Description

Detailed Description of the Invention

[0001]

The subject of the present invention is a special dye carrier material and the oxidation of hair with improved hair properties which is obtained by mixing such a dye carrier material with an oxidizer formulation. It is a dyeing agent.

[0002]

Oxidized hair dyes are an important component of cosmetic product sets used in all hair treatments. These consist of two components, both of which are mixed with each other just before use and then applied on the hair to be dyed.

This first component is a dye carrier material (Fa
rbstofftraeger masse) and contains a dye. It can exist as a liquid or gel,
In particular, it may be present as an emulsion.

However, the emulsion-like dye carrier substances known hitherto have a series of disadvantages, in particular with regard to their hair-dressing effect. That is, such agents achieve only poor combability improvements, for example when wet and dry, and furthermore, after a single hair wash, the conditioning effect generally has already disappeared. Will return to.

[0005]

The object of the present invention is therefore that of emulsions which exhibit stable and homogeneous emulsions as well as optimum viscosities and which, in addition, lead to very good and durable hair conditioning. An object of the present invention is to provide a oxidative dyeing agent for hair, which is mainly composed of a dye-like carrier material.

Here, anionic and / or nonionic surfactants, aliphatic alcohols and / or fatty acid esters, and an emulsion dye carrier substance containing glyceryl monooleate and / or lanolin as a main component are used. It has been found that the above requirements are met very well when used.

[0007]

The object of the present invention is therefore (a) water, (b) an oxidative dye precursor and optionally a dye which is further applied directly on the hair, (c) a fat. Emulsion dye containing fatty acid saturated with group alcohol and / or glycerin ester, (d) anionic and / or nonionic and / or amphoteric surfactant, and (e) lanolin and / or glyceryl monooleate It is a carrier material.
