摘　　要：运用两步乳化法制备油包水包油(O/W/O)型多重结构乳状液,研究了乳化剂种类、乳化剂用量、相体积比和添加剂等因素对O/W/O多重结构乳状液的形成和稳定的影响。实验结果表明,O/W脂肪醇聚氧乙烯醚-21EO(S21)、聚氧乙烯-聚氧丙烯嵌段共聚物(F127)以及W/O环甲基硅氧烷(及)PEG/PPG-18/18聚二甲基硅氧烷(DC5225)的最佳质量分数均为5%;当内油相的Si-451质量分数为15%、水相的Si451质量分数为30%时是形成多重结构乳液的最佳质量分数;质量分数为2%的单甘酯(GMS)对多重结构的形成和稳定起着重要的作用;1,3-丁二醇的加入有效地提高了多重结构稳定性。O/W/O Multiple emulsions was prepared by two-step emulsion method.The effects of emulsifier type,emulsifier concentration,phase volume ratio and additives on the formation and stability of O/W/O multiple emulsions particles were studied.The experimental results showed that the optimum mass fraction of hydrophilic emulsifier steareth-21(S21),poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol)(F127)and lipophilic emulsifier cyclopentasiloxane(and)PEG/PPG-18/18 Dimethicone(DC5225)were all 5%;the Si-451 mass fraction of inner oil phase was 15%,and the mass fraction of water phase was 30%,which was the best phase volume ratio to form multiple emulsions.The 2%mass fraction of monoglyceride(GMS)played a very important role in the formation and stabilization of multiple emulsions,and the addition of butane-1,3-diol can effectively improve the stability of multiple emulsions.
