This application contains a Sequence Listing in computer readable form. The computer readable form is incorporated herein by reference.
The present invention relates to cleaning compositions and methods of cleaning comprising endo-β-1,3-glucanase enzyme. The compositions and methods of the invention are suitable for use in household cleaning or treatment compositions, in particular laundry and dish washing compositions, including hand wash and automatic laundry and/or dish washing compositions. The invention is particularly useful for cleaning laundry. The present invention also relates to methods of making cleaning compositions.
In cleaning applications degradation of whiteness is a continuing problem. There are many cleaning technologies aimed at mitigating such problems however, it is a constant challenge to provide improved efficacy and especially in an environmentally favorable manner. These problems are compounded by the increased use of low (e.g., cold water) wash temperatures and shorter washing cycles.
The present inventors have found that natural impurities, particularly present in cotton fibres contribute to whiteness degradation and may also adhere other soils which contact the cotton fibres during use or even during the washing process. Such natural impurities may also be present in soils contacting household items.
Thus, it is an object of the present invention to provide cleaning compositions which can be used in washing, dishwashing and/or cleaning processes, even at low temperatures, which will counteract whiteness degradation and/or remove soils containing natural impurities. It is known to incorporate glucanase enzymes into cleaning compositions, for example as described in WO2005/003319. Such glucanase enzymes hydrolyse glucoside bonds. There are many different glucanase enzymes, for example endo-beta-1,3(4)-glucanase enzymes which hydrolyse both 1,3 and 1,4 linkages in beta glucans as well as endo-beta-1,3:1,4-glucanase enzymes, endo-beta-1,4-glucanase enzymes and endo-beta-1,3-glucanase enzymes. The present inventors have found that certain endo-beta-1,3-glucanase enzymes are particularly useful for stain removal in cleaning compositions comprising surfactant. The invention is particularly useful for laundry detergent compositions.

Parent or Parent endo-β-1,3-glucanase enzyme: The term “parent” or “parent endo-β-1,3-glucanase” means an endo-β-1,3-glucanase to which an alteration is made to produce the enzyme variants. The parent may be a naturally occurring (wild-type) polypeptide or a variant thereof. For example, the parent may be any of SEQ ID Nos: 1, 2, 3, 4, 5, 6 or 7 listed herein.
Sequence Identity: The relatedness between two amino acid sequences or between two nucleotide sequences is described by the parameter “sequence identity”. For purposes of the present invention, the degree of 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 3.0.0 or later. The optional parameters used are gap open penalty of 10, 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×100)/(Length of Alignment−Total Number of Gaps in Alignment)
Alternatively, the parameters used may be gap open penalty of 10, gap extension penalty of 0.5, and the EDNAFULL (EMBOSS version of NCBI NUC4.4) 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 Deoxyribonucleotides×100)/(Length of Alignment−Total Number of Gaps in Alignment)
Variant: The term “variant” means a polypeptide having endo-β-1,3-glucanase activity comprising an alteration/mutation, i.e., a substitution, insertion, and/or deletion, at one or more (e.g. several) positions relative to the parent endo-β-1,3-glucanase. A substitution means a replacement of an amino acid occupying a position with a different amino acid; a deletion means removal of an amino acid occupying a position; and an insertion means adding 1-3 amino acids adjacent to and immediately following an amino acid occupying a position.
Wild-Type Enzyme: The term “wild-type” endo-β-1,3-glucanase means an endo-β-1,3-glucanase expressed by a naturally occurring microorganism, such as a bacterium, yeast, or filamentous fungus found in nature.

Amphiphilic alkoxylated grease cleaning polymers of the present invention refer to any alkoxylated polymer having balanced hydrophilic and hydrophobic properties such that they remove grease particles from fabrics and surfaces. Specific embodiments of the amphiphilic alkoxylated grease cleaning polymers of the present invention comprise a core structure and a plurality of alkoxylate groups attached to that core structure. These may comprise alkoxylated polyalkylenimines, preferably having an inner polyethylene oxide block and an outer polypropylene oxide block.
The core structure may comprise a polyalkylenimine structure comprising, in condensed form, repeating units of formulae (I), (II), (III) and (IV):
wherein # in each case denotes one-half of a bond between a nitrogen atom and the free binding position of a group A1 of two adjacent repeating units of formulae (I), (II), (III) or (IV); * in each case denotes one-half of a bond to one of the alkoxylate groups; and A1 is independently selected from linear or branched C2-C6-alkylene; wherein the polyalkylenimine structure consists of 1 repeating unit of formula (I), x repeating units of formula (II), y repeating units of formula (III) and y+1 repeating units of formula (IV), wherein x and y in each case have a value in the range of from 0 to about 150; where the average weight average molecular weight, Mw, of the polyalkylenimine core structure is a value in the range of from about 60 to about 10,000 g/mol.

Specific embodiments of the amphiphilic alkoxylated grease cleaning polymers may be selected from alkoxylated polyalkylenimines having an inner polyethylene oxide block and an outer polypropylene oxide block, the degree of ethoxylation and the degree of propoxylation not going above or below specific limiting values. Specific embodiments of the alkoxylated polyalkylenimines according to the present invention have a minimum ratio of polyethylene blocks to polypropylene blocks (n/p) of about 0.6 and a maximum of about 1.5(x+2y+1)1/2. Alkoxykated polyalkyenimines having an n/p ratio of from about 0.8 to about 1.2(x+2y+1)1/2 have been found to have especially beneficial properties.
The alkoxylated polyalkylenimines according to the present invention have a backbone which consists of primary, secondary and tertiary amine nitrogen atoms which are attached to one another by alkylene radicals A and are randomly arranged. Primary amino moieties which start or terminate the main chain and the side chains of the polyalkylenimine backbone and whose remaining hydrogen atoms are subsequently replaced by alkylenoxy units are referred to as repeating units of formulae (I) or (IV), respectively. Secondary amino moieties whose remaining hydrogen atom is subsequently replaced by alkylenoxy units are referred to as repeating units of formula (II). Tertiary amino moieties which branch the main chain and the side chains are referred to as repeating units of formula (III).
Since cyclization can occur in the formation of the polyalkylenimine backbone, it is also possible for cyclic amino moieties to be present to a small extent in the backbone. Such polyalkylenimines containing cyclic amino moieties are of course alkoxylated in the same way as those consisting of the noncyclic primary and secondary amino moieties.
The polyalkylenimine backbone consisting of the nitrogen atoms and the groups A1, has an average molecular weight Mw of from about 60 to about 10,000 g/mole, preferably from about 100 to about 8,000 g/mole and more preferably from about 500 to about 6,000 g/mole.
The sum (x+2y+1) corresponds to the total number of alkylenimine units present in one individual polyalkylenimine backbone and thus is directly related to the molecular weight of the polyalkylenimine backbone. The values given in the specification however relate to the number average of all polyalkylenimines present in the mixture. The sum (x+2y+2) corresponds to the total number amino groups present in one individual polyalkylenimine backbone.
The radicals A1 connecting the amino nitrogen atoms may be identical or different, linear or branched C2-C6-alkylene radicals, such as 1,2-ethylene, 1,2-propylene, 1,2-butylene, 1,2-isobutylene, 1,2-pentanediyl, 1,2-hexanediyl or hexamethylene. A preferred branched alkylene is 1,2-propylene. Preferred linear alkylene are ethylene and hexamethylene. A more preferred alkylene is 1,2-ethylene.
The hydrogen atoms of the primary and secondary amino groups of the polyalkylenimine backbone are replaced by alkylenoxy units of the formula (V).
In this formula, the variables preferably have one of the meanings given below: A2 in each case is selected from 1,2-propylene, 1,2-butylene and 1,2-isobutylene; preferably A2 is 1,2-propylene. A3 is 1,2-propylene; R in each case is selected from hydrogen and C1-C4-alkyl, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl and tert.-butyl; preferably R is hydrogen. The index m in each case has a value of 0 to about 2; preferably m is 0 or approximately 1; more preferably m is 0. The index n has an average value in the range of from about 20 to about 50, preferably in the range of from about 22 to about 40, and more preferably in the range of from about 24 to about 30. The index p has an average value in the range of from about 10 to about 50, preferably in the range of from about 11 to about 40, and more preferably in the range of from about 12 to about 30.
Preferably the alkylenoxy unit of formula (V) is a non-random sequence of alkoxylate blocks. By non-random sequence it is meant that the [-A2-O-]m is added first (i.e., closest to the bond to the nitrogen atom of the repeating unit of formula (I), (II), or (III)), the [—CH2—CH2—O-]n is added second, and the [-A3-O-]p is added third. This orientation provides the alkoxylated polyalkylenimine with an inner polyethylene oxide block and an outer polypropylene oxide block.
The substantial part of these alkylenoxy units of formula (V) is formed by the ethylenoxy units —[CH2—CH2—O)]— and the propylenoxy units —[CH2—CH2(CH3)—O]p—. The alkylenoxy units may additionally also have a small proportion of propylenoxy or butylenoxy units -[A2-O]m—, i.e. the polyalkylenimine backbone saturated with hydrogen atoms may be reacted initially with small amounts of up to about 2 mol, especially from about 0.5 to about 1.5 mol, in particular from about 0.8 to about 1.2 mol, of propylene oxide or butylene oxide per mole of NH-moieties present, i.e. incipiently alkoxylated.
This initial modification of the polyalkylenimine backbone allows, if necessary, the viscosity of the reaction mixture in the alkoxylation to be lowered. However, the modification generally does not influence the performance properties of the alkoxylated polyalkylenimine and therefore does not constitute a preferred measure.
The amphiphilic alkoxylated grease cleaning polymers are present in the fabric and home care products, including but not limited to detergents, of the present invention at levels ranging from about 0.05% to 10% by weight of the fabric and home care product.

The invention described and claimed herein is not to be limited in scope by the specific aspects herein disclosed, since these aspects are intended as illustrations of several aspects of the invention. Any equivalent aspects are intended to be within the scope of this invention. Indeed, various modifications of the invention in addition to those shown and described herein will become apparent to those skilled in the art from the foregoing description. Such modifications are also intended to fall within the scope of the appended claims. In the case of conflict, the present disclosure including definitions will control.
The present invention includes a method for cleaning and/or treating a situs inter alia a surface or fabric. In one aspect, such method comprises the steps of optionally washing and/or rinsing said surface or fabric, contacting said surface or fabric with any consumer product disclosed in this specification then optionally washing and/or rinsing said surface or fabric is disclosed.
As used herein, washing includes but is not limited to, scrubbing, and mechanical agitation. Drying of such surfaces or fabrics may be accomplished by any one of the common means employed either in domestic or industrial settings. Such means include but are not limited to forced air or still air drying at ambient or elevated temperatures at pressures between 5 and 0.01 atmospheres in the presence or absence of electromagnetic radiation, including sunlight, infrared, ultraviolet and microwave irradiation. In one aspect, said drying may be accomplished at temperatures above ambient by employing an iron wherein, for example, said fabric may be in direct contact with said iron for relatively short or even extended periods of time and wherein pressure may be exerted beyond that otherwise normally present due to gravitational force. In another aspect, said drying may be accomplished at temperatures above ambient by employing a dryer. Apparatus for drying fabric is well known and it is frequently referred to as a clothes dryer. In addition to clothes such appliances are used to dry many other items including towels, sheets, pillowcases, diapers and so forth and such equipment has been accepted as a standard convenience in many nations of the world substantially replacing the use of clothes lines for drying of fabric. Most dryers in use today use heated air which is passed over and or through the fabric as it is tumbled within the dryer. The air may be heated, for example, either electronically, via gas flame, or even with microwave radiation. Such air may be heated from about 15° C. to about 400° C., from about 25° C. to about 200° C., from about 35° C. to about 100° C., or even from about 40° C. to about 85° C. and used in the dryer to dry a surface and/or a fabric. As will be appreciated by one skilled in the art, the cleaning compositions of the present invention are ideally suited for use in laundry applications. Accordingly, the present invention includes a method for laundering a fabric. The method comprises the steps of contacting a fabric to be laundered with a said cleaning laundry solution comprising at least one embodiment of Applicants' cleaning composition, cleaning additive or mixture thereof. The fabric may comprise most any fabric capable of being laundered in normal consumer or institutional use conditions. The solution preferably has a pH of from about 8 to about 10.5. The compositions may be employed at concentrations of from about 500 ppm to about 15,000 ppm in solution. The water temperatures typically range from about 5° C. to about 90° C. The water to fabric ratio is typically from about 1:1 to about 30:1.
The wash performance of an endo-β-1,3-glucanase on removal of cosmetic stains from cotton was determined in the context of a liquid laundry detergent as follows: Stains were prepared on 5 cm×5 cm swatches of knitted cotton supplied by Warwick Equest Ltd, Consett, U.K. Makeup (Living Nature foundation, Pure Honey 30 ml, product code B0014596QE) was applied by sponge in four places on each swatch using a stencil with 1.2 cm diameter circular holes. The stained swatches were left to line dry for 24 hours before use, and image analysed before testing.
Stain removal testing was conducted using a Tergotometer Detergent Tester, supplied by Copley Scientific Ltd, Nottingham, U.K. Two pots were filled with 400 mL tap water (6.5 grains per US gallon) heated to 40° C., and 1.04 mL Ariel liquid (purchased from Asda Stores Ltd in the UK in February 2019, product code Product Code: 6016650) added to each pot. Two stain swatches, each comprising four stains, were added to each pot, together with 5 cm×5 cm swatches of clean white knitted cotton ballast (Warwick Equest Ltd) to reach a total fabric load of 24 g.
The pots were then agitated, with addition of 0.4 mg active endo-β-1,3-glucanase enzyme (CZ0861, batch 18011, from NZYTech, Lisbon, Portugal) via a pipette to one of the two pots resulting in a wash concentration of 1 ppm active endo-β-1,3-glucanese. This enzyme is described by the supplier as belonging to Glycosyl Hydrolase family 16 and endogenous to Paenibacillus sp., and was confirmed by analysis to have a polypeptide sequence of greater than 98% identity to SEQ ID NO: 1. The temperature was maintained at 40° C. for the duration of the test. After 30 minutes, the wash water was drained, and the fabrics rinsed twice for 5 minutes in 400 mL cold tap water (6.5 grains per US gallon), before placing the washed stain swatches flat on a rack to dry under ambient conditions.
This process was repeated for three more times, with rotation of the treatments between the two pots. This resulted in a total of 32 washed stains per treatment, i.e. 4 external replicates, each comprising 2 swatches of 4 stains.
Pre- and post-analysis of stains was completed using Image Analysis (Illuminant D65/10) to calculate the difference in stain removal between the test and reference formulations.
Stain removal index (SRI) was calculated using the following equation, where AE, is the color difference between the stain-free region of the fabric before washing and the stain before washing, and ΔEAD is the color difference between the stain-free region of the fabric before washing and the stain after washing.
SRI=100*(ΔEAB−ΣEAD)/ΔEAB,
Average test results are presented in the table below. They show that the addition of endo-β-1,3-glucanase leads to a large improvement in stain removal of 22.3 SRI units. This improvement is highly statistically significant, i.e. greater than 99.9% confidence level according to Student's T-test (p<0.001).
The above procedure was repeated but using two stain swatches, each comprising five stains, image analysed for CIELab values (DigiEye, VeriVide, Leicester, U.K.) before testing. The tests were repeated using each of: 0.4 mg active endo-β-1,3-glucanase enzyme (CZ0861, batch 18011, from NZYTech, Lisbon, Portugal); 0.4 mg active endo-β-1,3(4)-glucanase (E-LICACT from Clostridium thermocellum, batch 160201b from Megazyme, Bray Co. Wicklow, Ireland); and 0.4 mg active endo-β-1,4-glucanase (Celluclean 5000L, batch CEN010785 from Novozymes A/S, Bagsvaerd, Denmark).
For each enzyme, the process was carried out four times, with rotation of the treatments between the two pots. This resulted in a total of 40 washed stains per treatment, i.e. 4 external replicates, each comprising 2 swatches of 5 stains. The washed stains were analysed for CIELab as before, and Stain Removal Index (SRI) calculated using the following equation:
The results show that only the endo-β-1,3-glucanase in accordance with the invention significantly improves the removal of makeup stains from cotton, increasing removal from 57 to 74%. This improvement is highly significant and noticeable to the eye.
