  • a second subject of the present invention is a multicomponent packaging unit (kit-of-parts) for coloring keratinous material, which, separately packaged in two packaging units, comprises the cosmetic preparations (A) and (B), the composition (A ) is a composition of the first subject matter of the invention and the composition (B) contains at least one coloring compound.
  • kit-of-parts for coloring keratinous material
  • Oxidation dyes are usually used for permanent, intense dyeings with good fastness properties and good gray coverage. Such colorants usually contain 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 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 rewashed with a few washes with detergents containing surfactants Remove without leaving any residue.
  • Various products of this type are available on the market under the name of hair mascara.
  • oxidative coloring agents have so far been his only option.
  • 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 a combination of pigment, organic silicon compound, hydrophobic polymer and a solvent is used, hair can be colored which is particularly resistant to shampooing.
  • the organic silicon compounds used in EP 2168633 B1 are reactive compounds from the class of alkoxy-silanes. These alkoxy-silanes hydrolyze in the presence of water at high speed and - depending on the amounts of alkoxy-silane and water used in each case - form hydrolysis products and / or condensation products. The influence of the amount of water used in this reaction on the properties of the hydrolysis or condensation product is described, for example, in WO 2013068979 A2.
  • a film or also a coating forms on the keratin material, which completely envelops the keratin material and in this way strongly influences the properties of the keratin material.
  • Possible areas of application are, for example, permanent styling or the permanent change in shape of keratin fibers.
  • the keratin fibers are mechanically brought into the desired shape and then fixed in this shape by forming the above-described coating.
  • Another very particularly suitable application is the coloring of keratin material;
  • the coating or the film is produced in the presence of a coloring compound, for example a pigment. The film colored by the pigment remains on the keratin material or the keratin fibers and results in surprisingly wash-resistant colorations.
  • the great advantage of the alkoxy-silane-based coloring principle is that the high reactivity of this class of compounds enables very fast coating. In this way, extremely good staining results can be achieved after a very short application period of just a few minutes.
  • the high reactivity of the alkoxy silanes also has some Disadvantage. Even minor changes in production and application conditions, such as changes in humidity and / or temperature, can lead to strong fluctuations in product performance. Above all, the work leading to this invention has shown that the alkoxy silanes are extremely sensitive to the conditions that prevail during the production and storage of the keratin treatment agents.
  • the alkoxy silanes can enter into complex hydrolysis and condensation reactions, which lead to mixtures of monomeric, dimeric and oligomeric compounds in equilibrium with one another. If the alkoxysilanes are compounds which contain several hydrolyzable alkoxy groups, each alkoxysilane can also enter into several condensation reactions. Depending on the number of condensations occurring per alkoxysilane molecule, the formation of linear condensates and also the formation of crosslinked, three-dimensional networks is possible.
  • the object of the present application to find a composition for the treatment of keratin material which contains the silane oligomers or silane condensates in an optimal mixture and composition.
  • the alkoxy silanes used to produce the agent should be hydrolyzed and condensed in a targeted manner in such a way that compositions with the optimal application properties could be obtained.
  • the agents produced in this way should have improved dyeing performance, i. E. When they are used in a dyeing process, dyeings with higher color intensity and improved fastness properties, in particular with improved wash fastness and improved rub fastness, should be achieved.
  • a composition is used to treat the keratin material which is a mixture of monomeric silanes (a) of a formula (I), dimeric or linear silane condensates (b) and (c) with structural units of the formulas (II) and (III), crosslinked silane condensates (d) with structural units of the formula (IV) and also siloxanes of the formula (V) and / or (VI).
