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.
含有季
铵盐化合物的化妆品、皮肤剂和药剂组合物,尤其是用于头发处理的组合物,要求凝固点低,在
水介质中具有良好的溶解性和分散性,闪点低。现在发现,可以用基本上不含短链醇(如
异丙醇)的季
铵化合物来配制这类组合物。这种新型组合物包括
a) 至少一种季
铵盐化合物和
b) 至少一种具有 8 至 36 个碳原子的支链醇,或至少一种支链醇和至少一种具有 8 至 36 个碳原子的非支链醇的混合物。
