Abstract:
A composition for dyeing keratinous fibers comprising:(a) at least one enzyme of the laccase type; (b) at least one cationic substantive polymer, at least one amphoteric substantive polymer or at least one mixture thereof, wherein said substantive polymers are chosen from: (i) Polyquaternium-24; (ii) copolymers derived from monomers of dimethyldiallylammonium halide; (iii) homopolymers and copolymers derived from monomers of methacryloyloxyethyltrimethylammonium halide; (iv) poly(quaternary ammonium) polymers chosen from formulae (I), (II) and (III): polymers comprising units of formula (I): polymers comprising units of formula (II): polymers comprising units of formula (III): in which p is an integer ranging from 1 to 6, D is chosen from a bond, and â€”(CH2)râ€”COâ€” groups, in which r is chosen from 4 and 7; (v) polymers derived from monomers of vinylpyrrolidone comprising cationic units; and (vi) cationic polysiloxanes chosen from products derived from amodimethicones of formula (IV): (c) at least one oxidation dye and the acid addition salts thereof; with the proviso that the composition does not comprise hydrogen peroxide.
