摘　　要：研究了亲脂性表面活性剂的性质和用量对W/O/W型复合乳状液稳定性的影响,采用两种类型的亲脂性表面活性剂:新型的聚合型高分子表面活性剂聚氧乙烯(30)二聚羟基硬脂酸脂(ArlacelP135)和传统的小分子表面活性剂Span80和Tween80的混合物(质量比9∶1,HLB=5.4)制备复乳。采用离心保留率、光学显微镜和黏度等方法评价初乳和复乳的稳定性。结果表明,与小分子表面活性剂Span80和Tween80的混合物相比,大分子聚合表面活性剂ArlacelP135可以显著地提高复合乳状液的稳定性,在优化的条件下复乳的稳定性可以达到2000r/min离心15min不分层。In this study, the influences of type and concentration of the lipophilic emulsifier on the W/O/W multiple emulsion＇s stability were investigated. Two types of lipophilic emulsifier.. macromolecular surfactant PEG-30 Dipolyhydroxystearate （Arlacel P135）, mixture of small molecular surfactant Span80 and Tween80（weight ratio=9 ： 1） were used as lipophilic emulsifier to prepare multiple emulsion. Centrifugal creaming volume, light microscopy and viscosity were used to estimate the emulsion＇s stability. The results presented have indicated that macromoleculer surfactant Arlacel P135 significantly improve the multiple emulsion＇s stability compared to that of the mixture of Span80 and Tween80.
