摘要

Composition for oxidation dyeing of human keratinous fibers i.e. hair, comprises an oxidation base, a coupler, an ammonium salt and a polyquaternary ammonium compound, in a medium. Composition for oxidation dyeing of human keratinous fibers i.e. hair, comprises an oxidation base, a coupler, an ammonium salt of formula (R-C(O)-X-N +(R 1)(R 2)-Y 1)(Q -) and a polyquaternary ammonium compound of formula (-N +(R 4)(R 5)-(CH 2) n-N +(R 6)(R 7)-(CH 2) p-)(Q 1 -) 2, in a medium. R : CH 3CH 2-CH(R 3)-CH 2-(CH 2) m-; R 3alkyl, preferably methyl; m : 0-30, preferably 16; R 1, R 2alkyl, alkenyl, alkoxy, alkenyloxy or aryl (the alkyl or alkenyl groups are interrupted by O, S or N(Ralpha )); Ralpha : H or alkyl; X : aminoalkylene of formula -N(R 4)-(CH 2) p-; R 4H or alkyl; p : 1-6; Y 1alkyl or alkoxy (both optionally interrupted by O, S or N(Ralpha )); Q -, Q 1 -counter ion associated with the quaternary ammonium ion, preferably Q 1 - is halide; R 4-R 71-4C (hydroxy)alkyl, preferably methyl or ethyl; and n, p : 2-20. Independent claims are included for: (1) coloring human keratinous fibers by applying the composition in the presence of at least an oxidizing agent, which is mixed just at the moment of employment with the composition; and (2) a device comprising a first compartment comprising the composition and second compartment containing an oxidizing agent.
