Compositions suitable for treating keratinic fibers, in particular human hair, are disclosed, which compositions comprise: (i) at least one component selected from the group consisting of salt compounds of general formula I, enamine counterparts of salt compounds of general formula I, and mixtures thereof: wherein each Me represents a methyl group, R represents a substituent selected from the group consisting of an allyl group, a hydroxy-(C2-6)-alkyl group, a benzyl group, and substituted benzyl groups, and X− represents a physiologically compatible anion; and (ii) at least one aldehyde selected from the group consisting of 4-hydroxy-3-methoxybenzaldehyde, 3,5-dimethoxy-4-hydroxybenzaldehyde, 4-hydroxy-1-naphthaldehyde, 4-hydroxy-2-methoxybenzaldehyde, 3,4-dihydroxy-5-methoxybenzaldehyde, 3,4,5-tri-hydroxybenzaldehyde, 3,5-dibromo-4-hydroxybenzaldehyde, 4-hydroxy-3-nitrobenzaldehyde, 3-bromo-4-hydroxybenzaldehyde, 4-hydroxy-3-methylbenzaldehyde, 3,5-dimethyl-4-hydroxybenzaldehyde, 5-bromo-4-hydroxy-3-methoxybenzaldehyde, 4-diethylamino-2-hydroxybenzaldehyde, 4-dimethylamino-2-methoxybenzaldehyde, and mixtures thereof.
摘要:
Fiber-coloring components for dye compositions and methods for using the same, wherein the compositions comprise: (i) at least one component A comprising a compound selected from imidazo[1,5-a]pyrimidinium derivatives of general formula I, enamine counterparts of such derivatives, and mixtures thereof: and (ii) at least one component B comprising a reactive carbonyl compound.
摘要:
The invention relates to agents for coloring fibers containing keratin, in particular, human hair, which comprise selected cationic, CH-acidic heterocycles according to formula I in which A, R1, R2 and X− are as defined in the application, in combination with reactive carbonyl compounds, to the use of this combination in agents for coloring fibers containing keratin, for freshening up the color or nuancing fibers containing keratin which have already been colored, and to a method of coloring fibers containing keratin, in particular, human hair.
