Definitions

  • Process for coloring keratinous material comprising the use of an organosilicon compound, a coloring compound, a sealing agent and an alkaline pretreatment agent
  • agent (a) is characterized by its content of at least one organic silicon compound (a1).
  • agent (b) contains at least one sealing reagent (b1).
  • agent (a) or agent (b) or both agents (a) and (b) contain at least one color-providing compound from the group of pigments and/or direct dyes.
  • kits-of-parts for dyeing keratin material, in particular human hair, which is made up separately of at least three agents (a′), (a′′) and (b) and a pretreatment agent (v) includes.
  • the agent (a) used in the method described above can be prepared from the agents (a') and (a").
  • a multi-component packaging unit for coloring keratin material, in particular human hair, which, separately from one another, contains at least four means (a'), (a"), (a"') and (b) and a pretreating agent (v).
  • the agent (a) used in the process described above can be prepared from the agents (a'), (a") and (a"').
  • Oxidation colorants are usually used for permanent, intensive colorations with good fastness properties and good gray coverage. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components, which form the actual dyes with one another under the influence of oxidizing agents such as hydrogen peroxide. Oxidation coloring agents are characterized by very long-lasting coloring results.
  • color pigments are generally understood to mean insoluble, color-imparting substances. These are present in undissolved form in the form of small particles in the coloring formulation and are only deposited from the outside on the hair fibers and/or the surface of the skin. Therefore, they can usually be removed without leaving any residue with a few washes with detergents containing surfactants.
  • Various products of this type are available on the market under the name of hair mascara.
  • EP 2168633 B1 deals with the task of producing long-lasting hair coloring using pigments.
  • the document teaches that when using the combination of a pigment, an organic silicon compound, a film-forming polymer and a solvent, colorations can be produced on hair which are particularly resistant to abrasion and/or shampooing.
  • the object of the present invention was to provide a dyeing system with pigments which has fastness properties comparable to oxidative dyeing.
  • the fastness to washing should be outstanding, but the use of the oxidation dye precursors otherwise usually used for this purpose should be avoided.
  • an even and long-lasting coloring should also be achieved.
  • the above object can be achieved in an excellent manner if keratin materials, in particular human hair, are dyed using a process in which first an alkaline pretreatment agent (v) and then at least two agents (a) and (b) applied to the keratin materials (hair).
  • the first agent (a) contains at least one organic silicon compound from the group of silanes having one, two or three silicon atoms.
  • the second means (b) contains at least one sealing reagent.
  • agent (a) or agent (b) or both agents (a) and (b) contain at least one color-providing compound from the group of pigments and/or direct dyes.
  • keratinic material When using the three agents (v), (a) and (b) in a dyeing process, keratinic material could be dyed with particularly high color intensity and high fastness properties.
  • a surprisingly uniform and long-lasting application of the at least one coloring compound could be achieved by pretreating the keratinic material with an alkaline pretreatment agent.
  • a first object of the present invention is a method for coloring keratin material, in particular human hair, comprising the following steps:
  • agent (v) to the keratin material, the agent (v) containing:
  • (v1) at least one polyethylene glycol with an average molecular weight of 200 to 8,000 g/mol

  • (b1) at least one sealing agent, where at least one of the agents (a) and (b) also contains at least one color-providing compound from the group of pigments and/or direct dyes.
  • the alkaline pretreatment removes the fatty acid 18-methyleicosanoic acid covalently bound to the surface of the cuticle of the keratin material through an ester or thioester bond. Cleavage of the ester or thioester bond and removal of the covalently bound 18-methyleicosanoic acid renders the keratinic material hydrophilic and creates additional reactive sites on the surface of the keratinic material. The other reactive points on the surface of the keratin material can in particular be negatively charged.
  • the organosilicon compounds (a1) and/or their condensation and/or hydrolysis products can interact with the negative charges.
