Abstract
The present invention relates to anhydrous compositions for bleaching keratin fibers, in particular human keratin fibers, containing at least one alkaline agent, at least one peroxygenated salt, at least one water-soluble thickening polymer, and at least one nonionic amphiphilic polymer including at least one fatty chain, to the use of these compositions to prepare ready-to-use bleaching compositions by mixing with an aqueous hydrogen peroxide composition, and to a process for bleaching the hair using these anhydrous compositions.
