水/油/水(w/o/w)复乳是一种复合的体系。制备时至少需要两种表面活性剂。低HLB值的表面活性剂用于制备初乳,高HLB值的表面活性剂用于二次乳化。本文研究用阿拉伯胶、明胶和聚乙烯吡咯烷酮(PVP)作为复乳内相,用山梨醇单油酸酯为表面活性剂制备一种稳定的复乳。复乳(w/o/w)制备,系用10mg/ml的氯喹磷酸盐和2%(w/v)的高聚物(如阿拉伯胶、明胶和PVP)水溶液为内相,经与10%(w/v)司盘80的豆油溶液乳化后制成w/o初乳,再将等体积的上述初乳和1%吐温80的水溶液进行第二次乳化而成。试验系用显微
Water / oil / water (w / o / w) Multiple emulsion is a complex system. At least two surfactants are required for preparation. Low HLB surfactants are used for the preparation of colostrum and high HLB surfactants for the secondary emulsification. In this paper, the use of acacia, gelatin and polyvinylpyrrolidone (PVP) as double emulsion internal phase, sorbitol monooleate as surfactant to prepare a stable double emulsion. A double emulsion (w / o / w) was prepared using 10 mg / ml of chloroquine phosphate and 2% (w / v) of an aqueous solution of polymer such as acacia, gelatin and PVP as the internal phase, (w / v) Span 80 soya oil solution made of emulsified w / o colostrum, and then an equal volume of the above colostrum and 1% Tween 80 aqueous solution made from the second emulsion.
