized. Suitable bleaching system components include sources of hydrogen peroxide; peracids and/or sources of peracids (bleach activators); and bleach catalysts or boosters.
Suitable sources of hydrogen peroxide are inorganic persalts, including alkali metal salts such as sodium percarbonate and sodium perborates (usually mono- or tetrahydrate), and hydrogen peroxide urea (1/1).
Peracids may be (a) incorporated directly as preformed peracids or (b) formed in situ in the wash liquor from hydrogen peroxide and a bleach activator (perhydrolysis) or (c) formed in situ in the wash liquor from hydrogen peroxide and a perhydrolase and a suitable substrate for the latter, e.g., an ester.
a) Suitable preformed peracids include, but are not limited to, peroxy carboxylic acids such as peroxy benzoic acid and its ring-substituted derivatives, peroxy-α-naphthoic acid, peroxy phthalic acid, peroxy lauric acid, peroxy stearic acid, ε-phthalimido peroxy caproic acid [phthalimido peroxy hexanoic acid (PAP)], and o-carboxy benzamido peroxy caproic acid, aliphatic and aromatic diperoxy dicarboxylic acids such as diperoxy dodecane dioic acid, diperoxy azelaic acid, diperoxy sebacic acid, diperoxy brassylic acid, 2-decyl diperoxy butane dioic acid, and diperoxy phthalic, -isophthalic and -terephthalic acids, perimidic acids, peroxy monosulfuric acid, peroxy disulfuric acid, peroxy phosphoric acid, peroxy silicic acid, and mixtures thereof. It is understood that the peracids mentioned may in some cases be best added as suitable salts, such as alkali metal salts (e.g., Oxone®) or alkaline earth-metal salts.
b) Suitable bleach activators include those belonging to the class of esters, amides, imides, nitriles or anhydrides and, where applicable, salts thereof. Suitable examples are tetraacetyl ethylene diamine (TAED), sodium 4-[(3,5,5-trimethyl hexanoyl)-oxy] benzene-1-sulfonate (ISONOBS), sodium 4-(dodecanoyloxy) benzene-1-sulfonate (LOBS), sodium 4-(decanoyloxy) benzene-1-sulfonate, 4-(decanoyloxy) benzoic acid (DOBA), sodium 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 0624154 and particularly preferred in that family is acetyl triethyl citrate (ATC). ATC or a short chain triglyceride like triacetin has the advantage that they are environmentally friendly. Furthermore, acetyl triethyl citrate and triacetin have good hydrolytical stability in the product upon storage and are efficient bleach activators.

One embodiment relates to a method of deep cleaning on an item, comprising the steps of:
“Biofilm” is produced by 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, Staphylococcus aureus and Stenotrophomonas sp. In one aspect, the biofilm producing strain is Brevundimonas sp. In one aspect, the biofilm producing strain is Pseudomonas particularly, Pseudomonas aeruginosaPseudomonas alcaliphila or Pseudomonas fluorescens. In one aspect, the biofilm producing strain is Staphylococcus aureus.
By the term “deep cleaning” is meant disruption or removal of components of organic matter, e.g., sebum, cell debris, body soils, biofilm, such as polysaccharides, e.g., PNAG (poly-N-acetyl glucosamine), bodysoil or other components present in the organic matter.
The term “cleaning component”, e.g., a detergent adjunct ingredient, is different from the enzymes, i.e., the dispersin. The precise nature of these additional cleaning components, e.g., adjunct components, and levels of incorporation thereof, will depend on the physical form of the composition and the nature of the operation for which it is to be used. Suitable cleaning components, e.g., adjunct materials include, but are not limited to the components described above such as surfactants, builders, flocculating aid, chelating agents, dye transfer inhibitors, enzymes, enzyme stabilizers, enzyme inhibitors, catalytic materials, bleach activators, hydrogen peroxide, sources of hydrogen peroxide, preformed peracids, polymeric 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 term “cleaning composition” refers to compositions that find use in the removal of undesired compounds from items to be cleaned, such as textiles, e.g., body soil, sebum, biofilm, extracellular polymeric substance (EPS) and cell debris, e.g., dead skin cells. The cleaning composition may be used to,e.g., clean textiles for both household cleaning and industrial cleaning. The term encompasses any materials/compounds selected for the particular type of cleaning composition desired and the form of the product (e.g., liquid, gel, powder, granulate, paste, or spray compositions) and includes, but is not limited to, detergent compositions (e.g., liquid and/or solid laundry detergents and fine fabric detergents, fabric fresheners, fabric softeners and textile and laundry prespotters and pretreatment). In addition to containing the enzyme, the cleaning composition may contain one or more additional enzymes (such as proteases, amylases, lipases, cutinases, cellulases, endoglucanases, xyloglucanases, pectinases, pectin lyases, xanthanases, peroxidases, haloperoxygenases, catalases and mannanases, or any mixture thereof), and/or cleaning components, e.g., detergent adjunct ingredients such as surfactants, builders, chelators or chelating agents, bleach system or bleach components, polymers, fabric conditioners, foam boosters, suds suppressors, dyes, perfume, tannish inhibitors, optical brighteners, bactericides, fungicides, soil suspending agents, anti-corrosion agents, enzyme inhibitors or stabilizers, enzyme activators, transferase(s), hydrolytic enzymes, oxido reductases, bluing agents and fluorescent dyes, antioxidants, and solubilizers.
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. 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.
The term “hard surface cleaning” is defined herein as cleaning of hard surfaces wherein hard surfaces may include floors, tables, walls, roofs etc. as well as surfaces of hard objects such as cars (car wash) and dishes (dishwashing). Dishwashing includes but is not limited to cleaning of plates, cups, glasses, bowls, cutlery such as spoons, knives, forks, serving utensils, ceramics, plastics, metals, china, glass and acrylics.
The term “wash performance” is used as an enzyme’s ability to remove stains present on the object to be cleaned during, e.g., wash or hard surface cleaning.
The term “whiteness” is defined herein as a greying, yellowing of a textile. Loss of whiteness may be due to removal of optical brighteners/hueing agents. Greying and yellowing can be due to soil redeposition, body soils, colouring from, e.g., iron and copper ions or dye transfer. Whiteness may include one or several of the following: colourant or dye effects, incomplete stain removal (e.g., body soils, sebum etc.), redeposition (greying, yellowing or other discolourations of the object, due to removed soils reassociating with other parts of textile, soiled or unsoiled), chemical changes in textile during application, and clarification or brightening of colours.
The term “laundering” relates to both household laundering and industrial laundering and means the process of treating textiles with a solution containing a cleaning or detergent composition. The laundering process can, e.g., be carried out using, e.g., a household or an industrial washing machine or can be carried out by hand.
By the term “malodor” is meant an odor which is not desired on clean items. The cleaned item should smell fresh and clean without malodors adhered to the item. One example of malodor is compounds with an unpleasant smell, which may be produced by microorganisms, cell debris, sebum, and other body soils. Another example is unpleasant smells can be sweat or body odor adhered to an item which has been in contact with human or animal. Another example of malodor can be the odor from spices, which sticks to items such as curry or other exotic spices which smell strongly.
The term “textile” means any textile material including yarns, yarn intermediates, fibers, nonwoven materials, natural materials, synthetic materials, and any other textile material, fabrics made of these materials and products made from fabrics (e.g., garments and other articles). The textile or fabric may be in the form of knits, wovens, denims, non-wovens, felts, yarns, and towelling. The textile may be cellulose based such as natural cellulosics, including cotton, flax/linen, jute, ramie, sisal or coir or manmade cellulosics (e.g., originating from wood pulp) including viscose/rayon, cellulose acetate fibers (tricell), lyocell or blends thereof. The textile or fabric may also be non-cellulose based such as natural polyamides including wool, camel, cashmere, mohair, rabbit and silk or synthetic polymers such as nylon, aramid, polyester, acrylic, polypropylene and spandex/elastane, or blends thereof as well as blends of cellulose based and non-cellulose based fibers. Examples of blends are blends of cotton and/or rayon/viscose with one or more companion material such as wool, synthetic fiber (e.g., polyamide fiber, acrylic fiber, polyester fiber, polyvinyl chloride fiber, polyurethane fiber, polyurea fiber, aramid fiber), and/or cellulose-containing fiber (e.g., rayon/viscose, ramie, flax/linen, jute, cellulose acetate fiber, lyocell). Fabric may be conventional washable laundry, e.g., stained household laundry. When the term fabric or garment is used it is intended to include the broader term textiles as well.
The term “mature polypeptide” means a polypeptide in its final form following translation and any post-translational modifications, such as N-terminal processing, C-terminal truncation, glycosylation, phosphorylation, etc.
The term “variant” means a polypeptide having the activity of the parent or precursor polypeptide and comprising an alteration, i.e., a substitution, insertion, and/or deletion, at one or more positions compared to the precursor or parent polypeptide. A substitution means replacement of the amino acid occupying a position with a different amino acid, a deletion means removal of the amino acid occupying a position, and an insertion means adding an amino acid adjacent to and immediately following the amino acid occupying a position.
The relatedness between two amino acid sequences or between two nucleotide sequences is described by the parameter “sequence identity”. For purposes herein, the sequence identity between two amino acid sequences is determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000, Trends Genet. 16: 276-277), preferably version 6.6.0 or later. The parameters used are a gap open penalty of 10, a gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of Needle labeled “longest identity” (obtained using the -nobrief option) is used as the percent identity and is calculated as follows:
(Identical Residues x 100)/(Length of Alignment - Total Number of Gaps in Alignment)
For purposes herein, the nomenclature [E/Q] means that the amino acid at this position may be a glutamic acid (Glu, E) or a glutamine (Gln, Q). Likewise, the nomenclature [V/G/A/I] means that the amino acid at this position may be a valine (Val, V), glycine (Gly, G), alanine (Ala, A) or isoleucine (Ile, I), and so forth for other combinations as described herein. Unless otherwise limited further, the amino acid X is defined such that it may be any of the 20 natural amino acids. For an amino acid substitution, the following nomenclature is used: Original amino acid, position, substituted amino acid. For example, the substitution of a threonine at position 220 with alanine is designated as “T220A”. Multiple substitutions may be separated by addition marks (“+”), e.g., “T220A + G229V”, representing substitutions at positions 220 and 229 of threonine (T) with alanine (A) and glycine (G) with valine (V), respectively. Multiple substitutions may alternatively be listed with individual mutations separated by a space or a comma. Alternative substitutions in a particular position may be indicated with a slash (“/”). For example, substitution of threonine in position 220 with either alanine, valine or leucine many be designated “T220A/V/L”.

Hexosaminidase activity may be determined using 4-nitrophenyl N-acetyl-β-D-glucosaminide (Sigma-Aldrich) as substrate. The enzymatic reaction is performed in triplicate in a 96 well flat bottom polystyrene microtiter plate (Thermo Scientific) with the following conditions: 50 mM 2-(N-morpholino) ethane sulfonic acid pH 6 buffer, 1.5 mg/ml 4-nitrophenyl N-acetyl-β-D-glucosaminide and 20 µg/ml purified enzyme sample in a total reaction volume of 100 µl. Blank samples without polypeptide are run in parallel. The reactions are carried out at 37° C. in a Thermomixer comfort (Eppendorf). After 10 minutes of incubation, 5 µl 1 M NaOH is added to each reaction mixture to stop the enzymatic reaction. The absorbance is read at 405 nm using a POLARstar Omega plate reader (BMG LABTECH) to estimate the formation of 4-nitrophenolate ion released because of enzymatic hydrolysis of the 4-nitrophenyl N-acetyl-β-D-glucosaminide substrate.
A crude EPS (extracellular polymeric substances) extract was prepared from Pseudomonas fluorescens (isolate from Iceland) as follows: P. fluorescens was restreaked on TSA and incubated for 1 day at 20° C. The strain was inoculated in TSB and incubated overnight at 20° C. After propagation, the culture was diluted (1:100) in M63 supplemented medium (15 mM (NH4)2SO4, 100 mM KH2PO4, 1.8 µM FeSO4, 1 mM MgSO4 • 7H2O, 0.4% (w/v) glycerol, 0.2% (w/v) Casamino acids and 0.0001% (w/v) Thiamine), added to Corning® CellBIND® 225 cm2 angled neck cell culture flasks with vent cap (400 ml per flask) and incubated statically for 3 days at 20° C. The biofilm culture was subsequently pelleted by centrifugation (10 min, 8000 g, 25° C.), and the cells were resuspended in 3 M NaCl (4 ml per flask) and incubated for 30 min at 30° C. to extract the surface-associated EPS. The EPS-containing supernatant obtained after centrifugation (10 min, 5000 g, 25° C.) was stored at -20° C. until further use.
EPS was purified as described in Example 1. After purification, 50 µl aliquots of EPS were added to the wells of 12-well polystyrene flat-bottom microplates (3512, Costar, Corning Incorporated, Corning, NY, USA), in which round swatches (diameter 2 cm) of sterile mix of cotton and polyester (WFK20A 50:50) had been placed. The swatches were incubated for 15 min (static incubation) before proceeding. Eight swatches were placed in 50 ml test tubes and 10 ml of wash liquor (15°dH water with 4.6 g/l liquid Persil Universal Gel detergent, Henkel, Düsseldorf, Germany) and 1.0 ppm enzyme (SEQ ID NO:16) were added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 h at 30° C. at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 20 ml 15°dH water. The swatches from each tube were placed in centrifugation tubes (Maxi-Spin 25 ml Filter Insert 50 ml Tube 0.45 µm Nylon Membrane; Ciro Manufacturing Corporation, Dearfield Beach, USA) and centrifuged at 3000 rpm for 4 min in a Thermo Scientific Sorval Lynx 6000 Centrifuge.
To test for the binding of perfume volatiles bound to the textile, all centrifuged swatches were individually placed in the bottom of 20 mL GC-MS vials (Mikrolab Aarhus A/S, Aarhus, Denmark) and capped with silicone screw top lids (Mikrolab Aarhus A/S, Aarhus, Denmark). Each sample was run in a randomized order, with the headspace from each tube analyzed as follows:
The results show that the addition of dispersin to a wash with commercial detergent reduces and removes biofilm and/or EPS on the textile and thus increases the binding of perfume compounds to the textile.
Heavy soiled tea towels (Warwick Equest Ltd.; County Durham, UK (100% cotton)) were divided into two halves and one group was washed with 1.0 ppm enzyme (SEQ ID NO:16) using tap water and 4.6 g/l liquid Persil Universal Gel detergent (Henkel, Düsseldorf, Germany). The other group functioned as a control and was washed using tap water and 4.6 g/l liquid Persil Universal Gel detergent (Henkel, Düsseldorf, Germany). A Miele laundry washing machine (Miele Softtronic, W2245) with a 30° C. color program was used (run time 1 h, 26 min). After wash, the halved tea towels were hang-dried at room temperature overnight.
To analyze the volatiles of the tea towels, each one was placed in a sealed and inflated polyethylene cooking bag (5 kg - 43 cm × 35 cm × 0.0012 mm, Dagrofa, Ringsted, Denmark). An SPME fiber was pierced through the bag and exposed overnight to the headspace. After extraction the SPME fiber was manually analyzed on a GC-MS with the following specifications:
A Pseudomonas libanensis isolate from worn textile was used in the present example. P. libanensis was restreaked on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131; Oxoid Ltd, Basingstoke, UK) and incubated for 3 days at ambient temperature. A single colony was inoculated into 10 mL of TSB and the culture was incubated for 16 hours at 30° C. with shaking (200 rpm). After propagation, the P. libanensis culture was diluted (1:100) in fresh T-broth (10 g/l Bacto-Tryptone (BD #211699), 5 g/L NaCl (Sigma-Aldrich #31434)) and 2 mL aliquots were added to the wells of 12-well polystyrene flat-bottom microplates (3512; Costar, Corning Incorporated, Corning, NY, USA), in which round sterile textile swatches (diameter 2 cm, cotton/polyester blend (WFK20A)) had been placed. Sterile T-broth was added to control wells. After 72 h at 30° C. (static incubation), the swatches were rinsed twice with 0.9% NaCl.
Pseudomonas libanensis biofilm swatches where prepared as described in Example 4. Four swatches were placed in 50 ml test tubes and 10 ml of wash liquor (16°dH water with 3.09 g/l liquid Persil Universal Gel detergent, Henkel, Düsseldorf, Germany) and 1.0 ppm enzyme (SEQ ID NO:17) were added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 h at 30° C. at 20 rpm. The wash liquor was then removed, and the swatches were rinsed twice with 20 ml 16°dH water. A single piece of plastic biomedia (Hozelock Kaldness K3) was placed at the bottom of 50 ml test tubes, and the swatches from each tube were placed on top and centrifuged at 4000 rpm for 5 min in a Thermo Scientific Sorval Lynx 6000 Centrifuge.
To test for the binding of perfume volatiles bound to the textile, all centrifuged swatches were individually placed at the bottom of 20 mL GC-MS vials (Mikrolab Aarhus A/S, Aarhus, Denmark) and capped with silicone screw top lids (Mikrolab Aarhus A/S, Aarhus, Denmark). Each sample was run in a randomized order, with the headspace from each tube analyzed as follows:
The results show that the addition of dispersin to a wash with commercial detergent increases the binding of perfume compounds to the textile.
