化妆品中W/O型乳化体性能的研究

Study on the Property of Water-in-oil Emulsion in Cosmetic

通过对所制备的W/O型乳化体系的外观、肤感以及耐寒、耐热稳定性的测试,系统地考察了影响W/O型乳化体性能的各个因素,并把优选的W/O型乳化体配方作为基质制成防晒霜。实验表明:在等量防晒剂下,W/O型防晒霜比O/W型防晒霜具有更加优良的防晒和防水防汗能力。

Some factors which affected the water-in-oil emulsion were inspected by test the outward appearance, kin feeling as well as the ability of cold-resisting and heat-resisting of the water-in-oil emulsion in the paper. Some factors associated with formulation include the nature and the dose of emulsifier, the nature and composition of oil phase, the nature and the dose of co-emulsifier in water phase and the ratio of the two phase. The other factors associated with processing include method of adding ingredient, emulsifying temperature and particlesized was tribution. It was also reported that using water-in-oil emulsion to produce water-in-oil emulsion had many good functions. And it had proved that water-in-oil sunscreen emulsion had better functions of anti-sunburning and water-proofing than oil-in-water sunscreen emulsion.
