制备了水、Tween-80/L-7D(吐温80/十聚甘油月桂酸酯)、甜橙油和丙二醇的微乳液.利用三元相图,比较了Tween-80、L-7D这两种乳化剂对微乳区形成大小的影响,考察了微乳液的稳定性和粒径大小.结果表明,在该试验条件下,Tween-80更适合于制备微乳,利用三元相图配制的微乳,可自发形成且稳定性好,粒径小于100 nm.%Sweet orange oil micro-emulsion composed of water, Tween-80/L-7D, sweet orange oil, propylene glycol was prepared using ternary phase diagram. The stability of micro-emulsion also was tested. The results showed that tween-80 was more suitable for the formation of micro-emulsion than L-7D under the conditions of this study, the micro-emulsion prepared by following the ternary phase diagram could form spontaneously and had good stability, its particle size was less than 100 nm.
