Claim:
Agent for treating keratinic fibers comprising in a cosmetic carrier: (i) at least one oxidizing agent, (ii) at least one acylpyridinium derivative of Formula (I) in which R1 is a C 1 -C 6 alkyl group, a C 2 -C 6 alkenyl group, a C 2 -C 6 hydroxyalkyl group, a C 1 -C 6 alkoxy C 2 -C 6 alkyl group, a carboxy C 2 -C 6 alkyl group, an aryl C 1 -C 6 alkyl group, a heteroaryl C 1 -C 6 alkyl group, an aryl group or a heteroaryl group, R2, R3 and R4, each independently of one another, is hydrogen, a C 1 -C 6 alkyl group, a halogen atom or a C 1 -C 6 acyl group, with the proviso that at least one of R2, R3 and R4 is a C 1 -C 6 acyl group, and X − is a physiologically acceptable anion, and (iii) at least one hydroxyl group-containing ammonium compound of Formula (II), wherein Y is either a carboxylate group (CO 2 − ), or a carboxylic acid group (CO 2 H), an alkali metal carboxylate group (CO 2 M) or a carboxylic acid C 1 -C 6 alkyl ester group, wherein the compound of Formula (II) contains a physiologically acceptable anion to compensate for the positive charge.
