Definitions

  • the invention relates to a process for fiber-sparing dyeing of keratin-containing fibers, which is characterized by a two-stage application, wherein in a first step, a dyeing preparation containing a fiber structure-improving agent is applied to the hair, is rinsed out of the hair after a certain exposure time and in a second step, which adjoins the first stage of the process in a timely manner, an aftertreatment agent is applied which contains at least one biochinone active ingredient. Due to the specific combination of active ingredients in the dyeing preparation and after-treatment agent, an unexpected fiber structure improvement is achieved. Furthermore, the present invention relates to a packaging unit which contains a hair dyeing preparation and an aftertreatment agent containing a biochinone active ingredient. The use of the packaging unit makes it possible to achieve an excellent fiber structure improvement, in particular with regard to the fiber thickness.
  • Changing the shape and color of the hair is an important area of modern cosmetics. This allows the hair's appearance to be adapted to current fashion trends as well as to the individual wishes of the individual.
  • the consumer accesses to color-changing agents. In addition to the desired dyeing power, these agents should cause the least possible damage to the hair and protect the fiber structure.
  • oxidation colorants For permanent, intensive colorations with corresponding fastness properties, so-called oxidation colorants are used. Such colorants usually contain oxidation dye precursors, so-called developer components and
  • 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 dyes are characterized by excellent, long-lasting dyeing results.
  • For naturally acting dyeings usually a mixture of a larger number of oxidation dye precursors must be used; In many cases, direct dyes are still used for shading.
  • For temporary dyeings usually dyeing or tinting agents are used, which contain as coloring component so-called substantive dyes (direct drawers). These are dye molecules that attach directly to the substrate and do not require an oxidative process to form the paint.
  • a first class of oxo dye precursors are compounds having at least one reactive carbonyl group.
  • a second class of oxo dye precursors form C, H-acidic compounds and compounds having a primary or secondary amino group or hydroxy group, preferably aromatic compounds.
  • the resulting dyeings have partially color fastness on the keratin-containing fiber, which are comparable to those of the oxidation dyeing, but without relying on oxidizing agent for dye formation.
  • the dyes coloring the substrate are usually decolorized oxidatively using appropriate oxidizing agents, for example hydrogen peroxide.
  • oxidative hair dyes are disadvantageous to the user despite their advantageous dyeing properties.
  • the use of the oxidizing agent for coloration or development of the actual coloration leads to damage in the hair structure and on the hair surface. The hair becomes brittle, its elasticity decreases and its fiber strength decreases.
  • the object of the present invention is therefore to lower the mentioned disadvantages of hair dyeing processes.
  • the fiber structure should be spared as possible, so that their Elasticity is as little as possible affected by the color change agent, and that the fibers have the least possible deterioration of the fiber thickness.
  • a first subject of the present invention is therefore a process for changing the color of keratinic fibers, wherein a dyeing preparation is applied to the fibers in a first step, is left on the fibers for a contact time T1 and subsequently washed out, and in a second step a post-treatment agent is applied to the keratinic fibers, is left on the fibers for a contact time T2 and is subsequently washed out, characterized in that a) the dyeing preparation in a cosmetic carrier contains at least one color-modifying component and additionally at least one fiber-structure-improving agent, b) the period a maximum of 60 minutes between completion of the first process step and beginning of the second process step, and c) the aftertreatment agent in a cosmetic carrier contains at least one active ingredient selected from biochinones.
