Definitions

  • the present application is in the field of cosmetics and relates to a product for the treatment of keratinous material, in particular human hair, which allows the convenient use of a mixture of compositions (A) and (B).
  • the composition (A) is a low-water preparation which contains at least one organic C 1 -C 6 alkoxysilane, and the composition (B) contains a proportion of water and optionally at least one pigment and/or a polymer.
  • Both compositions (A) and (B) are packaged in two reservoirs (VA) and (VB) of the product.
  • the storage containers (VA) and (VB) are part of a dispenser system and are connected to a mixing device (M).
  • the mixing device (M) enables a mixture of the compositions (A) and (B) to be taken directly from the dispensing system.
  • a second subject of the present application relates to a method for dyeing human hair, in which a product of the first subject of the invention is used and in which the mixture of compositions (A) and (B) is applied to the hair.
  • 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 insoluble, coloring ones substances understood. 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 a combination of pigment, organic silicon compound, hydrophobic polymer and a solvent, colorations can be produced on hair which are particularly resistant to shampooing.
  • the organic silicon compounds used in EP 2168633 B1 are reactive compounds from the class of alkoxysilanes. These alkoxysilanes hydrolyze at high speed in the presence of water and form hydrolysis products and/or condensation products--depending on the amounts of alkoxysilane and water used in each case. 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 a coating is formed on the keratin material, which completely envelops the keratin material and in this way greatly influences the properties of the keratin material.
  • Possible areas of application are, for example, permanent styling or permanent changes in the shape of keratin fibers.
  • the keratin fibers are brought into the desired shape mechanically and then fixed in this shape by forming the coating described above.
  • Another particularly well suited application is the coloring of keratin material; in the context of this application, 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 coloring principle based on alkoxy silanes is that the high reactivity of this class of compounds enables very fast coating. Extremely good coloring results can be achieved after a very short period of use of just a few minutes. In addition to these advantages, the high reactivity of alkoxysilanes also has some disadvantages.
  • the organic alkoxy silanes cannot be formulated together with large amounts of water, since a large excess of water initiates immediate hydrolysis and subsequent polymerization.
  • the polymerization that takes place when the alkoxysilanes are stored in an aqueous medium is reflected in thickening or gelling of the aqueous preparation.
  • the preparations become so highly viscous, gel-like or gelatinous that they can no longer be applied evenly to the keratin material.
  • storage of the alkoxysilanes in the presence of large amounts of water is associated with a loss of their reactivity, so that it is no longer possible to form a resistant coating on the keratin material.
  • the alkoxy silanes can react not only with water but also with other cosmetic ingredients.
  • the preparations with alkoxysilanes therefore preferably contain no other ingredients or only the selected ingredients which have been found to be chemically inert towards the alkoxysilanes. Accordingly, the concentration of the alkoxysilanes in the preparation is preferably selected 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 the concentration of the organic alkoxysilanes is lower, and the application mixture also contains a higher proportion of water (or an alternative ingredient), which triggers the polymerisation that leads to the coating.
  • the preparation of the ready-to-use agent is therefore carried out by mixing the low-water silane blend with a second, preferably water-containing, composition.
  • the ready-to-use agent obtained in this way must have rheological properties that are optimally adapted to the application. If the agent is to be used on the hair on the head, for example, its viscosity must be high enough so that the hair is completely wetted with the agent for the entire duration of the application and this is not removed from the head dripping down his head. For this reason, the ready-to-use agent usually contains a thickener such as a thickening polymer. To avoid incompatibilities, the thickener is preferably not incorporated into the silane blend, but is located in the second, water-containing composition.
  • the low-water silane blend is a liquid with an extremely low viscosity, which now has to be mixed with a comparatively heavily thickened, preferably water-based composition to produce the ready-to-use agent.
  • the ready-to-use agent must be completely homogeneous, so that the user needs a certain amount of time to prepare the ready-to-use agent when mixing manually.
  • the silane blend is a highly reactive system, producing the ready-to-use agent is a major challenge for the user. If the user does not exercise enough care when mixing the blend and any thickened carrier, the application mixture will not be completely homogeneous, which can lead to an uneven result on the keratin material. In particular when used in a coloring process on the hair, the color result can be correspondingly uneven, piebald and unattractive.
  • the oligomerization or polymerization of the silanes may have progressed too far or even be complete before the user has applied the agent to all sections of hair. In the dyeing process, this also manifests itself in an extremely uneven or insufficient color result, and in particular the sections of hair that were last treated are then dyed poorly and with too little intensity.
  • a product with a dispenser system that includes two separate storage containers that are in contact with a mixing device or are connected to it.
  • the two reservoirs contain the low-water silane blend and the optionally water-containing, thickened carrier formulation, and the mixing device ensures that these two preparations are mixed reproducible and reliable way without the user having to perform separate or manual mixing.
  • a first subject matter of the present application is therefore a product for the treatment, in particular for coloring, of keratin material, comprising a dispenser system with

  • Agents for treating keratin material include, for example, agents for coloring keratin material, agents for reshaping or shaping keratin material, understood in particular keratin fibers, or agents for conditioning or care of the keratin material.
  • the ready-to-use 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.
  • coloring agent is used in the context of this invention for coloring the keratin material, in particular the hair, caused by the use of pigments.
