Abstract
A water-containing hydrogen peroxide composition having a pH of 2 to 6 for the oxidative dyeing and bleaching of hair. The composition contains an anionic surfactant, hydrogen peroxide, a water-soluble or water-dispersible, thickening polymer or copolymer containing carboxyl or carboxylate groups, and optionally a C.sub.12 -C.sub.18 fatty alcohol ethoxylated with up to 50 moles of ethylene oxide or a hydrogenated castor oil ethoxylated with up to 50 moles of ethylene oxide, and 0.001% to 0.05% by weight of a foam regulator component consisting of polysiloxane containing fine-particle hydrophobicized silica, wherein the content of fine-particle hydrophobicized silica is from 0.5% to 20% by weight, based on the weight of the foam regulator component.
