摘　　要：制备 6种不同剂型的油乳剂,将油乳剂分别在常温(2 0 - 2 3℃)、冷藏(4℃)、冷冻( - 2 0℃)后融化处理,测定各油乳剂经不同处理后的表面张力、分散相粒度及均匀度和油乳剂的稳定性,分析测定结果。试验表明:油乳剂 3(W/O 1 2 )、4(W/O 1 3)相关指标较优。同时表明冷藏对油乳剂物理性状有一定影响,冷冻可大大降低油乳剂的稳定性。kinds of oil emulsion were adopted to determine such physical characters as surface tension,grain density, uniformity and stability.Firstly,the oil emulsion under three different conditions,that is,normal temperature(20～23℃),refrigerating temperature(4 ℃), and freezing temperature(-20 ℃) melt,and then the results were analysed.The results show that the related indexes of the sample 3(W/O 12) and the sample 4(W/O 13) are better than the others. Meanwhile,the refrigerating temperature has some influences on the physical characters of oil emulsion, and the freezing temperature can greatly decrease the stability and quality of the oil emulsion.
