Water-in-oil emulsion for treating keratinic materials, especially for oxidation dyeing, perming or bleaching hair, comprises an oxidizing agent, a fatty alcohol, a surfactant and an amphiphilic polymer

摘要

Water-in-oil emulsion for treating keratinic materials comprises an oxidizing agent, a fatty alcohol with 8-30 carbon atoms, a nonionic and/or anionic surfactant, and an amphiphilic polymer comprising 2-acrylamido-2-methylpropane sulfonic acid units, optionally in alkali(ne earth) metal or ammonium salt form, and hydrophobic units with 6-50 carbon atoms. Independent claims are also included for: (1) oxidation dyeing of human keratinic fibers using an oxidation dye composition and an emulsion as above; (2) imparting permanent deformation to human keratinic fibers by putting the fibers under tension before, during or after application of a reducing composition, optionally rinsing the fibers, applying an emulsion as above, and optionally rinsing the fibers; (3) bleaching human keratinic fibers by applying an emulsion as above and rinsing the fibers.
