Definitions

  • the present invention relates to detergent compositions comprising an enzymatic system comprising a mannanase, a xyloglucanase and a pectate lyase.
  • detergent compositions include nowadays a complex combination of active ingredients which fulfil certain specific needs.
  • current detergent formulations generally include surfactants and detergent enzymes providing cleaning and fabric care benefits. Removal of stains stemming from plants, wood, mould-clay based soil, muddy soils, and fruits is one of today's toughest cleaning tasks; especially with the trend toward low wash temperatures. These stains typically contain complex mixtures of fibrous material based mainly on carbohydrates and their derivatives : fibres and cell wall components.
  • Plant based soils are additionally accompanied with amylose, sugars and their derivatives.
  • Food soils are often difficult to remove effectively from a soiled substrate.
  • Highly coloured or "dried-on" soils derived from fruit and/or vegetable juices are particularly challenging to remove. Specific examples of such soils would include orange juice, tomato juice, banana, mango or broccoli soils.
  • pectin polymers are important constituents of plant cell walls.
  • Pectin is a hetero-polysaccharide with a backbone composed of alternating homogalacturonan (smooth regions) and rhamnogalacturonan (hairy regions). The smooth regions are linear polymers of 1 ,4-linked alpha-D-galacturonic acid.
  • the galacturonic acid residues can be methyl-esterified on the carboxyl group to a varying degree, usually in a non- random fashion with blocks of polygalacturonic acid being completely methyl- esterified.
  • the substrates on which pectin containing stains are commonly found can be fabrics, dishware or hard surfaces.
  • amylase enzymes have long been recognised in detergent compositions to provide the removal of starchy food residues or starchy films from dishware or hard surfaces or to provide cleaning performance on starchy soils as well as other soils typically encountered in laundry applications.
  • Protease enzymes have long been recognised in detergent compositions to provide the removal of proteinaceous food residues from dishware, hard surfaces or to provide cleaning performance on proteinaceous soils as well as other soils typically encountered in laundry applications.
  • cellulase is also well-known in the art. This activity in particular on fabrics provides a cleaning, rejuvenation, softening and generally improved handfeel characteristics to the fabric structure.
  • lipolytic enzyme e.g. lipase
  • Pectin degrading enzymes are known to provide soil/stain removal benefits when used in washing and cleaning operations, specifically to provide the removal of a broad range of plant and fruit based stains and enhance the realistic item cleaning profile of the detergent compositions. Indeed, removal of stains stemming from plants, wood, mould-clay based soil and fruits is one of today's toughest cleaning task; in particular with the trends to move to low wash temperatures. Food soils are often difficult to remove effectively from a soiled substrate. Highly coloured or "dried-on" soils derived from fruit and/or vegetable juices are particularly challenging to remove. Specific examples of such soils would include orange juice, tomato juice, banana, mango or broccoli soils.
  • Xyloglucan specific endoglucanases having a high xyloglucan-degrading activity may be of particular use for degradations of cell wall material having a high xyloglucan content, for instance in the wine and fruit industries, for pectin - extraction and for removal of hemicelluloses from textile fibers. Furthermore, it has been recognised that such specific xyloglucan enzymes removes the xyloglucan without altering the cellulose. The use of such xyloglucan specific endoglucanases in detergent compositions has only been recently discovered as described in the co-pending international patent application PCT/US98/09126, internationally filed by Procter and Gamble on May 5, 1998.
  • Mannanase enzymes are known for their hydrolytic activity on mannans-containing stains/soils such as food and/or cosmetic stains/soils.
  • Food and cosmetic stains/soils represent an imporatnt part of consumer relevant stains/soils and often comprise additives such as thickener / stabiliser agents.
  • hydrocolloids gums and emulsifiers are commonly used additives.
  • detergent compositions comprising a specific enzyme system comprising a mannanase, a pectate lyase and/or a xyloglucanase.
  • Mannanases have been identified in several Bacillus organisms. For example, Talbot et al., Appl. Environ. Microbiol., vol. 56, No. 11 , pp. 3505-3510 (1990) describes a ⁇ -mannanase derived from Bacillus stearothermophilus in dimer form having a MW of 162 kDa and an optimum pH of 5.5-7.5. Mendoza et al., World J. Micobio. Boitech., vol. 10, no. 5, pp.
  • J0304706 discloses a ⁇ -mannanase derived from Bacillus sp. having a MW of 37+/- 3kDa measured by gel filtration, an optimum pH of 8-10 and a pi of 5.3-5.4.
  • J63056289 describes the production of an alkaline, thermostable ⁇ -mannase, which hydrolyses ⁇ -1 ,4-D-mannopyranoside bonds of e.g. mannans and produces manno:oligo:saccharides.
  • J63036774 relates to a Bacillus micro-organism FERM P-8856 which produces ⁇ - mannanase and ⁇ -mannosidase, at an alkaline pH.
  • W091/18974 describes an hemicellulase such as a glucanase, xylanase or mannanase, active at extreme pH and temperature and the production thereof.
  • W094/25576 describes an enzyme exhibiting a mannanase activity derived from Aspergillus aculeatus CBS 101.43, that might be used for various purposes for which degradation or modification of plant or algae cell wall material is desired.
  • W093/24622 discloses a mannanase isolated from T choderma reesie for bleaching lignocellulosic pulps.
  • Pectin degrading enzymes as detergent enzymes are described in EP-A-751 990 and in co-pending patent applications PCT/US96/12963, PCT/US96/12962, PCT/US96/12959, PCT/US96/12960 and PCT/US96/12691 ; all filed on August 09, 1996.
  • W095/35362 discloses cleaning compositions containing plant cell wall degrading enzymes having a pectinase and/or hemicellulase and optionally cellulase activity for the removal of stains from vegetable origin.
  • Xyloglucan specific endoglucanases have been identified in various plants, see for example, the disclosure of Fry et al., Biochem. J. (1992), Vol.
  • a xyloglucan specific endoglucanases in microorganisms is described in WO 94/14953.
  • "endoglucanases having a high xyloglucan-degrading activity may be of particular use for degradations of cell wall material having a high xyloglucan content, for instance in the wine and fruit industry, for pectin-extraction and for removal of hemicelluloses from textile fibres”.
  • Specifically referred to for this last property is the use of these enzymes to manufacture textile fibers: "The hemicellulose like xyloglucan has to be removed from plant fibers like cotton, flax, hemp and jute before these can be used for textiles.
  • endoglucanase of type II i.e., the xyloglucan- specific enzymes
  • the endoglucanases of the invention and analogous thereof may be used to treat cellulose fibres or cellulose-fibre rich material.
  • the endoglucanases may e.g. be used in the paper industry to improve the drainage of pulp, and to treat fabrics such as cotton fabrics, to give a more smooth fabric.”
  • the present invention relates to detergent compositions, including laundry, dishwashing, hard surface cleaner compositions, comprising a mannanase, a pectate lyase and a xyloglucanase, for superior cleaning performance, i.e. superior stain removal, dingy cleaning and whiteness maintenance.
  • the detergent compositions of the present invention comprise as essential elements a mannanase, a pectate lyase and a xyloglucanase. It has been surprisingly found that such compositions provide superior cleaning performance, i.e. superior stain removal, dingy cleaning and whiteness maintenance.
  • the polymeric, branched nature of these substrates is believed to attract and hold stain/soil components to fabric, dish, and/or hard surfaces. Attacking these substrates with said specific mixture of enzymes provides overall superior removal of soils/stains, especially food-based soils and stains, than is otherwise obtained with the individual enzyme alone.
  • cotton fibers retain some portion of the primary cell wall.
  • the pectins and xyloglucans present in this residual primary cell wall layer present a preferred binding site for the hydrocolloid gums found in a number of prepared foods and personal and beauty care products such as shampoos, body lotions, and make-up. When such materials contact cotton fabrics they are difficult to remove with standard detergents.
  • the enzyme mixture contemplated in this invention is effective at removing such stains because the Pectate Lyase and Xyloglucanase aid in removal of the residual primary cell wall components of the cotton garment while the Mannanase serves to break down the hydrocolloid gums found in the soils/stains themselves.

  • Mannanases (EC 3.2.1.78) constitute a group of polysaccharases which degrade mannans and denote enzymes which are capable of cleaving polyose chains contaning mannose units, i.e. are capable of cleaving glycosidic bonds in mannans, glucomannans, galactomannans and galactogluco-mannans.
  • Mannans are polysaccharides having a backbone composed of ⁇ -1 ,4- linked mannose; glucomannans are polysaccharides having a backbone or more or less regularly alternating ⁇ -1 ,4 linked mannose and glucose; galactomannans and galactoglucomannans are mannans and glucomannans with ⁇ -1 ,6 linked galactose sidebranches. These compounds may be acetylated. The degradation of galactomannans and galactoglucomannans is facilitated by full or partial removal of the galactose sidebranches.
  • acetylated mannans, glucomannans, galactomannans and galactoglucomannans is facilitated by full or partial deacetylation.
  • Acetyl groups can be removed by alkali or by mannan acetylesterases.
  • the oligomers which are released from the mannanases or by a combination of mannanases and ⁇ - galactosidase and/or mannan acetyl esterases can be further degraded to release free maltose by ⁇ -mannosidase and/or ⁇ -glucosidase.
