  • the invention provides use of an arginine alkyl ester in combination with one or more enzymes, in the removal of a stain from a stained substrate under ambient conditions.
  • the arginine alkyl ester enhances the enzymatic removal of stains present on fabric and is effective at lower temperatures. This offers improved laundry (i.e. fabric) cleaning of stained fabrics in regions where ambient water washing is prevalent. Improved washing performance at lower temperatures may help inhibit the adoption of hot water washing in these countries, a rising trend as standards of living increase and more people are able to afford washing machines.
