Definitions

  • the present invention relates to a dye-transfer inhibitory preparation comprising a peroxidase and an accelerator, and to a detergent composition comprising such a dye-transfer inhibitory preparation.
  • the invention further relates to a method of laundry washing (i.e. washing of textile or fabric articles, such as articles of clothing and the like) so as to inhibit fabric-to-fabric transfer of dye (or other colourant) during washing.
  • dye-transfer inhibition i.e. inhibition of fabric-to-fabric transfer of dye during washing
  • WO 91/05839 discloses that dye-transfer inhibition can be achieved with a preparation comprising a peroxidase and "another oxidisable substrate" (see page 10, lines 7-19, of WO 91/05839), the first oxidisable substrate being the dye in question.
  • another oxidisable substrate as referred to above will be referred to hereinafter in the present specification with claims as an "accelerator”.
  • Dye-transfer inhibition is a very sensitive process, and a very desirable goal in this connection is bleaching of the washing liquor (i.e. removal of coloration by degradation of dye dissolved in the washing liquor) by enzymatic means without discoloration of dye which remains fixed to the laundry articles undergoing washing.
  • a first aspect of the present invention provides a dye-transfer inhibitory preparation comprising granules containing co-granulated peroxidase and accelerator. It is generally preferable (e.g. from the point of view of robustness during handling, and prevention of dust formation) that the granules are coated with an appropriate coating; suitable coating agents for this purpose include substances such as polyethylene glycols (e.g. PEG 4000).
  • peroxidase system i.e. a peroxidase together with hydrogen peroxide or a source thereof
  • compositions such as detergent compositions for laundry washing

  • a dye-transfer inhibitory preparation of the invention is in the form of a slow-release coated co-granulate comprising a peroxidase and an accelerator (vide supra). It appears that the use of such a dye-inhibitory preparation of the invention in washing/cleaning compositions of the types mentioned above, e.g. detergent compositions for laundry washing, can result in significant reduction or elimination of the above-described, unwanted, oxidative side-effects of peroxidase systems, notably with respect to inactivation of other enzymes present before they have exerted their intended effect.
  • the peroxidase/-accelerator co-granulate preparation of the invention is a slow-release coated co-granulate, that the preparation is one in which one or more peroxidases is/are the only enzymatic component(s).
  • a preparation of the invention as an supplement to, e.g., a laundry detergent composition results (vide infra) in very satisfactory inhibition of fabric-to- fabric transfer of dye (or other colouring material, e.g. from coloured stains) during a laundry washing process.
  • Dye-inhibitory preparations of the invention are also very well suited for use in the rinsing or washing of fabrics or textiles after they have been dyed, and preparations of the invention may be employed, e.g., in conjunction with, or as a component of, compositions for this purpose.
  • the scope of the invention encompasses such compositions.
