The invention relates to clear, liquid preservatives, which contain a) one or several 1-hydroxy-4-methyl-6-alkyl-2(1H)-pyridones and/or one or several salts thereof, wherein alkyl represents a linear, branched or cyclic alkyl group having 1-12 carbon atoms, and b) one or several alcohols containing one or several aromatic groups.

Preservatives

The invention provides water-soluble or water-swellable copolymers obtained by free-radical copolymerization of

Silicone-modified comb polymers based on acryloyldimethyltaurine acid (2-acrylamido-2-methyl-1-propanesulfonic acid)

The invention provides water-soluble or water-swellable copolymers obtained by free-radical copolymerization of The water-soluble or water-swellable copolymers of the present invention are useful in formulating cosmetics.

Cationically modified comb polymers based on acryloyldimethyl taurine acid

Cosmetic, dermatological and pharmaceutical compositions containing quaternary ammonium compounds, particularly for hair-treatment, require low setting points, good solubility and dispersibility in aqueous media and a low flash point. It has now been found that such compositions can be formulated with quaternary ammonium compounds and polyhydric alcohols. The invention provides compositions comprising

Cosmetic formulations of quaternary ammonium compounds incorporating polyhydric alcohols

Cosmetic, dermatological and pharmaceutical compositions containing quaternary ammonium compounds, particularly for hair-treatment, require low setting points, good solubility and dispersibility in aqueous media and a low flash point. It has now been found that such compositions can be formulated with quaternary ammonium compounds essentially free of short-chain alcohols such as isopropanol. The novel composition comprises:

Cosmetic formulations of quaternary ammonium compounds free of short-chain alcohols

The invention provides compositions comprising The compositions have low setting points, good solubility and dispersibility in aqueous media and a low flash point.

Cosmetic formulations of having high aqueous solubility and low flash points

The invention relates to aqueous hair-treatment compositions comprising one or more quaternary ammonium compounds which are sparingly soluble in water and which contain at least one long-chain alkyl or alkenyl group having at least 18 carbon atoms, one or more water-soluble quaternary ammonium compounds, one or more nonionic, amphoteric and/or zwitterionic solubility promoters and optionally one or more thickeners. The compositions according to the invention are distinguished by a clear and translucent appearance. In particular, the compositions are hair cures and hair rinses.
