Description

The invention is in the field of cosmetics and relates to surfactants and specific alums containing essentially sodium-free hair treatment agents, a process for stabilizing potassium aluminum sulfate in hair treatment agents and the use of sodium-free hair treatment agents and others. to strengthen the inner hair structure.

Products for changing the natural hair color play an outstanding role in hair cosmetics. However, hair colors artificially produced by coloring systems have the disadvantage that they can change - for example during or after hair cleaning - in an undesirable manner, which primarily means the fading or bleeding out and the loss of color brilliance of the color shade achieved. Environmental influences and / or sun exposure can intensify these color changes.

Classic hair cleaners mostly contain anionic surfactants as primary surfactants due to their excellent foam properties and cleaning effect. In higher amounts, these can have the disadvantage that they soften the scalp and remove lipids from the outer layers of the skin. Particularly sensitive skin can become dry, brittle and sometimes cracked after frequent cleaning with commercially available shampoos, unless lipids in the form of hair conditioners are added to it after or during cleaning.
Most commercially available anionic surfactants are offered as a solution in the form of their alkali salts. It has been found that repeated contact with solutions containing alkali metals can result in a significant increase in hair swelling and a decrease in the denaturing temperature of hair. These parameters serve as indicators when determining the condition of the inner hair structure.
The often repeated use of conventional hair shampoos can therefore further damage the inner hair structure (especially by coloring already damaged and / or damaged hair).

Accordingly, there is a need for cosmetic hair treatment agents, in particular for hair cleaning agents, which improve the washing resistance of artificially produced hair colors without straining the scalp and / or the hair.

Alums for color protection and for the relief of hair damage caused by the use of alkaline hair treatment agents have already been described in the past ( DE 102014226176 and EP 589373).

However, it has now been found that potassium, ammonium and / or guanidinium aluminum sulfate show particularly good results with regard to the positive influence on the hair structure and the wash resistance of artificially produced hair colors.

A problem with the use of potassium, ammonium and / or guanidinium aluminum sulfate in hair treatment compositions, in particular in hair cleansing agents, is, however, that potassium, ammonium and / or guanidinium aluminum sulfate react in conventional hair cleaning agents containing sodium ions to form the more soluble sodium aluminum sulfate, which increases and dissociates leads to increased susceptibility to hydrolysis of the aluminum in the double salt. This can lead to the precipitation of aluminum hydroxide and thus to reduced effectiveness.

The aim of the invention was thus to provide hair treatment agents (optimally hair cleaning agents) in which potassium, ammonium and / or guanidinium alum are better stabilized, so that the tendency to wash out artificially produced hair colors and the protection of the inner hair structure can be improved even further.

It has surprisingly been found that the above-mentioned goals are achieved to an excellent degree when potassium, ammonium and / or guanidinium alum are used in hair treatment compositions containing anionic and / or amphoteric surfactants which are essentially free of compounds containing sodium ions.
The use of such hair treatment agents results in a significantly improved scalp tolerance of the agents and a lower tendency to swell the hair, as a result of which the inner hair structure is protected or restabilized.
The use of such hair treatment agents also results in a greatly reduced tendency to wash out artificially produced hair colors.
