Definitions

  • the present invention relates to laundry detergent compositions, comprising a saccharide gum degrading enzyme.
  • Detergent compositions include nowadays a complex combination of active ingredients which fulfill certain specific needs.
  • current detergent formulations generally include detergent enzymes providing cleaning and fabric care benefits and more specifically cellulase and amylase enzymes.
  • cellulytic enzymes i.e. cellulases
  • the efficiency of cellulase is one in which cellulosic fibres or substrates are hydrolysed by the cellulase and depending on the particular function of the cellulase, which can be endo- or exo- cellulase and the respective hemicellulases.
  • the cellulose structures are depolymerized or cleaved into smaller and thereby more soluble or dispersible fractions. This activity in particular on fabrics provides a cleaning, rejuvenation, softening and generally improved handfeel characteristics to the fabric structure.
  • Amylases are known in the art to provide stain removal performance benefits on naturally present or added starch containing food stains/soils or added as a finishing agent.
  • Food stains/soils represents the majority of consumer relevant stains/soils and often comprise food additives.
  • Neutraceuticals, acidulants, antioxidants, preservatives, sweeteners, enzymes, thickener / stabiliser agents such as hydrocolloids and emulsifiers are commonly used food additives.
  • the consumer demand for reductions in fat and calories is driving growth in texturing agents as fat replacers.
  • the market for hydrocolloid texturing / stabiliser agent also called food gums is expected to grow about 4% a year, xanthan gum growth should register gains of 6% to 8%/year and carrageenan about 3%/year (Chemical week, June 19 (1996) pp32-34).
  • glycol denotes a group of industrially useful polysaccharides (long chain polymer) or their derivatives that hydrate in hot or cold water to from viscous solutions, dispersions or gels. Gums are classified as natural and modified. Natural gums include seaweed extracts, plant extrudates, gums from seed or root, and gums obtained by microbial fermentation. Modified (semisynthetic) gums include cellulose and starch derivatives and certain synthetic gums such as low methoxyl pectin, propylene glycol alginate, and carboxymethyl and hydropropyl guar gum (Gums in Encyclopedia Chemical Technology 4 th Ed. Vol. 12, pp842-862, J. Baird, Kelco division of Merck).
  • xanthan gum E 415, CEE number
  • gellan gum E416
  • guar gum E412
  • locust bean E410
  • tragacanth E413
  • guar gum is often used in foods as a thickener and a binder of free water in sauces and salad dressings.
  • Guar gum is also used as a binder of free water and stabiliser in ice cream and frozen desserts.
  • Free water in ice cream mix causes a grainy texture, ice crystals, poor meltdown properties and poor heat-shock resistance in the finished ice cream.
  • the incorporation of a stabiliser containing guar gum in quantities up to about 0.3% of the ice cream mix yields a smooth-textured, chewy product with slow-melting down properties and good heat shock resistance. It is also particularly suitable for flash pasteurisation because of its rapid hydration properties.
  • Other foods that can be stabilised with guar gum because of its ability to bind water, are frozen foods, cheeses, pie fillings, icings and pet foods.
  • algin gums are known to be used in sherbet, canned and fabricated food, tragacanth gums used in salad dressings, xanthan for dairy products and beverages. Gellans are found in icing, frosting and dairy products and locust bean and agar in ice creams.
  • laundry detergent compositions which provide excellent overall cleaning performance. Accordingly it is an object of the present invention to provide a laundry detergent composition which delivers superior cleaning and whiteness performance benefits, especially excellent food stain/soil removal, dingy cleaning and whiteness maintenance.
  • laundry detergent compositions comprising a saccharide gum degrading enzyme.
  • the laundry detergent composition of the present invention comprising a saccharide gum degrading enzyme, provides excellent food stain/soil removal, dingy cleaning and whiteness maintenance resulting from the hydrolysis of the food saccharide gums binding food or clays stains/soils to cotton fabrics. It has been further found that the performance of the laundry detergent compositions of the present invention is enhanced by the addition of selected surfactants, another enzyme, a builder and/or a bleach system.
  • GB2-169-393 describes a method for removing cellulose contaminant and other vegetable contaminants from fabrics, using the conventional machinery and equipment of dye-house and finishing mills by treatment with an enzymatic preparation containing cellulolytic and pectinolytic enzymes that allow for a reduction of H 2 SO 4 concentration below 2% during fabric carbonisation.
  • WO96/06532 relates to a composition capable of killing or inhibiting growing microbial cells by means of a basic protein or peptide of biological origin, e.g. protamine or protamine sulphate.
  • these composition furhter comprise an oxidoreductase or cell-wall degrading enzyme such as an endoglycosidase type II, a lysozyme and/or a chitinase.
  • WO95/35362 describes to cleaning compositions, including laundry, dishwashing and especially household cleaning compositions, comprising cell wall degrading enzymes having pectinases and/or hemicellulases and optionally cellulases. These compositions are particularly suitable for removing stains of vegetable origin and soil and dirt having a similar structure. These plant cell wall degrading enzymes degrade the structural components of the plant cell walls such as the structured polysaccharides (cellulose, hemicellulose, pectins) and encompass cellulolytic, pectin degrading and hemicellulose degrading enzymes. A large number of plant cell wall degrading enzyme exist.
  • Cellulolytic enzymes have divided into three classes : endoglucanases, exoglucanases or cellobiohydrolases and ⁇ -glucosidases.
  • a large number of enzymes are known to degrade pectins; examples are pectin esterase, pectin lyase, pectate lyase, and endo- or exo-polygalacturonase.
  • pectin esterase examples are pectin esterase, pectin lyase, pectate lyase, and endo- or exo-polygalacturonase.
  • enzymes degrading hairy regions such as rhamnogalacturonase and accessory enzymes have also been found.
  • a multitude of enzymes is available to degrade the hemicellulose structures such as xylanase, galactanase, arabinase, lichenase and mannanase.
  • saccharide gum degrading enzymes for excellent cleaning performance on cotton fabrics in laundry detergent compositions, has never been previously recognised.
  • the present invention relates to laundry detergent compositions comprising a saccharide gum degrading enzyme, providing excellent cleaning performance on cotton fibers, especially food stain/soil removal, dingy cleaning and whiteness maintenance benefits.
  • An essential component of the laundry detergent compositions of the present invention is a saccharide gum degrading enzyme. These enzymes are able to hydrolyse non starch, non cellulose, food polysaccharides having a viscosity higher than 800 cps at 1% solution (Measured in water at 25°C, Brookfield Synchro-Lectic viscosimeter at 20 rpm).
  • laundry detergent compositions of the present invention provide excellent cleaning and whiteness performance and especially significant food stain/soil removal benefits and dingy stain/soil cleaning.
  • saccharide gum degrading enzymes hydrolyse the food gums additives present in food stains/soils, that glue the stains/soils to the cotton fibres.
  • these non starch, non cellulose food polysaccharides have a high affinity for the cotton fibres thereby binding the stains/soils to the fabric. The hydrolysis of these non starch, non cellulose food polysaccharides release therefore the stains/soils from the cotton textile.
  • the laundry detergent composition of the present invention provide significant dingy cleaning and whiteness maintenance.
  • the saccharides being breakdown products of the partial cleaning of these food stains/soils by current detergent formulations, redeposit on the fabric and react with particulate soils such as clay compounds, leading to the dinginess of the cotton fabric.
  • the saccharide gum degrading enzymes of the present invention hydrolyse the film of saccharides deposited onto the fabrics, thereby preventing the flocculation of these compounds with particulate soils.
  • the enzymatic action of the saccharide gum degrading enzymes of the present invention renders the food and dingy stains/soils more accessible to the other detergent components of the laundry detergent composition.
  • the performance of the laundry detergent composition of the present invention is enhanced by the combination with a selected surfactant, another enzyme, a builder and/or a bleach system.
  • the enzymes of the present invention have a main or side activity on the non starch, non cellulose, food polysaccharides having a viscosity higher than 800cps at 1% solution, such as agar, algin, karawa, tragacanth, guar gum, locus beam, xathan and/or mixtures thereof.
  • food polysaccharides having a viscosity higher than 800cps at 1% solution, such as agar, algin, karawa, tragacanth, guar gum, locus beam, xathan and/or mixtures thereof.
