Definitions

  • the present invention relates to a special application device for applying an application liquid to keratinic fibers, in particular a liquid dyeing preparation, based on nature-analogous dyes.
  • Human hair as an example of a keratin fiber is treated today in many ways with hair cosmetic preparations. These include, for example, the cleansing of hair with shampoos, the care and regeneration with rinses and cures and the bleaching, dyeing and shaping of the hair with dyes, tinting agents, waving agents and styling preparations. In this case, means for changing or nuancing the color of the head hair play a prominent role.
  • dyeing or tinting agents which contain as coloring component so-called substantive dyes. These are dye molecules that attach directly to the hair and do not require an oxidative process to form the paint. These dyes include, for example, the henna already known from antiquity for coloring body and hair. These dyeings are usually prone to shampooing, so that sometimes after a few washes an undesirable nuance shift or even a visible "discoloration" occurs.
  • oxidation colorants For permanent, intensive dyeings with corresponding fastness properties, so-called oxidation colorants are used. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components. The developer components form under the influence of oxidizing agents or of atmospheric oxygen with one another or with coupling with one or more coupler components, the actual dyes.
  • the oxidation stains are characterized by excellent, long lasting staining results.
  • a mixture of a larger number of oxidation dye precursors must usually be used; In many cases, direct dyes are still used for shading.
  • the colorants of the three categories described in the form of creams, gels or solutions are usually applied to the fibers with the aid of a brush.
  • dyes that are applied to the fibers as a shampoo formulation or conditioner formulation. In all these types of applications, the resulting scalp staining plays a major role, which is considered disadvantageous.
  • DE 199 22 092 A1 describes, for example, a cap-like application device for dyeing hair strands, which is placed on an associated container with hair dye.
  • This application device comprises a plurality of outlet openings for applying the hair dye and adjacent thereto guide prongs, which are drawn during use with combing movements through the hair.
  • bristles are arranged around the outlet opening in order to achieve a more uniform application of the hair dye. Nevertheless, the outlet openings with the bristles do not allow a sufficiently metered application of the hair dye. In particular, an excessive leakage of the hair dye and thus also an unwanted wetting of the scalp can not be effectively excluded.
  • the object of the present invention was therefore to develop a dyeing system which makes it possible to combine the advantages of an application device containing a dye based on substantive dyes (simple applicability and low scaling) with the durability of a dyeing agent based on oxidation dye precursors.
  • a first subject of the present invention is therefore an application device for applying an application liquid to keratinic fibers, in particular hair, with at least one container for receiving the application liquid, with an application head which is connected to the at least one container and has a porous application body for applying the Application liquid by sweeping the fibers, wherein the application liquid contains at least one precursor of a natural analog dye.
