Definitions

  • the present invention relates to bleaching agents which serve as agents for lightening keratin fibers, in particular human hair. Furthermore, the present invention relates to a multi-component packaging unit (kit-of-parts) for gentle bleaching of human hair and a method for bleaching human hair.
  • the bleaching agent is an anhydrous, powdered cosmetic composition in a package, the cosmetic composition containing at least one persalt. Lightening your own hair color has always been the wish of many consumers, since a blonde hair color is considered attractive and desirable in terms of fashion.
  • Various bleaching agents with different bleaching performance are available on the market for this purpose.
  • the oxidizing agents contained in these products are able to lighten the hair fiber through the oxidative destruction of the hair's own dye melanin.
  • the use of hydrogen peroxide - if appropriate using ammonia or other alkalizing agents - as the oxidizing agent alone is sufficient.
  • the agents contain higher use concentrations of hydrogen peroxide and percarbonates or persalts, in particular persulfates. Dark, dark brown or black hair can be lightened by 4 to 6 shades in one step.
  • the hydrogen peroxide and the percarbonates or persalts are kept separate from one another until use, so as not to prematurely deactivate the percarbonates or persalts.
