Bleaching agents for keratin-containing fibers, in particular, human hair, comprising (a) at least one peroxo compound and/or at least one alkalinizing agent chosen from ammonium, alkali metal and alkaline earth metal carbonates, hydrogencarbonates and carbamides (b) hydrogen peroxide, and (c) SiO 2 compounds, where the last-mentioned compounds may be optionally hydrated. The agents have an effect of lightening the color of keratin-containing fibers, in particular, human hair. Preferably the bleaching agents are in a pH range of from 4.5 to 9.0. The bleaching agents have a particularly gentle effect on the keratin-containing fibers and the skin. |
