Definitions

  • the present invention relates to laundry detergent and/or fabric care compositions comprising a transferase.
  • Laundry detergent and/or fabric care compositions are well-known in the art and extensively represented in the market place.
  • Laundry detergent compositions include nowadays a complex combination of active ingredients which fulfil certain specific needs : a surfactant system, enzymes providing cleaning and fabric care benefits, bleaching agents, a builder system, suds suppressors, soil-suspending agents, soil-release agents, optical brighteners, softening agents, dispersants, dye transfer inhibition compounds, abrasives, bactericides, perfumes, and their overall performance has indeed improved over the years.
  • Fabric softening compositions impart several desirable properties to treated garments including softness and static control. Fabric softness of laundered garments is typically achieved by delivering a quaternary ammonium compound to the surface of the fabric.
  • Durable press garments include those garments which resist wrinkling of the fabric both during wear and during the laundering process.
  • Durable press garments can greatly decrease the hand work associated with laundering by eliminating ironing or reducing ironing time sometimes necessary to prevent wrinkling of the garment.
  • the fabric's ability to resist wrinkling is reduced over time as the garment is repeatedly worn and laundered.
  • coloured garments have a tendency to wear and show appearance losses. A portion of this colour loss may be attributed to abrasion in the laundering process, particularly in automatic washing machines and automatic laundry dryers.
  • laundry detergent composition and/or fabric care composition which can provide, refurbish or restore tensile strength, anti- wrinkle, anti-bobbling and anti-shrinkage properties to fabrics, as well as provide static control, fabric softness, colour appearance and fabric anti-wear properties and benefits.

These so-produced saccharides are used in the pharmaceutical field.
  • Microbial transglutaminases their production and their use in a variety of industrial purposes, including gelling of proteins, improvement of baking quality of flour, producing paste type food material from protein, fat and water, preparation of cheese from milk concentrate, binding of chopped meat, improvement of taste and texture of food proteins, casein finishing in leather processing, shoe shine, etc. have been described in WO96/06931.
  • JP 7-107971 relates to a micro-organism belonging to the genus Bacillus and having the capacity to produce an alkali resistant cyclodextrin glucanotransferase.
  • Said enzyme can be used in dishwashing applications wherein it demonstrates decomposition and removal of food soils and the produced cyclodextrin plays as a masking, de-odorizing agent.
  • said alkali resistant cyclodextrin glucanotransferase improves the cleaning capabilities of said compositions by improving the sudsing properties and stimulating the emulsification of the soiling.
  • Dishwashing detergent compositions containing cyclodextrin glucanotransferase with cleaning benefits and deodorising effect are described in JP 7-109488.
  • WO 97/23683 relates to the use of xyloglucan endotransglycosylase (XET) to provide strength and/or shape-retention and/or anti- wrinkling properties to cellulosic material.

  • the enzyme improves the properties of garments by binding functional groups like methyl, hydroxymethyl, formyl, carboxyl, aldehyde, ketone, acyl, amino and phosphorous functional groups and/or transferring glycosyl residues to the garment surface.
  • the improved garments properties include tensile strength, anti-wrinkle, anti-bobbling and anti-shrinkage properties to fabrics, static control, fabric softness, colour appearance and fabric anti-wear properties and benefits.
  • the transferase level is high and the substrate concentration is low, the functional groups are transferred to water molecules providing cleaning benefits.

As a result of the enzymatic activity, oligosaccharides are converted into a new class of polysaccharides. It has been surprisingly found that glycosyltransferases improve the tensile strength and appearance of fabrics, e.g. reduce fabric wrinkles.
  • oligosaccharides are bound to the cellulose polymers of cotton fabrics resulting in improved tensile strength and demonstrating appearance benefits especially after multiple wash cycles.
  • glycosyltransferase activity is believed to have four potential modes of action providing fabric care benefits :

  • the novel characteristics and properties of the mutated glycosyltransferases and/or the mutated glycosidases make them highly suitable for use in laundry detergent and fabric care compositions because the absence of hydrolytic activity implies no loss in tensile strength of fabrics, even in the absence of donors in the transferase reaction.
  • mutant glycosyltransferases and or mutant glycosidases are present in the compositions of the present invention, it is desirable that the saccharide concentration in the compositions is in the range of from about 0.01% to 30% by weight of the total composition, more preferably, 1% to 10% by weight of the total composition.

  • endoxyloglucan transferase exhibits strict donor specificity for xyloglucan polymers having molecular weights of at least 10,000.
  • endoxyloglucan transferase makes it highly suitable for use in laundry detergent and fabric care compositions because the absence of hydrolytic activity implies no loss in tensile strength of fabrics, even in the absence of donors in the transferase reaction. Furthermore, lower levels of substrate donor can be used. Without desiring to be limited, it is believed that high benefits can be obtained even in the absence of a donor substrate if the endoxyloglucan transferase uses xyloglucans of the primary wall of the cotton fiber within fabrics.

  • CCT-ase cyclomaltodextrin glucanotransferase
  • Cyclomaltodextrin glucanotransferase is a transferase that exhibits several different actions on starch. It produces from starch ⁇ , ⁇ , and ⁇ cyclodextrins, hydrolyzes starch and cross links starch. In these types of reactions, ⁇ sugars are both donor and acceptor for the transferase reaction. Up to now, it was not clear if these transferase enzymes could covalently link sugar units to cotton.
  • cyclomaltodextrin glucanotransferase can covalently link glucose units from ⁇ -cyclodextrine to the cotton surfaces of fabrics at the non-reducing end of the cellulose polymers. Accordingly, cyclomaltodextrin glucanotransferase has the ability to make the benefits discussed above more durable.
  • covalently linking cellulose polymers with cross-linking agents delivers benefits to fabrics, such as anti-wrinkle benefits, but anti- wrinkle benefits can also be obtained by a physical absorption of polymers on the cotton surface.
  • This physical absorption of polymers on the cotton surface can now be made more durable since one of the polymer units is covalently linked to the cotton surface by the action of cyclomaltodextrin glucanotransferase. Since these more durable benefits are produced enzymatically, the covalent linking occurs at a much lower temperature, thus, much lower temperatures as compared to conventional wash cycles are feasible in the wash cycle.
