Definitions

  • a method of coloring keratinous material comprising the use of an organosilicon compound, a coloring compound, a modified one
  • the present application relates to a method for treating keratinous material, in particular human hair, which comprises the use of two agents (a) and (b).
  • the agent (a) is characterized by its content of at least one organic silicon compound (a1) and at least one sulfated and / or sulfonated fatty acid ester (a2).
  • the agent (b) contains at least one sealing reagent (b1) and at least one first coloring compound (b2).
  • kits-of-parts for coloring keratinous material, in particular human hair, which comprises at least four means (a), (a ”) and (b) separately made up.
  • the means (a) used in the method described above can be prepared from means (a ‘) and (a“).
  • Oxidation dye precursors so-called developer components and coupler components, which, under the influence of oxidizing agents such as hydrogen peroxide, form the actual dyes with one another.
  • Oxidation dyes are characterized by very long-lasting coloring results.
  • Color pigments known. Color pigments are generally understood to mean insoluble, coloring substances. These are present undissolved in the form of small particles in the coloring formulation and are only deposited on the outside of the hair fibers and / or the skin surface. Therefore, they can usually be removed without residue by a few washes with detergents containing surfactants. Various products of this type are available on the market under the name of hair mascara. If the user wants particularly long-lasting coloring, the use of oxidative coloring agents has so far been his only option. However, despite multiple attempts at optimization, an unpleasant smell of ammonia or amine cannot be completely avoided with oxidative hair coloring. The hair damage still associated with the use of oxidative coloring agents also has an adverse effect on the user's hair.
  • EP 2168633 B1 deals with the problem of producing long-lasting hair colorations using pigments.
  • the document teaches that when the combination of a pigment, an organic silicon compound, a film-forming polymer and a solvent is used, the hair can be colored which is particularly resistant to shampooing.
  • EP 2168633 B1 deals with the problem of producing long-lasting hair colorations using pigments.
  • the document teaches that when a combination of pigment, organic silicon compound, hydrophobic polymer and a solvent is used, the hair can be colored which should be particularly resistant to shampooing.
  • the object of the present invention was to provide a dyeing system which has fastness properties that are comparable to oxidative dyeing. especially the

  • This special type of packaging i.e. the joint use of silane (a1) and sulfated and / or sulfonated fatty acid ester (a2) and the separate application of the sealing reagent (b1) and the first coloring compound (b2) - the film system produced in this way showed an improved resistance to external influences .
  • the adhesion of the coloring compound (b2) could be increased significantly. This made it possible to obtain extremely rub-fast and wash-fast dyeings with good resistance to shampooing.
  • the first coloring compounds (b2) were fixed particularly permanently on the keratinic material when a film-forming polymer was used as the sealing reagent (b1).
