  • Ready-to-use aqueous composition for bleaching keratin fibers, comprising a combination of a water-soluble solvent and a nonionic and/or anionic amphiphilic polymer comprising at least one fatty chain
    Patent number: 6641618
    Abstract: Ready-to-use aqueous composition for bleaching keratin fibers, in particular, human keratin fibers, containing a combination of at least one alkaline agent, at least one peroxygenated salt, hydrogen peroxide, at least one water-soluble solvent, and at least one amphiphilic polymer chosen from nonionic and anionic amphiphilic polymers and comprising at least one fatty chain, and a process for bleaching the hair using these aqueous compositions.
    Type: Grant
    Filed: January 28, 2000
    Date of Patent: November 4, 2003
    Assignee: L'Oreal S.A.
    Inventors: Frédéric Legrand, Jean Millequant
  • Anhydrous composition for bleaching keratin fibers comprising a combination of a water-soluble thickening polymer and a nonionic amphiphilic polymer comprising at least one fatty chain
    Patent number: 6379401
    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.
