  • Patent number: 6919074
    Abstract: 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: a) at least one quaternary ammonium compound and b) at least one branched alcohol having 8 to 36 carbon atoms or a mixture of at least one branched alcohol and at least one unbranched alcohol having 8 to 36 carbon atoms.
