Further described is a process for the preparation of a composition according to the invention.

Cosmetic compositions comprising fatty acid N-alkylpolyhydroxyalkylamides and fatty alcohols for the care of the skin and hair are known.

The funds are characterized by an improved soft feel of the hair and a particularly pleasant skin feeling. Specifically disclosed are examples of fatty acid N-alkylpolyhydroxyalkylamides derived from coconut fatty acid.

The WO 94/21226 discloses detergent mixtures containing polyhydroxy fatty acid amides, monomeric cationic surfactants, fatty alcohols and optionally oil bodies, hair treatment compositions containing these mixtures and the use of the mixtures for the preparation of hair treatment compositions. Specifically disclosed are examples of C12 / 14 fatty acid N-alkyl polyhydroxyalkylamides.

In the WO 96/27366 discloses cosmetic and pharmaceutical compositions containing as O / W emulsifiers fatty acid-N-alkylglucamide in combination with fatty alcohols as Coemulgatoren. An indication of conditioning effect in hair care is not found.

In the WO 92/05764 Shampoos are described which contain, inter alia, glucamides and dimethicone.

Although good results have already been achieved with the known compositions, there is nevertheless a broad scope for improvement, in particular as regards use in shampoos.

Task was, for example, to develop compositions that are well formulated and allow increased silicone position, especially when used as a shampoo.

It has been found that this object is achieved by compositions containing at least one N-alkyl-N-acylglucamine, dimethiconol and at least one anionic surfactant.
