The NIE and the AIE selected are mixed in various proportions and,by using the concept of additivity for HLB values of surfactant mixtures,the optimal proportion of the NIE an the AIE is determined from O/W emulsion viscosity vz HLB value relationships.

• 选定的一对非离子和阴离子乳化剂按不同比例复配,利用混合表面活性剂HLB值的加和性原理,由O/W乳状液黏度-HLB值关系确定二者最佳配比。
