Definitions

  • This invention generally relates to enzymatic removal of skin-derived body soils from textile, in particular removal of "yellowing” from white textiles.
  • a primary source of so-called yellowing of fabric items such as bed linen, pillow cases, cuffs and collars of shirt is due to accumulation and aging of body soil components.
  • transfer to the textile matrix of sebum and skin residues are of key importance, see J. Surf. Det. (1998), 3: 407-418; J. Surf. Det. (2001 ), 4: 35-41 ; and references therein.
  • Accumulation of oxidation labile compounds may upon aging render yellowish, oxidized and cross-linked structures that are very hard to remove.
  • the present invention provides enzymatic methods for degrading body soil structures on textiles, and thus reducing yellowing and restoring whiteness.
  • the present invention provides a method for removing or releasing the constituents of a skin-derived body soil deposition from textile, comprising contacting the body soil deposition with an oxidoreductase enzyme from EC 1.10.3, EC 1.1 1.1 , EC 1.1 1.2, or EC 1 .13.1 1 .
  • the skin-derived body soil is sebum, preferably aged or oxidized sebum, comprising squalene cross linked through oxygen-bridging to sebum lipids, or proteins/peptides/carbohydrates derived from skin or textile.
  • the textile is a white garment in direct skin contact, such as a cuff, collar, under garment, or a pillow case; preferably the textile is made of cotton.
  • the oxidoreductase is a laccase, lipoxygenase, peroxidase and/or peroxygenase.
  • the inventors of the present invention have surprisingly found that a wash method including enzymes belonging to the family of oxidoreductases significantly restores loss of whiteness due to yellowing of laundry items, in particular regions of laundry items like collars, cuffs and pillow cases.
  • the invention furthermore enables machine wash under mild conditions (moderate pH and temperature), while delivering new benefits like restoring whiteness, reducing risk of undesired abrasion and discoloration (fabric care), as well as added convenience to the consumer. Examples show that machine wash of aged (oxidized) real items of pillow cases that have lost whiteness due to yellowing are not significantly cleaned with respect to restoring whiteness in machine wash under mild conditions by conventional wash methods.
  • a wash method with specific oxidoreductases in machine wash under mild conditions provides surprising benefits with respect to restoring whiteness due to yellowing of fabric items with aged unsaturated sebum lipids.
  • the benefits of the invention include improvement of whiteness, as measured by remission at 460 nanometer, of up to more than 8 units.
  • the invention provides benefits for detergency, fabric care and home care in general where items in contact with skin and body soil lead to accumulation, oxidation, cross- linking and/or entrapment of undesired components to a surface structure.
  • the enzyme(s) used in the present invention are oxidoreductase enzymes from EC 1 .10.3, EC 1.1 1.1 , EC 1.1 1.2, or EC 1.13.1 1 ; based on the recommendations of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (IUBMB), which describes each type of characterized enzyme for which an EC (Enzyme Commission) number has been provided.
