Abstract

Recently, amphiphilic polymers have come to actual use as an emulsifying agent in oil industries. They can provide stability and reduce an amount of low-molecular-weight surfactants. They stabilize emulsions by “adsorption at an oil and water interface” and/or “associating thickening”. This over view summarizes several types of polymeric emulsifier and emulsification mechanism mainly in cosmetic field and describes recent studies of a new water-soluble amphiphilic polysaccharide HHMHEC. HHM-HEC formed a gel through aggregation of hydrophobic moieties in water and stabilized O/ W emulsions by the associative thickening mechanism.

两亲性聚合物乳化
近年来,两亲性聚合物作为乳化剂在石油工业中得到了实际应用。它们可以提供稳定性并减少低分子量表面活性剂的用量。它们通过“在油水界面的吸附”和/或“缔合增稠”来稳定乳剂。本文综述了化妆品领域常用的几种聚合物乳化剂及其乳化机理,并介绍了一种新型水溶性两亲性多糖hmhec的研究进展。HHM-HEC通过疏水基团在水中聚集形成凝胶,并通过缔合增稠机制稳定油水乳状液。
