  • oxidation colorants are used for permanent, intensive colorations with corresponding fastness properties.
  • Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components which under the influence of oxidants or of atmospheric oxygen form the actual dyes with one another.

  • dyeing or toning agents which contain what are known as substantive dyes ("direct drawers") as coloring components, which can also be used together with oxidizing agents in brightening dyes.
  • oxidative colorants In order to develop optimal dyeing performance, oxidative colorants generally require an alkaline pH for coloration, in particular between pH 9.0 and pH 11.5.
  • oxidative colorants are usually prepared just prior to use by mixing a color change formulation and an oxidizer formulation.
  • the color change preparation usually has an alkaline pH for stabilizing oxidation dye precursors and the oxidizing agent preparation has an acidic pH for stabilizing the oxidizing agent while the application mixture should have an alkaline pH in order to ensure good penetration of the dye precursors and the oxidizing agents to allow the keratinic fiber.
