  • lipase such as M1 Lipase (Ibis) and Lipolase (Novo).
  • Peroxidase enzymes are used in combination with oxygen sources, e.g. percarbonate, perborate, persulfate, hydrogen peroxide, etc. They are used for "solution bleaching", i.e. to prevent transfer of dyes of pigments removed from substrates during wash operations to other substrates in the wash solution.
  • Peroxidase enzymes are known in the art, and include, for example, horseradish peroxidase, ligninase, and haloperoxidase such as chloro- and bromo-peroxidase.
  • Peroxidase-containing detergent compositions are disclosed, for example, in PCT Internation Application WO 89/099813, published October 19, 1989, by O. Kirk, assigned to Novo Industries A/S, and in European Patent application EP No. 0 540 784, filed on November 6, 1991.
  • the enzymes are preferably coated or prilled with additives inert toward the enzymes to minimize dust formation and improve storage stability. Techniques for accomplishing this are well-known in the art.
  • an enzyme stabilization system is preferably utilized. Enzyme stabilization techniques for aqueous detergent compositions are well known in the art.
  • one technique for enzyme stabilization in aqueous solutions involves the use of free calcium ions from sources such as calcium acetate, calcium formate and calcium propionate. Calcium ions can be used in combination with short chain carboxylic acid salts, preferably formates. See, for example, U.S. patent 4,318,818, Letton, et al, issued March 9, 1982.
  • Non-boric acid and borate stabilizers are preferred. Enzyme stabilization systems are also described, for example, in U.S. Patents 4,261,868, 3,600,319 and 3,519,570.
  • Other suitable detergent ingredients that can be added are enzyme oxidation scavengers which are described in Copending European Patent aplication N 0 553 607 filed on January 31, 1992. Examples of such enzyme oxidation scavengers are ethoxylated tetraethylene polyamines.
  • Especially preferred detergent ingredients are combinations with technologies which also provide a type of color care benefit. Examples of these technologies are cellulase and/or peroxidases and/or metallo catalysts for color maintance rejuvenation.
  • the detergent compositions according to the invention can be in liquid, paste or granular forms.
  • Granular compositions according to the present invention can also be in "compact form", i.e. they may have a relatively higher density than conventional granular detergents, i.e. from 550 to 950 g/l; in such case, the granular detergent compositions according to the present invention will contain a lower amount of "inorganic filler salt", compared to conventional granular detergents; typical filler salts are alkaline earth metal salts of sulphates and chlorides, typically sodium sulphate; "compact" detergents typically comprise not more than 10% filler salt.
  • the liquid compositions according to the present invention can also be in "compact form", in such case, the liquid detergent compositions according to the present invention will contain a lower amount of water,compared to conventional liquid detergents.
  • the present invention also relates to a process for inhibiting dye transfer from one fabric to another of solubilized and suspended dyes encountered during fabric laundering operations involving colored fabrics.
  • the process comprises contacting fabrics with a laundering solution as hereinbefore described.
  • the process of the invention is conveniently carried out in the course of the washing process.
  • the washing process is preferably carried out at 5 °C to 75 °C, especially 20 to 60°C, but the polymers are effective at up to 95 °C.
  • the pH of the treatment solution is preferably from 7 to 11, especially from 7.5 to 10.5.
  • the process and compositions of the invention can also be used as additive during laundry operations.
  • compositions of the present invention are meant to exemplify compositions of the present invention , but are not necessarily meant to limit or otherwise define the scope of the invention, said scope being determined according to claims which follow.
  • a liquid detergent composition according to the present invention is prepared, having the following compositions : % by weight of the total detergent composition Linear alkylbenzene sulfonate 10 Alkyl sulphate 4 Fatty alcohol (C 12 -C 15 ) ethoxylate 12 Fatty acid 10 Oleic acid 4 Citric acid 1 NaOH 3.4 Propanediol 1.5 Ethanol 10
  • the extent of dye transfer is assessed by a Hunter Colour measurement.
  • the Hunter Colour system evaluates the colour of a fabric sample in terms of the ⁇ c value which represents the change in the Hunter a, b values which are determined by reflecting spectrometrie.
  • the extent of dye transfer from different colored fabrics was studied using a launder-o-meter test that simulates a 30 min wash cycle.
  • the launder-o-meter beaker contains 200 ml of a detergent solution, a 10cmx10cm piece of the colored fabric and a multifiber swatch which is used as a pick-up tracer for the bleeding dye.
