Definitions

  • the invention relates to processes for the color change of keratin-containing fibers, wherein the ready-to-use agent is prepared by shaking two separately formulated preparations into a foam before use.
  • the invention relates to a two-part colorant and corresponding multi-component kit for dyeing keratin-containing fibers.
  • oxidation dyes which are formed by oxidative coupling of one or more developer components with one another or with one or more coupler components
  • Coupler and developer components are also referred to as oxidation dye precursors.
  • the colors obtained with oxidation colors are usually referred to as permanent or semi-permanent colorations.
  • oxidative whitening processes are mostly used in which natural or synthetic dyes in the hair fiber are oxidatively destroyed and thereby decolorized.
  • oxidative dyeing and whitening agents for accelerating the reaction during the oxidative use have an alkaline pH, which is adjusted with alkalizing agents, such as alkanolamines, ammonia or inorganic bases.
  • alkalizing agents such as alkanolamines, ammonia or inorganic bases.
  • ammonia allows good dyeing results, but also reveals disadvantages for the user due to its odor and irritation potential for skin and mucous membranes. Therefore, increased efforts are being made to develop powerful oxidative dyeing and whitening agents that dispense with the use of ammonia.
  • oxidizing agent these agents usually contain hydrogen peroxide. Since hydrogen peroxide is only insufficiently stable on storage in the alkaline pH range, oxidative coloring and / or brightening agents usually consist of two components which are mixed together immediately before use. This raises the problem of a homogeneous mixing of the two components on the one hand, which could be solved by correspondingly easily miscible components, in particular low-viscosity liquids. On the other hand, however, the application mixture must be sufficiently viscous enough to be conveniently applied to the hair can and does not drip during the exposure time.
  • foams are ideal when there is a firm, stable foam that leaves a supple feel and breaks slowly on the hair. Frequently, however, it can be observed that the foams applied are less stable and quickly collapse again, so that a thin, dripping solution remains. On the other hand, it is also essential that the foam still wets the hair well, so that a good application of paint can take place.
  • this application form is intended to enable a drip-free application and, on the other hand, to be inferior in performance to the commercial cream or gel applications, in particular with regard to whitening and staining properties and fastness properties.

Cocoamidopropylbetaine is also described as a suitable surfactant with a high surfactant content in tinted foams based on substantive dyes in WO 2006/066642 (A1).

  • the foamy agents can be very easily and evenly spread by hand on the hair and thus allow easy handling.
  • the compositions of the invention allow more intense color results, especially in terms of intensity, gray coverage and gloss, and achieve significantly more durable color results than previously known foam preparations.
  • the foam application allows an excellent care effect in the application, especially because a homogeneous distribution is ensured so that undesirable high local concentrations of the dyeing or bleaching are avoided. Furthermore, the funds are low in odor.
