In this study, the influence of polyols, emulsifiers and oils on the formation and stability of polyol-in-oil (P/O) emulsions was investigated. The interfacial tension in P/O systems is much lower than that of water-oil systems, so polyols and oils showed a greater affinity, which was not conducive to the stability of the emulsion system. High compatibility of the emulsifier and the inner and outer phases was the key to the formation of stable emulsions. Using polyethylene glycol 400 (PEG) as polyol phase, mineral oil or squalane as oil phase and cetyl PEG/PPG-10/1 dimethicone (EM 90) as emulsifier, long-term stable P/O emulsions with homogeneous droplets were successfully prepared.

油包多元醇乳液的形成及稳定性研究

在这项研究中,研究了多元醇、乳化剂和油对油包多元醇 (P/O) 乳液的形成和稳定性的影响。P/O体系的界面张力远低于水油体系,因此多元醇和油类表现出较大的亲和性,不利于乳液体系的稳定。乳化剂与内外相的高度相容性是形成稳定乳液的关键。以聚乙二醇400(PEG)为多元醇相,矿物油或角鲨烷为油相,鲸蜡基PEG/PPG-10/1聚二甲基硅氧烷(EM 90)为乳化剂,成功制备了长期稳定的均相P/O乳液。
