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

Particulate bleach activators comprising 15 to 60% by weight of an acetonitrile, 20 to 70% by weight of a silicon-containing carrier material and 20 to 30% by weight of water, which are obtained by applying an aqueous solution, saturated at 10 to 40&deg; C., of an acetonitrile onto the carrier material without subsequent drying, where the amount of saturated aqueous solution is measured such that the given limits for acetonitrile, carrier material and water are observed.
