Description

DETERGENT COMPOSITIONS FOR LAUNDRY AND / OR FABRIC CARE COMPRISING A TRANSFERASE FIELD OF THE INVENTION The present invention relates to laundry detergents and / or fabric care compositions comprising a transferase.
PREVIOUS TECHNIQUE Laundry detergents and / or fabric care compositions are already known in the art and have great commercial representation. Currently laundry detergent compositions include a complex combination of active ingredients that meet certain specific needs: a surfactant system, enzymes that provide fabric care and cleaning benefits, bleaching agents, a builder system, suds suppressor , dirt suspending agents, soil release agents, optical brighteners, softening agents, dispersing agents, dye transfer inhibiting compounds, abrasives, bactericides, perfumes, and their overall performance have improved over the years. However, the complex nature of the daily "body" spots typically found in pillow cases, T-shirts, collars and socks, provides a challenge to deep cleaning detergents. These stains are difficult to remove completely and often residues accumulate on the fabric causing darkening and a yellow color on the fabric. In addition, the removal by detergents of plant stains, wood, stains based on mud-clay and fruit is one of the greatest cleaning challenges, particularly with the trend of lower wash temperatures and shorter washing cycles. These spots typically contain complex mixtures or fibrous material, based primarily on carbohydrates and their derivatives, fiber components and cell wall. Said spots are generally accompanied by amylose, sugars, and their derivatives. In recent years, there has been an attraction for fabric conditioning compositions by the consumer. Fabric softening compositions impart various attractive properties to treated garments, including softness and static control. The softness of the fabric of a washed garment is typically achieved by supplying a quaternary ammonium compound to the surface of the fabric. Also now the consumer desires permanent ironing cloth garments, particularly cotton cloth garments. Permanent ironing garments include fabrics that resist wrinkling of the fabric both during use and during the washing process. Permanent ironing garments can greatly reduce the manual work associated with the laundry by eliminating the ironing step or reducing the time it takes to perform the necessary ironing on some occasions to prevent wrinkling of the fabric. However, in most commercially available permanent press fabrics, the ability of the fabric to resist wrinkling is reduced over time, as the fabric is repeatedly used and washed. Additionally, colored garments tend to wear out and lose appearance. A portion of this color loss can be attributed to abrasion in the washing process, particularly in automatic clothes washers and dryers. In addition, the loss of tensile strength is presented as an inevitable result of the mechanical / chemical action caused by use / wear or washing. As noted above, there is a continuing need for a laundry detergent composition that provides excellent cleaning of fabrics and / or removal of stains on fabrics, especially in body stains and plant-based stains and / or maintenance of whiteness of the fabrics and / or appearance of color of the fabrics and / or the inhibition of the color transfer. Additionally, there is a continuing need for a detergent composition for laundry and / or fabric care composition, which can provide renovation or restoration properties of tensile strength, against wrinkles, against wear and shrinkage to fabrics, as well how to provide properties or benefits to fabrics of static control, softness to fabrics, appearance of color and against wear.
The aforementioned objectives have been achieved by formulating detergent compositions for laundry and / or for the care of fabrics comprising a transferase. A further objective of the present invention is to provide a laundry detergent composition and / or a fabric care composition comprising a transferase enzyme, which can provide properties to the fabric to renew or restore an improved, improved tensile strength. - Improved wrinkle, anti-damage and anti-shrinkage, as well as providing better properties and benefits of static control, softness of fabrics, appearance of color and against wear, while providing improved cleaning benefits. The aforementioned objectives have been achieved by formulating detergent compositions for laundry and / or fabric care, which additionally comprise a surfactant selected from non-ionic and / or anionic and / or cationic and / or mixtures thereof, a detergent enzyme, a bleaching agent, a color transfer inhibiting polymer, a dispersing agent and / or a smectite clay. Transferase enzymes have been described in the art: EP 560 982 describes a process for producing saccharides of defined chain length such as maltose and maltooligosaccharides in an isolated and high purity form using a saccharide chain transferase such such as cyclodextrin glucosyl transferase or α-amylase. These saccharides produced in the manner described are used in the pharmaceutical field.
US 5,516,689 discloses an enzyme composition and a means to reduce the tackiness of cotton contaminated with honeydew. The transglucosidases and / or pectinases are used to hydrolyze and / or reduce the honeydew in the cotton fiber to reduce the stickiness of said fiber and to avoid serious problems during the milling of the cotton. WO96 / 06931 describes microbial transglutaminases, their production and their use in a variety of industrial purposes, including protein gelling, improvement of flour baking quality, production of pasta-like food material from proteins , fat and water, preparation of cheese starting from dairy concentrates, agglutination of ground meat, improvement of taste and texture of food proteins, casein finish in leather processing, shoe cleaning, etc. JP 7-107971 relates to a microorganism belonging to the genus Bacillus and having the ability to produce a cyclodextrin glucanotransferase. Said enzyme can be used for dishwashing applications, where it demonstrates the decomposition and removal of food soils, and the produced cyclodextrin acts as a concealing and deodorizing agent. In addition, said alkali-resistant glucanotransferase cyclodextrin improves the cleaning capacity of said compositions by improving the foaming properties and the emulsification of the dirt.
Dishwashing detergent compositions containing cyclodextrin glucanotransferase with cleaning benefits and deodorizing effect are described in JP 7-109488. WO97 / 23683 refers to the use of xyloglucan endotransglucosylase (XET), to provide strength and / or retention properties of form and / or wrinkle to cellulosic materials. However, none of the aforementioned documents teaches the benefits of cleaning or care of fabrics obtained by the enzymatic activity of transferase starting from transferases that are not xyloglucan transferases that exhibit a higher transferase activity than hydrolytic activity and / or xyloglucan transferases that exhibit higher reaction rates for donor substrates with higher molecular weight than for donor substrates with lower molecular weight, when used in washing and / or fabric care procedures.
BRIEF DESCRIPTION OF THE INVENTION The present invention relates to detergent compositions for washing and / or care of fabrics comprising a transferase to provide fabric care and cleaning benefits.
DETAILED DESCRIPTION OF THE INVENTION Transferase enzymes and their substrates An essential component of the detergent compositions for laundry and / or fabric care of the present invention is a transferase enzyme. Transferase enzymes catalyze the transfer of functional compounds to a range of substrates. Particularly, the transferases of the invention have the potential to transfer a chemical moiety, for example a methyl group or a glucosyl group, from a small substrate to form oligomeric molecules or elongated polymeric compounds. Using small substrates, the enzyme improves the properties of the garments by linking functional groups such as methyl, hydroxymethyl, formyl, carboxyl, aldehyde, ketone, acyl, amino and phosphorus functional groups, and / or transferring glucosyl residues to the surface of the clothes The improved properties of the garments include properties of resistance to tension, anti-wrinkle, anti-shrinkage and anti-damage to fabrics, properties and benefits of static control, softness of fabrics, appearance of color and anti-wear of fabrics. When the level of transferase is high and the substrate concentration is low, the functional groups are transferred to water molecules providing cleaning benefits. Transferases suitable for the present invention are represented by EC 2.1 enzymes that transfer a carbon group, EC 2.2 enzymes that transfer aldehyde or ketone residues, EC 2.3 acyltransferases, EC 2.4 glycosyltransferases, EC 2.5 enzymes that transfer alkyl or aryl groups that do not they are methyl groups, EC 2.6 enzymes that transfer nitrogen groups and EC 2.7 enzymes that transfer phosphorus-containing groups. Examples of suitable transferases are: EC 2.1.1.15 fatty acid O-methyltransferase EC 2.1.1.18 polysaccharide O-methyltransferase EC 2.1.2.1 glycine hydroxymethyltransferase EC 2.1.2.4 glycine formiminotransferase EC 2.2.1.3 formaldehyde transketolase EC 2.3.1.3 glucosamine N-acetyltransferase EC 2.3.1.18 galactoside acetyltransferase EC 2.3.1.57 diamine N-acetyltransferase EC 2.3.1.75 long-chain alcohol O-acyltransferase EC fat 2.3.1.79 maltose O-acetyltransferase EC 2.3.1.84 alcohol O-acetyltransferase EC fat 2.3.1.88 peptide aN-acetyltransferase EC 2.3.1.96 glycoprotein N-palmitoyltransferase EC 2.3.1.142 glycoprotein O-acyltransferase EC fat 2.5.1.10 geranyltransferase EC 2.5.1.20 cis-polyprimilcistransferase rubber EC 2.6.1 aminotransferase For specific applications, the preferred transferases show little or a large part of its activity in alkaline conditions, that is, enzymes that have an enzymatic activity of at least 10%, preferably at least 25%, most preferably at least 40% of its maximum activity at a pH ranging from 7 to 12. The transferases that are most preferred are enzymes that have their maximum activity at a pH that It varies from 7 to 12, preferably 10.5. Another transferase that is preferred is a transferase having at least 50% of its maximum activity between 10 ° C and 50 ° C. The transferases that are preferred for the detergent compositions for laundry and / or fabric care of the present invention are included in the classes of acyltransferases (EC 2.3) and glucosyltransferases (EC 2.4). Of particular interest is the acyltransferase group, especially the aminoacyltransferases (EC 2.3.2). These are enzymes that transfer amino groups from a donor, usually an amino acid, to a receptor. Even more preferred is the protein-glutamine? -glutamyltransferase (EC 2.3.2.13), also available under the name transglutaminase. Without wishing to be bound by theory, it is believed that enzymatic entanglement of amino acids, di / tri / polypeptides and / or proteins will occur on the web, resulting in increased stress resistance and improved appearance. In addition, hydrolysis by an aminoacyltransferase of said substrates present in the soils / stains will provide cleaning benefits.
Of particular interest is also the group of glycosyltransferases. The general properties of these enzymes are to transfer one sugar of oligosaccharides to another carbohydrate as a receptor. Both hexosyltransferases and pentosyltransferases can be used in the invention. The glycosyltransferases catalyze both hydrolytic and transfer reactions in the incubation with oligosaccharides. As a result of the enzymatic activity, the oligosaccharides are converted to a new class of polysaccharides. It has unexpectedly been found that glycosyltransferases improve the tensile strength and the appearance of fabrics, for example, they reduce wrinkles in the fabric. Without wishing to be bound by any theory, it is believed in fact that thanks to the activity of the glycosyltransferase, the oligosaccharides bind to the cellulose polymers of cotton fabrics resulting in improved tensile strength and demonstrating benefits of appearance, especially after several washing cycles. Without wishing to be bound by theory, it is believed that the activity of the glycosyltransferase has three potential modes of action that provide fabric care benefits: - Enzymatic linkage in which the enzyme is believed to bind oligosaccharides to cellulose fibers with resistance to reduced tension; - Enzymatic entanglement in which the glycosyltransferase is believed to bind cellulose fibers with reduced tensile strength and - Enzymatic polymer entanglement in which the polymers are bonded to cellulose fibers with reduced tensile strength.
In addition, in the presence of a low level of substrate and a high level of glucosyltransferase, the glucosyl groups are transferred to water molecules, thereby providing cleaning benefits. For example, transglucosidase is an enzyme that catalyzes both hydrolytic and transfer reactions in solutions containing a-D-glyco-oligosaccharides. As a result of the enzymatic reactions of transglucosidase, the malto-oligosaccharides are converted to isomalto-oligosaccharides, providing a new class of polysaccharides characterized by a higher proportion of saccharides linked by α-D-1, 6 bonds from the non-reducing end. It has been found that these transglycosidases provide fabric care performance. It is believed that improved tensile strength, reduced wrinkling and better appearance is due to oligosaccharides bound to cotton cellulose polymer fibers. Examples of suitable glycosyltransferases are galactosyltransferases and fructosyltransferases, such as 1,4-β-galactosyltransferase; 1,3-a-fructosyltransferase; 2,3-sialyltransferase; cyclodextrin glucosyltransferase; N-acetylgluco- or -galactosaminyltransferase; and EC 2.4.1.2 1, 4-aD-glucan: 1,6-aD-glucan 6-aD-glucosyltransferase EC 2.4.1.4 Sucrose: 1, 4-aD-gIucano 4-aD-glucosyltransferase EC 2.4.1.5 Sucrose: 1 , 6-aD-glucan 6-aD-glucosyltransferase EC 2.4.1.9 Sucrose: 2,1-β-D-fructan 1-β-D-fructosyltransferase EC 2.4.1.10 Sucrose: 2,6-β-D-fructan 6- β-D-fructosyltransferase EC 2.4.1.11 UDP glucose: glycogen 4-D-glucosyltransferase EC 2.4.1.12 UDP glucose: 1,4-β-D-glucan 4-β-D-glucosyltransferase EC 2.4.1.13 UDP glucose: D -fructose 2-aD-glucosyltransferase EC 2.4.1.16 UDP-N-acetylglucosamine: chitin 4-β-N-acetylglucosaminyl-transferase EC 2.4.1.18 1,4-aD-glucan: 1,4-aD-glucan 6-aD- (1, 4-aD-glucan) -transferase EC 2.4.1.19 1, 4-aD-glucan 4-D- (1, 4-aD-glucan) -transferase (cyclization) EC 2.4.1.21 ADP glucose: 1, 4-aD-glucan 4-aD-glucosyltransferase EC 2.4.1.24 1, 4-D-glucan: 1,4-aD-gIucane (D-glucose) 6-aD-glucosyltransferase EC 2.4.1.25 1, 4-aD-glucan: 1,4-aD-glucan 4-aD-glucosyltransferase EC 2.4.1.29 GDPglucose: 1,4-β-D-glucan 4-β-D-glucosyltransferase EC 2.4.1.34 1 , 3-ß-glucan synthetase EC 2.4.1.35 UDPgIucose: phenol ß-D-glucosyltransferase EC 2.4.1.49 1, 4-ß-D-oligo-D-glucan: orthophosphate aD-glucosyltransferase EC 2.4.1.67 1-aD-galactosyl -mio-inositol: raffinosagalactosyltransferase EC 2.4.1.71 UPD glucose: arylamine ND-glucosyltransferase EC 2.4.1.75 UDP galacturonate ß-D-galacturonosyltransferase EC 2.4.1.82 1-aD-galactosyl-myo-inositol: sucrose 6-aD-galactosyltransferase EC 2.4.1.90 UDPgalactose: N-acetyl-D-glucosamine 4-ß-galactosyltransferase EC 2.4.1.93 Inulin D-fructosyl-D-fructosyltransferase EC 2.4.1.99 Sucrose: 1 F-fructosyltransferase EC 2.4.1.100 1, 2-β-D-fructan: 1,2-β-D-fructan 1-β-D -fructosyltransferase EC 2.4.1.113 ADPglucose: protein 4-aD-glucosyltransferase EC 2.4.1.121 UDPglucose: indole-3-acetate ß-D-glucosyltransferase EC 2.4.1.125 Sucrose: 1,6-aD-glucan 3 (6) - -D -glucosyltransferase EC 2.4.1.140 Sucrose: 1, 6 (1, 3) -aD-glucan 6 (3) -aD-glucosyltransferase EC 2.4.1.161 1, 4-D-glucan: 1,4-aD-glucan 4- aD-glucosyltransferase EC 2.4.1.168 UDPglucose: xyloglucan 1,4-β-D-glucosyltransferase EC 2.4.1.169 UDP-D-xylose: xyloglucan 1,6-β-D-xylosyltransferase EC 2.4.1.183 UDP glucose: aD- (1 , 3) -glucan 3-aD-glucosyltransferase Of particular interest is EC 2.4.1.24 1, 4-aD-glucan: 1,4-aD-glucan (D-glucose) 6-aD-glucosyltransferase. A particular member of this enzyme is commercially available under the name Transglucosidase L-500. In addition to the glycosyltransferases described above, mutant mutant glycosyltransferases and / or glucosidases, examples of which are described in PCT application publication No. WO 97/21822, have been found to be equivalent to Canadian patent No. 2,165,041, and its US equivalent the US patent No. 5,716,812, all to S.G. Withers et al., Improve the tensile strength and appearance of fabrics, for example, reduce wrinkles in fabrics, increase shape retention and reduce shrinkage. The mutant forms of glucosyltransferases and / or glucosidases provide enzymatic binding, enzymatic entanglement and binding of enzymatic polymers, as described above in greater detail. The mutant glucosyltransferases and / or mutant glucosidases have only one nucleophilic amino acid at the active site of the enzyme, instead of two, such as non-mutated glucosyltransferases and / or non-mutated glucosidases, respectively. In other words, mutant glycosyltransferases and / or mutant glucosidases are formed in which one of the normal nucleophilic amino acids within the active site has been changed to a non-nucleophilic amino acid.
As a result, the mutant glucosyltransferases and / or mutant glucosidases only exhibit transferase activity; the mutant glucosyltransferases do not exhibit hydrolytic activity as well as the mutant glucosidases. Accordingly, unlike unmutated glucosyltransferases and / or unmutated glucosidases, the mutant glucosyltransferases and / or mutant glucosidases convert the oligosaccharides into a new class of polysaccharides without the harmful hydrolyzation of the new class of polysaccharides back to oligosaccharides or without that the water acts as a receptor for the transfer reaction. These mutant glucosyltransferases and / or mutant glucosidases can be extracted from plants, yeast, bacteria or other organisms. The DNA of the mutant glucosyltransferases and / or mutant glycosidases can be cloned and expressed in bacteria, yeast or fungi, and obtained in this manner. These mutant glucosyltransferases and / or mutant glucosidases can be incorporated into heavy duty liquid detergents, heavy duty granular detergents, fabric care compositions and the like. In addition to the utility of the mutant glucosyltransferases and / or mutant glucosidases in detergent compositions for laundry and / or fabric care, they can also be used in solutions for the treatment of fabrics in the textile process industry, and for the treatment of paper and pulp for paper. The novel features and properties of the mutated glycosyltransferases and / or the mutated glycosidases make them very suitable for use in laundry detergent and fabric care compositions because the absence of hydrolytic activity does not imply any loss in the tensile strength of the fabrics, even in the absence of donors in the transferase reaction. When mutant mutant glycosyltransferases and / or glucosidases are present in the compositions of the present invention, it is desirable that the concentration of saccharides in the compositions be in the range of about 0.01% to 30% by weight of the total composition, most preferably 1. % to 10% by weight of the total composition. In addition, the compositions of the present invention may have high molecular weight saccharides added to the compositions to obtain the benefits described above. Another class of enzymes that is of particular interest is xyloglucan transferases. A preferred xyloglucan transferase is endoxiloglucan transferase ("EXT"), which is described in J. Plant Res. 108, 137-148, 1995 by Nishitani, Kagoma University, and now called "EXGT" in Int. Review of Cytology , vol. 173, p. 157, 1997 by Nishitani, University of Kagoma. EXT also describes J. Biol. Chem. 267, 21058-21064, 1992 by Nishitani et al. Like the mutant glucosyltransferases described above, this endoxiloglucan transferase improves the tensile strength and appearance of fabrics, for example, it reduces wrinkles in fabrics, increases shape retention and reduces shrinkage. Endoxiloglucan transferase binds cellulose fibrils. These binding properties of the enzyme on the cellulose fibrils provide the benefits mentioned above. The endoxiloglucanotransferase is responsible for re-joining intermicrofibrillary xyloglucan chains, the xyloglucan chains between cellulose microfibrils during the formation of plant cell walls. By rejoining the cellulosic microfibrils through xyloglucan bonds, the cellulose structure acquires improved fiber strength. Since the structure of the fabrics is of cellulosic nature, the enzyme has a binding activity in the microfibrils. Also, the benefits of shape retention, anti-shrinkage and anti-wrinkle can be explained by the binding properties of the enzyme. The endoxiloglucan transferase is different in activity from the xyloglucan endotransglucosylase ("XET transferase"), which is described in WO 97/23683 of Novo Nordisk A / S, in Biochem. J. (1992) 282, 821-828 by Fry et al. And in Plant J. (1993) 3 (5), 691-700. The difference is that the xyloglucan endotransglucosylase shows both transferase activity and hydrolase (hydrolytic) activity. In contrast, endoxiloglucan transferase only shows transferase activity. The endoxiloglucan transferase shows no hydrolase activity. Consequently, unlike the xyloglucan endotransglucosilasa, the endoxiloglucan transferase converts oligosaccharides into a new class of polysaccharides without the harmful hydrolyzation of the new class of polysaccharides back to oligosaccharides. In addition, endoxiloglucan transferase exhibits stringent donor specificity for high molecular weight xyloglucan polymers and does not act on low molecular weight xyloglucan oligomers. Preferably, the endoxiloglucan transferase exhibits stringent donor specificity for xyloglucan polymers having molecular weights of at least 10,000. The novel characteristics and properties of endoxiloglucan transferase make it highly suitable for use in laundry detergent and care compositions. fabrics because the absence of hydrolytic activity does not imply any loss in the tensile strength of the fabrics, even in the absence of donors in the transferase reaction. In addition, lower levels of substrate donor can be used. Without wishing to be limited, it is believed that high benefits can be obtained even in the absence of a donor substrate if the endoxiloglucan transferase uses xyloglucans from the primary wall of the cotton fiber within the fabrics. Endoxiloglucan transferase can be extracted from plants and other organisms. Endoxiloglucan transferase can be obtained from a large number of plants, including, but not limited to, A. thaliana and V. Angularis. Alternatively, the DNA of the enzyme can be cloned and expressed in bacteria, yeast or fungi, and obtained in this manner. Endoxiloglucan transferase can be incorporated into heavy duty liquid detergents, heavy duty granular detergents, fabric care compositions and the like. In addition to its utility in detergent compositions for laundry and fabric care, endoxiloglucan transferase can also be used in solutions for the treatment of fabrics in the textile process industry, and for the treatment of paper and paper pulp. When the endoxiloglucan transferase is present in the compositions of the present invention, it is desirable that the concentration of xyloglucan in the compositions be in the range of about 0.01% to 30% by weight of the total composition, most preferably 1% to 10% by weight of the total composition. In addition, the compositions of the present invention can have high molecular weight xyloglucan polymers added to the compositions to obtain the benefits described in the preceding paragraphs. Thus, when transferase is a xyloglucan transferase, such as endoxiloglucan transferase, the endoxiloglucan transferase preferably exhibits greater transferase activity than hydrolase (hydrolytic) and / or xyloglucan transferase preferably exhibits stringent donor specificity for high molecular weight xyloglucan polymers and does not act on low molecular weight xyloglucan oligomers, most preferably, xyloglucan transferase exhibits strict donor specificity for xyloglucan polymers having molecular weights of at least 10 000. Yet another enzyme of particular interest is cyclomaltodextrin glucanotransferase ("CGT-asa") (EC 2.4.1.19), which is commercially available from Amano and Novo Nordisk A / S . The covalent linking of carbohydrates, oligo- and polysaccharides to cotton surfaces, such as fabrics, with a transferase provides benefits such as anti-wrinkling, color maintenance, dye fixation and dirt repelling. The covalent binding of glucose units to the cellulose surface against a physical absorption of polymers, which are produced by the transferase in situ (or others), makes the indicated benefits last. Cyclomaltodextrin glucanotransferase is a transferase that exhibits several different actions in starch. It is produced from starch a, ß and? Cyclodextrins, hydrolyses starch and interlaces starch. In these types of reactions, sugars are both donors and receptors for the transferase reaction. Until now, it was not clear if these transferase enzymes could covalently bind sugar units to cotton. Surprisingly, it has been found that cyclomaltodextrin glucanotransferase can covalently bind a-cyclodextrin glucose units to the cotton surfaces of fabrics at the non-reducing end of the cellulose polymers. Consequently, the cyclomaltodextine glucanotransferase has the ability to make the benefits described above more durable. As described above, it is known that the covalent bonding of cellulose polymers with entanglement agents provides benefits to the fabrics, such as anti-wrinkle benefits, but the anti-wrinkle benefits can also be obtained by a physical absorption of polymers on the surface. of cotton. This physical absorption of polymers on the cotton surface can now be made more durable because one of the polymer units is covalently bonded to the cotton surface by the action of cyclomaltodextrin glucanotransferase. Since these more durable benefits are produced enzymatically, the covalent bond occurs at a much lower temperature, and thus much lower temperatures are possible in the wash cycle compared to conventional wash cycles. In addition, conventional entanglement chemicals (some of which are potentially toxic) that are used in the textile industry are not applicable at the lowest temperatures in the wash cycle. Other benefits, such as dye fixation and improved dirt release, are obtained through the covalent incorporation of cationic or anionic glucose units to the cotton surface. Accordingly, the use of cyclomaltodextrin glucanotransferase in laundry detergent and fabric care compositions provides improved benefits to anti-wrinkle fabrics, form retention, anti-shrinkage, dye fixation, dirt repellency and tensile strength. Cyclomaltodextrin glucanotransferase can be incorporated into heavy duty liquid detergents, heavy duty granular detergents, fabric care compositions and the like. In addition to its utility in detergent compositions for laundry and fabric care, cyclomaltodextrin glucanotransferase can also be used in solutions for the treatment of fabrics in the textile process industry, and for the treatment of paper and paper pulp. When the cyclomaltodextrin glucanotransferase is present in the compositions of the present invention, it is desirable that the concentration of starch in the compositions be in the range of about 0.01% to 30% by weight of the total composition, most preferably 1% to 10% by weight of the total composition. In addition, the compositions of the present invention can have cyclodextrins or types of starch and sucrose added to the compositions to obtain the benefits described above. Another group of enzymes that is of particular interest are glucanosacarases, of which one example is dextranosacarase (EC 2.4.1.5), a glucosyltransferase. Other glucanosacarases that are suitable for use in the compositions described herein include, but are not limited to, various dextranaserases, alternanosaccharides. Alternatively, levanosacarase which is commercially available from Genencor can be used.
Dextranosacarase enzymes can be obtained from any suitable source known in the art, and are used in conjunction with suitable substrates (sucrose +/- maltose). Dextranosacarase catalyzes glycosyl residue transfer reactions from one polysaccharide to another. As a result of the dextranosecarase reactions, high molecular weight dextrans are produced on the surfaces of the fabrics. In dextran, glucose residues are linked by 1-6- bonds. The modification of cotton fibers with carbohydrates, oligo- and polysaccharides, provides benefits such as anti-creasing, color maintenance, colorant fixation and dirt repelling. The durability of these benefits may require the covalent linkage of the oligosaccharides. It has been found that dextranosacarase can bind oligosaccharides to cellulose polymers in cotton. As a result of this binding by means of the transfer reactions catalyzed by dextransucrase, improved fabric appearance benefits are provided, i.e., improved anti-wrinkle benefits, form retention, anti-shrinkage, colorant fixation, dirt repellency and resistance to tension. When the reaction products are bound (may or may not be a covalent bond) to cotton, they modify the surface of the cotton and the fibrils, which in turn provides the fabric care benefits described above. Dextranosacarase with sucrose also provides improved whiteness benefits (colorants from other colored garments are not deposited on white fabrics). The combination of dextranosecarase / sucrose forms high molecular weight dextran (and smaller oligomers when other saccharides such as maltose, cellobiose, etc. are present). In addition, it has been found that the efficiency of deposition of reaction products on the fabrics is high, and that the reaction products are not all washed out in the next wash cycle. Glucanase can be incorporated into heavy duty liquid detergents, heavy duty granular detergents, fabric care compositions, and the like. In addition to their utility in detergent compositions for laundry and fabric care, glucanosarases can also be used in solutions for the treatment of fabrics in the textile process industry, and for the treatment of paper and paper pulp. When glucanosacarase is present in the compositions of the present invention, it is desirable that the concentration on substrate (typically sucrose or other disaccharides) of the compositions is on the scale of about 0.01% to 30% by weight of the total composition, very preferably 1% to 10% by weight of the total composition. In addition, the compositions of the present invention may have smaller polysaccharides such as sucrose, maltose, maltodextrins, celosaccharides and types of starch added to the compositions to obtain the benefits described above. These transferases are preferably incorporated in the compositions according to the invention at a level of from 0.0001% to 10%, most preferably from 0.0005% to 5%, very much preferably from 0.001% to 1% pure enzyme by weight of the total composition . The fabric care and / or cleaning benefits can be obtained by the laundry and / or fabric care compositions of the present invention in the presence or absence of the corresponding natural substrate. In general, the first part of the name of the enzyme indicates the substrate for the reaction of the enzyme, and the second part is the receptor to which the group is transferred. The substrate of the transferase enzyme can be the fabric itself, spots and / or dirt, added in any treatment including pre-treatment or post-treatment from the textile industry and / or any washing and / or fabric care process, and / or adding together with the composition that contains transferase. Examples of substrates for some of the transferases listed above are: S-adenosyl-L-methionine, 5,10-methylenetetrahydrofolate or formiminotetrahydrofolate (transfer of hydroxymethyl or formyl groups to glycine), formaldehyde, acetyl Co A, methyl-a, w-diamine, palmityl Co A, geranoyl di phosphate. In particular, the substrate for the aminoacyl transferases is an amino-containing compound such as an amino acid, a di / tri / polypeptide and / or a protein. Among the glycosyltransferases, although the transfer group is a glucosyl residue, the specific points of the substrate for each enzyme are derived from the first part of the name. Especially for glycosyltransferases, the natural substrate could be any alpha-glucosyl saccharide chosen from amylaceous substances in a dimer, oligomer and / or polymer. The examples are preferably different forms of starch (gelatinized, liquefied, solubilized), hydrolyzed partial starch, most preferably malto-oligosaccharides and most preferably maltose. Of interest are also substituted starch / sugar substrates, which contain substitution by methylation and carboxylation. Alternatively, the following substrates can be used for the aforementioned glucosyltransferases: dextrins, sucrose, raffinose, fructosyl polymers, UDP glucose, xyloglucan, GDP glucose, arylamine, UDP galacturonate, ADP glucose, indole-3-acetate, aD-glucans, UDP -xilane. The transferase substrates are preferably incorporated into the compositions according to the invention at a level of from 0.01% to 30%, most preferably from 0.1% to 20%, more preferably from 1% to 10% by weight of the total composition. The enzymes mentioned above may have any suitable origin, such as vegetable, animal, bacterial, fungal and yeast. The origin can also be mesophilic or extremophilic (psychrophilic, psychrotrophic, thermophilic, barophilic, alkalophilic, acidophilic, halogenophilic, etc.). Purified or unpurified forms of these enzymes can be used. Currently, it is a common practice to modify wild-type enzymes by protein / gene engineering techniques to optimize their efficiency of performance in the cleaning compositions of the invention. For example, the variants can be designed in such a way that the compatibility of the enzyme with the ingredients commonly found in said compositions is increased. Alternatively, the variant can be designed in such a way that the optimum pH, stability in bleach and / or chelator, catalytic activity and the like, of the enzyme variant are worked to suit the particular fabric conditioning and / or cleaning application. In particular, attention must be focused on amino acids sensitive to oxidation in the case of bleach stability, and on surface charges for compatibility with surfactants. The isoelectric point of said enzymes can be modified by the replacement of some charged amino acids, for example, an increase in the isoelectric point can help improve compatibility with anionic surfactants. The stability of the enzymes can be further increased by the creation, for example, of additional salt bridges and promoting calcium binding sites to increase chelator stability.

The pump mechanism comprises a pumping chamber, of substantially fixed volume, having an opening at its inner end.
A pump rod having a piston at one of its ends arranged to move reciprocally in the pumping chamber is located within the pump chamber. The pump rod has a passage through it, with a dispensing outlet at the outer end of the passage, and an axial entry port, located inwardly thereof. The container and the pump mechanism may be constructed of any conventional material used in the manufacture of the pump spray dispensers, including, but not limited to: polyethylene, polypropylene, polyethylene terephthalate. mixtures of polyethylene, vinyl acetate and elastomeric rubber. A preferred container is made of clear polyethylene terephthalate. Other materials may include stainless steel. A more complete description of the dispensing devices available in commerce appears in U.S. Patent No. 4,895,279, Schultz, issued January 23, 1990; 4,735,347, Schultz et al., Issued April 5, 1988; and 4,274,560, by Carter, issued on June 23, 1981, all these references are hereby incorporated by reference to them. It is highly preferable that the sprayer dispenser be a manually operated trigger dispenser with trigger. Said trigger sprinkler dispenser comprises a container and a trigger, both of which may be constructed of any conventional material used in the manufacture of the trigger sprinkler dispensers, including, but not limited to: polyethylene, polypropylene, polyacetal, polycarbonate, terephthalate polyethylene, polyvinyl chloride, polystyrene, polyethylene blends, vinyl acetate and elastomeric rubber. Other materials may include: stainless steel and glass. A preferred container is made of clear polyethylene terephthalate. The trigger sprinkler dispenser does not incorporate a propellant gas in the odor absorbing composition, and preferably does not include those that froth the odor absorbing composition. The trigger sprinkler dispenser of the present typically is one that acts on a discrete amount of the odor absorbing composition itself, typically by means of a piston or a collapsible bellows, which moves the composition through a nozzle to create a spray of thin liquid. Said trigger sprinkler dispenser typically comprises a pump chamber having a piston or a bellows that is movable in a limited stroke, in response to the trigger, to vary the volume of the pump chamber. This pumping chamber or bellows chamber collects and contains the product to be dispensed. The trigger sprinkler dispenser typically has an outlet check valve to block communication and fluid flow through the nozzle, and which responds to pressure within the chamber. For trigger sprinklers, of the piston type, when the trigger is pressed, it acts on the fluid in the chamber and the spring, increasing the pressure on the fluid. For the bellows sprinkler dispenser, when the bellows is compressed the pressure on the fluid increases. The increase in fluid pressure in any of the trigger sprinkler dispensers, acts to open the outlet check valve, from the top. The upper valve allows the product to be forced through the whirl chamber and out through the nozzle to form a discharge pattern. An adjustable nozzle cap can be used to vary the pattern of the dispensed fluid. For the piston spray dispenser, when the trigger is released, the spring acts on the piston to return it to its original position. For the bellows sprinkler dispenser, the bellows acts as a spring to return it to its original position. This action causes a vacuum in the camera. The fluid that responds acts to close the outlet valve, at the same time that it opens the inlet valve, which carries product upwards, to the chamber, from the reservoir.
