Abstract (en)

[origin: WO9915137A1] 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.
