Definitions

  • a method of coloring keratinous material comprising the use of an organic C 1 -C 6 alkoxysilane and fibers
  • the present application is in the field of cosmetics and relates to a method for treating keratinous material, in particular human hair, which comprises the use of two compositions (A) and (B).
  • the composition (A) is a preparation which contains at least one organic C 1 -C 6 -alkoxysilane, and the composition (B) contains fibers or a fibrous material.
  • a second subject matter of the present invention is a multi-component packaging unit (kit-of-parts) for coloring keratinous material, which, separately packaged in two packaging units, comprises the two compositions (A) and (B) described above
  • Oxidation dyes are usually used for permanent, intensive 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 dyeing results.
  • color pigments are generally understood to mean insoluble, coloring substances. These are undissolved in the form of small particles in the dye formulation and are only deposited on the outside of the hair fibers and / or the surface of the skin. 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 a detrimental 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 coating is formed 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, good staining results can be achieved after a short application period of just a few minutes.
  • the coating is created on the surface of the keratin material and does not change the structure inside the keratin, so this coloring technology is a very gentle method of changing the color of the keratin material.
  • Coloring processes that use the formation of colored films or coatings, however, are still in need of optimization. In particular, the color intensities and the fastness properties of the dyeings achieved with this dyeing system can still be further improved. The manageability, the consistency and the applicability of the formulations also still require optimization.
  • the first composition (A) contains at least one organic C 1 -C 6 -alkoxy-silane (A1) and / or its condensation product
  • the second composition (B) is characterized by its fiber content or its content of a fibrous one Material.
  • a first object of the present invention is a method for treating keratinic material, in particular human hair, in which the keratinic material is used
  • composition (A) was applied to the keratin material in the course of a dyeing process, an improvement in the color intensity, the wash fastness and the rub fastness could be found, especially if the compositions (A) and (B) were mixed with one another before application and in their mixture were added to the keratin material. Even when the composition (B) was applied to the keratin material in the form of an aftertreatment agent after application of the composition (A), very good results could be obtained.
  • Keratinic material is understood to mean hair, skin, and nails (such as fingernails and / or toenails, for example). Furthermore, wool, furs and feathers also fall under the definition of keratinic material.
