Definitions

  • the invention relates to an agent for oxidative hair coloring, which continuously releases care substances during the application time.
  • Preparations for tinting and coloring hair are an important type of cosmetic products. They can be used to shade the natural hair color slightly or more depending on the wishes and needs of the person concerned, to achieve a completely new hair color or to cover up undesirable shades, such as shades of gray.
  • conventional hair dyes are formulated either on the basis of oxidation dyes or on the basis of substantive dyes. Combinations of oxidation dyes and direct dyes are often used to achieve special shades.
  • Good dyes are characterized by a high color strength. Good sweat, heat, perm, wash and light fastness are also desired. They should also be safe from a toxicological and dermatological point of view. It is also advantageous if the substances have a high solubility in various base formulations.
  • Colorants based on oxidation dyes lead to brilliant and lasting shades.
  • they are generally applied to the hair to be colored at alkaline pH values from 8 to 11 and before or after application to the hair with a chemical oxidizing agent, usually hydrogen peroxide, a per-compound or a hydrogen peroxide adduct , activated, ie polymerized oxidatively to the dye.
  • a chemical oxidizing agent usually hydrogen peroxide, a per-compound or a hydrogen peroxide adduct , activated, ie polymerized oxidatively to the dye.
  • Such treatment particularly with repeated use or if the hair has already been damaged by other treatments, can result in damage to the hair structure, resulting in poor combability and malleability and a loss of shine.
  • Elasticity and tear-resistant activity expresses.
  • such a treatment can give the hair an overall unkempt and unattractive appearance.
  • WO89 / 06531 shows the oxidative coloring of hair with an alkaline agent which is formed immediately before use by the mixing of two components, one containing the oxidation dye precursors and the other the oxidizing agent. At the time of its creation, this agent also contains microencapsulated active ingredients, which dissolve after mixing and ensure gentle oxidative hair coloring at weakly alkaline pH values.
  • the object of the invention was therefore to develop a means for oxidative hair coloring, with which the hair can be gently oxidatively colored while avoiding the disadvantages mentioned above.
  • the method should in particular damage healthy and / or further damage to previously damaged hair minimized by the oxidative treatment and the hair can be supplied with hair care and restructuring agents without a further, time-consuming step, in order to additionally counteract hair damage.
  • This object has been achieved by developing an oxidative hair dye which ensures the continuous release of intact hair care and restructuring components during the entire application time and thus reduces hair damage during the oxidative treatment.
  • the invention thus relates to an agent for oxidative hair dyeing with continuous release of at least one care substance.
