Definitions

  • the present invention relates to agents for coloring keratin fibers and their use and a corresponding hair dyeing process.
  • the compositions contain at least one dye precursor for a nature-analogous dye selected from the group of indole or indoline derivatives, at least one organic compound which carries at least one thiol group in the molecule and at least one alkalizing agent, are free of additional oxidizing agents and do not contain the oxidation the color-forming components catalyzing enzyme.
  • 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 coupler components.
  • the developer components form the actual dyes under the influence of oxidizing agents or of atmospheric oxygen with one another or with coupling with one or more coupler components.
  • the oxidation dyes are characterized by excellent, long-lasting dyeing results. For naturally acting dyeings, however, usually a mixture of a larger number of oxidation dye precursors must be used; In many cases, direct dyes are still used for shading.
  • the developer components used are usually primary aromatic amines having a further, in the para or ortho position, free or substituted hydroxy or amino group, heterocyclic hydrazones, diaminopyrazole derivatives and 2,4,5,6-tetraaminopyrimidine and its derivatives.
  • Coupler substances are 1-naphthol, 1,5-dihydroxynaphthalene, 2,7-dihydroxynaphthalene, 1,7-dihydroxynaphthalene, 5-amino-2-methylphenol, m-aminophenol, resorcinol, resorcinomonomethyl ether, m-phenylenediamine, 1-phenyl 3-methyl-pyrazol-5-one, 2,4-dichloro-3-aminophenol, 1, 3-bis (2,4-diaminophenoxy) -propane, 2-amino-3-hydroxypyridine, A-chlororesorcinol , 2-chloro-6-methyl-3-aminophenol, 2-methylresorcinol, 5-methylresorcinol and 2-methyl-4-chloro-5-aminophenol.
  • dyeing or tinting agents which contain so-called direct drawers as a coloring component. These are dye molecules that attach directly to the substrate 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 generally much more sensitive to shampooing than the oxidative dyeings, so that a much more undesirable change in shade or even a visible, homogeneous color loss occurs much more quickly.
  • a first class of oxo dye precursors are compounds having at least one reactive carbonyl group. This first class is called a component (Oxo1).
  • a second class of oxo dye precursors form CH-acidic compounds and compounds having primary or secondary amino groups or hydroxy groups, which in turn are selected from compounds of the group formed from primary or secondary aromatic amines, nitrogen-containing heterocyclic compounds and aromatic hydroxy compounds. This second class is called a component (Oxo2).
  • the aforementioned components (oxo1) and (oxo2) are generally not themselves dyes, and therefore are not in themselves suitable for coloring keratin-containing fibers. In combination, they form dyes in a non-oxidative process of so-called oxo dyeing. The resulting dyeings have partially color fastness on the keratin-containing fiber, which are comparable to those of the oxidation dyeing.
  • the Nuancenspektrum achievable with the gentle oxo staining is very broad and the color obtained often has an acceptable brilliance and color depth.
  • the method of oxo staining can be readily combined with the oxidative staining system. If substrates are to be lightened or even bleached, they will stain the substrate
  • Dyes usually oxidative using appropriate oxidizing agents, such as hydrogen peroxide, decolorized.
  • precursors of the natural hair dye melanin are applied to the substrate, e.g. Hair, applied; These then form naturally-analogous dyes in the course of oxidative processes in the hair.
  • multiple use of agents with 5,6-dihydroxyindoline it is possible to reproduce natural hair color to people with graying hair.
  • the coloration can be done with atmospheric oxygen as the sole oxidant, so that no further oxidizing agents must be used.
  • the indoline can be used as the sole dye precursor.
  • satisfactory results can often only be achieved for use in persons with originally red and, in particular, dark to black hair color, by using other dye components, in particular special oxidation dye precursors.
  • the dyeing is carried out using the precursors for nature analog dyes gently with atmospheric oxygen.
  • the dye precursors on indole or indoline base usually used are incorporated for this purpose in a cosmetic carrier, which preferably has a basic pH.
  • the coloration according to this method results in a natural coloration of the keratin-containing fiber, which, however, especially in the brown and blond area has a slight reddish, bluish or violet color nuance. If additional oxidizing agents are used in the colorants, these color shifts occur negligibly or even not at all.
  • Dyes based on nature-analogous dyes appeal to those consumers who want to gently restore their gray hair to a natural hair color.
  • the aforementioned color shift is undesirable especially for this consumer. Therefore, the coloration with natural dyes is in this respect in need of improvement.
  • hair dyes based on dye precursors of the indole or indoline type are known, which additionally contain at least one amino acid or an oligopeptide to improve the colorations on grayed hair.
  • the dyeings obtained on blond hair all have an undesirable red or blue cast.
  • hair dyes which, in addition to a dye precursor of the indoline type, 0.05 to 5 wt.% Of at least one oxidation dye precursor of the developer type and 0.05 to 5 wt.% At least one Coupler type oxidation dye precursor. It was found that the

  • Object of the present invention is therefore to provide a colorant based on natural dyes, which, especially after prolonged storage, with keratin fibers under air oxidation, color-intense natural blond, brown or black tones gives.

Abstract

L'invention concerne des colorants contenant au moins un précurseur de colorant pour un colorant de type naturel, choisi dans le groupe des dérivés d'indole ou d'indoline; au moins un composé organique portant au moins un groupe thiol dans la molécule; et au moins un agent d'alcalisation. Lesdits colorants sont exempts d'agents d'oxydation supplémentaires et d'enzymes catalysant l'oxydation des constituants colorants. Les colorants selon l'invention produisent des colorations plus intenses sur des substrats kératiniques.
