Abstract

Agent for bleaching keratin fibers comprising in a cosmetic carrier at least one cationic acyl pyridinium derivative of formula (I)where R is a C1-C6-alkyl group, a C2-C6-alkenyl group, a C2-C6-hydroxy alkyl group, a C1-C6-alkoxy-C2-C6-alkyl group, a carboxy-C1-C6-alkyl group, an aryl-C1-C6-alkyl group, a C1-C6-dialkylamino-C2-C6-alkyl group, a heteroaryl-C1-C6-alkyl group, a 3-oxobutyl group, a 2-oxopropyl group, an aryl group, or a heteroaryl group, R′ is a C1-C4-alkyl group, a C2-C6-hydroxy alkyl group, or a C1-C6-alkoxy-C2-C6-alkyl group, X− is a physiologically compatible anion, at least one toxicologically safe co-bleaching activator and/or the physiologically compatible salt thereof, and hydrogen peroxide.
