洗发水表面活性剂研究进展

The Research Progress of Surfactant in Shampoo

本文介绍了洗发水表面活性剂月桂醇聚醚硫酸酯盐类、氨基酸盐类表面活性剂,非离子糖苷类表面活性剂的详细性能。月桂醇聚醚硫酸酯盐发泡、稳泡及絮凝性能佳,但其含有二噁烷,温和性欠佳而广受诟病;氨基酸盐类表面活性剂因其泡沫丰富,性能温和而成为后起之秀,但该类表面活性剂增稠较为困难,絮凝较慢,洗后头发不够顺滑;非离子烷基糖苷类表面活性剂对皮肤相容性佳,更加温和绿色,引起广泛关注。

This paper introduces the detailed performance of shampoo surfactants,which include lauryl polyether sulfate salts,amino acid salts,and nonionic glycosides surfactants.Lauryl polyether sulfate salts have good foam stabilization and flocculation performance,but they are widely criticized for containing dioxane and having poor mildness;amino acid salts surfactants have became highlights,because of their rich foam and mild performance,but they are more difficult to be thickened and flocculate slowly,and the hair is not smooth enough after washing;nonionic glycosides surfactants are more compatible with skin and more mild and environment friendly,which have attracted wide attention.
