Patent

CA 2303125

The invention relates to enzymatic foam compositions adapted for dyeing of keratinous fibres, e.g. hair, fur, hide or wool, comprising: 1) at least one oxidation enzyme, typically an oxidoreductase selected from laccases and related enzymes, oxidases and peroxidases; 2) at least one foaming agent, e.g. selected from soaps and anionic, non-ionic, amphoteric and zwitterionic surfactants; 3) at least one dye precursor, e.g. selected from diamines, aminophenols and phenols; and optionally 4) at least one modifier, e.g. selected from m-aromatic diamines, m-aminophenols and polyphenols. The invention also relates to a method for dyeing keratinous fibres using the foam compositions and use of the foam compositions for dyeing keratinous fibres. The foamed compositions of the invention provide an improved uniformity of the dyeing effect.

Cette invention porte sur des compositions de mousse enzymatiques conçues pour teinter des fibres de kératine telles que les cheveux, la fourrure, le cuir ou la laine. ces compositions comprennent: 1) au moins une enzyme d'oxydation, généralement une oxydoréductase sélectionnée à partir de laccases et d'enzymes connexes, d'oxydases et de peroxydases; 2) au moins un agent moussant sélectionné à partir de savons et des tensioactifs anioniques, non ioniques, amphotères et zwittérioniques; 3) au moins un précurseur de colorant sélectionné à partir de diamines, de m-aminophénols et de polyphénols. Cette invention porte également sur un procédé de coloration de fibres de kératine utilisant les compositions de mousse, ainsi que sur l'utilisation de ces compositions de mousse dans la coloration des fibres de kératine. Ces compositions de mousse permettent d'obtenir une meilleure uniformité de l'effet colorant.
