摘要
制备了含约3 wt%不同助表面活性剂的洁面膏,包括阴离子、两性基和非离子表面活性剂.测试结果表明,椰油酰两性基乙酸钠降低体系的结膏点和储能模量,月桂基羟基磺基甜菜碱和PEG-12甲基葡糖二油酸酯提升体系的结膏点和储能模量;除了椰油酰两性基乙酸钠和PEG-120甲基葡糖二油酸酯降低体系的发泡力,其余助表面活性剂均在不同程度上提升发泡力;PEG-120甲基葡糖二油酸酯会增加体系的硬度、粘性和粘力,并且月桂醇聚醚-4也会提升样品的粘性和粘力;PEG-120甲基葡糖二油酸酯会提升对皮脂的清洁力.
Abstract
A facial cleanser containing about 3 wt%of different cosurfactants was prepared,including anionic,amphoteric and non-ionic surfactants.The results showed that sodium cocamoylamphoacetate decreased congealing point and energy storage modulus,while lauryl sulfobetaine and PEG-12 methyl gluco dioleate increased both.However,with cosurfactants sodium cocoamphoacetic acid or PEG-120 methyl gluco dioleate,the foaming capacity was reduced,while the other cosurfactants increased the foaming capacity to varying extents.Meanwhile,PEG-120 methyl glucose dioleate increased the hardness,viscosity and adhesion,as well as lauryl ether-4 increased viscosity and adhesion in the facial cleanser sample.In addition,PEG-120 methyl gluco dioleate enhanced the removal of sebum in the detergency test.
