Definitions

  • composition (A) is a low-water preparation which contains at least one organic Ci-C6-alkoxysilane
  • composition (B) contains at least one first and at least one second surfactant in addition to water, these two surfactants structurally different from one another are.
  • a second subject 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, 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 colors can be produced which are particularly resistant to shampooing.
  • the organic silicon compounds used in EP 2168633 B1 are reactive compounds from the alkoxy-silane class. These alkoxy-silanes hydrolyze in the presence of water at high speed and - depending on the particular amounts of alkoxy-silane and water used - 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. This means that extremely good dyeing results can be achieved after a very short application period of just a few minutes will. In addition to these advantages, the high reactivity of the alkoxy silanes also has some disadvantages.
  • the organic alkoxy-silanes cannot be made up together with larger amounts of water, since a large excess of water initiates immediate hydrolysis and subsequent polymerization.
  • the polymerization which takes place when the alkoxy-silanes are stored in an aqueous medium is expressed in a thickening or gelling of the aqueous preparation. This makes the preparations so highly viscous, gel-like or gelatinous that they can no longer be applied evenly to the keratin material.
  • the storage of the alkoxy-silanes in the presence of large amounts of water is associated with a loss of their reactivity, so that the formation of a resistant coating on the keratin material is no longer possible.
  • the alkoxy silanes can react not only with water, but also with other cosmetic ingredients.
  • the preparations with alkoxy-silanes therefore preferably contain no further ingredients or only the selected ingredients which have been found to be chemically inert to the alkoxy-silanes.
  • the concentration of the alkoxy silanes in the preparation is accordingly preferably chosen to be relatively high.
  • the low-water preparations, which contain the alkoxy-silanes in relatively high concentrations, can also be referred to as “silane blends”.
  • the user now has to convert this relatively highly concentrated silane blend into a ready-to-use mixture.
  • this ready-to-use mixture on the one hand, the concentration of the organic alkoxy-silanes is reduced and, on the other hand, the application mixture also contains a higher proportion of water (or an alternative ingredient), which triggers the polymerization leading to the coating.
  • Too rapid a polymerization therefore makes the whole head treatment impossible.
  • the too rapid polymerization manifests itself in an extreme uneven color result, so that the hair that was last treated is only poorly colored.
  • the object of the present application was to find a method for treating keratinic material by means of which the rate of polymerization of the organic alkoxysilanes could be adapted to the conditions of use, in particular to the conditions prevailing when used on the human head.
  • a process was sought by which the organic alkoxysilanes remained reactive for so long that a whole-head treatment is made possible without unduly extending the application period.
  • the first composition (A) is the low-water silane blend described above.
  • the second composition (B) contains water and also contains at least two structurally different surfactants.
  • the two compositions (A) and (B) come into contact with one another, this contact being possible either through prior mixing of (A) and (B) or through successive application of (A) and (B) to the keratin 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
  • a first composition (A) which - based on the total weight of the composition (A) - contains
  • 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
  • a first composition (A) which - based on the total weight of the composition (A) - contains
  • (B3) at least one second surfactant which is structurally different from the first surfactant (B2).
  • the surfactants (B2) and (B3) contained in the water-containing composition (B) reduce the rate of polymerization of the organic Ci-C6-alkoxy-silanes (A2) on contact with the composition (A).
  • the reactivity of the organic Ci-C6-alkoxy-silanes (A2) could be optimally adapted to the application conditions prevailing in a whole-head hair coloring process.
  • Even more complicated or more time-consuming coloring techniques, such as the coloring of highlights specially arranged on the head could be implemented using the method according to the invention.
  • 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.
  • Keratinic material is preferably understood to mean human hair, human skin and human nails, in particular fingernails and toenails. Keratinic material is very particularly preferably understood to mean human hair.
  • Agents for treating keratinous material are understood to mean, for example, means for coloring the keratin material, means for reshaping or shaping keratinic material, in particular keratinic fibers, or also means for conditioning or maintaining the keratinic material.
  • the agents produced by the process according to the invention are particularly suitable for coloring keratinic material, in particular for coloring keratinic fibers, which are particularly preferably human hair.
  • the term “means for coloring” is used in the context of this invention for a coloring of the keratin material, especially the hair, caused by the use of coloring compounds, such as thermochromic and photochromic dyes, pigments, mica, substantive dyes and / or oxidation dyes.
  • the aforementioned coloring compounds are deposited in a particularly homogeneous and smooth film on the surface of the keratin material or diffuse into the keratin fiber.
  • the film is formed in situ by oligomerization or polymerization of the organic alkoxy silane (s), and by the interaction of the coloring compound and the organic silicon compound and, optionally, further constituents, such as a film-forming polymer.
  • the method according to the invention is characterized by the use of a first composition (A) on the keratinic material.
  • the composition (A) is characterized in that it is low in water, preferably essentially free of water.
