摘　　要：通过动态光散射法(DLS)研究了不同表面活性剂(CAB、2000UP、TW-28、20HD、810、CGT30、K-SF、AES)及其与AES复配体系的胶束粒径大小和温和性,发现非离子和两性表面活性剂与阴离子表面活性剂AES复配均可增大AES体系胶束粒径,降低AES体系刺激性,其中PEG-80失水山梨醇月桂酸酯可明显增大胶束的粒径大小,同时帮助减少清洁体系中表面活性剂对皮肤角质层的渗透,降低对皮肤的刺激反应。The micelle size and mildness of different surfactants(CAB,2000UP,TW-28,20HD,810,CGT30,K-SF,AES)and their complex systems with AES were studied by dynamic light scattering(DLS).It was found that the combination of non-ionic and amphoteric surfactants with anionic surfactant AES can increase the micelle size of AES system and reduce its irritancy.Among them,PEG-80 dehydrated sorbitol lauric acid ester can significantly increase the micelle size,at the same time,help to reduce the penetration of surfactants into the stratum corneum of the skin in the cleaning system,as well as reduce the irritation response to the skin.
