Abstract:
A ready-to-use composition for the oxidation dyeing of keratin fibers comprising:at least one solvent chosen from water and organic solvents, at least one oxidation base, at least one first coupler chosen from the meta-phenylenediamines of formula (I) below, and acid-addition salts thereof: â€ƒin which: R1 is chosen from a hydrogen atom, C1-C4 alkyl radicals, C1-C4 monohydroxyalkyl radicals and C2-C4 polyhydroxyalkyl radicals; R2 and R3, which may be identical or different, are chosen from a hydrogen atom, C1-C4 alkyl radicals, C1-C4 monohydroxyalkoxy radicals and C2-C4 polyhydroxyalkoxy radicals; R4 is chosen from a hydrogen atom, C1-C4 alkoxy radicals, C1-C4 aminoalkoxy radicals, C1-C4 monohydroxyalkoxy radicals, C2-C4 polyhydroxyalkoxy radicals and 2,4-diaminophenoxyalkoxy radicals; and wherein at least one of said radicals R1 to R4 is a radical other than a hydrogen atom, at least one second coupler chosen from meta-aminophenols, meta-diphenols and acid-addition salts thereof, at least one enzyme chosen from 2-electron oxidoreductases, at least one donor for said enzyme; and wherein said composition does not contain the combination of 2-amino-4-N-(&bgr;-hydroxyethyl)amino-1-methoxybenzene, 4-amino-3-methylphenol and 5-amino-2-methylphenol.
