A method of imparting improved conditioning properties to hair which comprises treating the hair with a composition comprising a water-soluble quaternary ammonium compound, such as cetrimonium chloride; an oil-soluble, water-dispersible quaternary ammonium compound, such as distearyldimonium chloride; and acid-neutralised amidoamine compound; and a low lolecular weight polydimethylsiloxane compound, such as cyclomethicone. Th amidoamine has the general formula:
wherein R₁ is a fatty acid chain containg from 11 to 21 carbon atoms, R₂ is an alkylene group containing from two to four carbon atoms, R₃ is hydrogen, methyl, ethyl or a hydroxyalkylene group containing from one to three carbon atoms, R₄ is methyl, ethyl or a hydroxyalkylene group containing from one to three carbon atoms, and Y is heterocyclic nitrogen-containing moiety, like morpholine or pyridine, and is neutralised with a suitable acid. A suitable amidoamine compound is stearamidoethylethanolamine neutralized with phosphoric acid.
一种改善头发调理性能的方法,包括用一种组合物处理头发,该组合物包括水溶性季铵盐化合物,如西曲铵盐;油溶性、水分散性季铵盐化合物,如二硬脂基氯化铵;酸中和的氨基胺化合物;以及低分子量的聚二甲基硅氧烷化合物,如环甲基硅氧烷。氨基胺的通式如下
其中 R₁ 是含有 11 至 21 个碳原子的脂肪酸链,R₂ 是含有 2 至 4 个碳原子的亚烷基,R₃ 是氢、甲基、乙基或含有 1 至 3 个碳原子的羟基亚烷基、R₄ 是甲基、乙基或含有一至三个碳原子的羟基烷基,Y 是含氮杂环分子,如吗啉或吡啶,并用适当的酸中和。一种合适的氨基胺化合物是用磷酸中和的硬脂氨基乙基乙醇胺。
