【摘要】 以硬脂酸蔗糖酯和失水山梨醇硬脂酸酯的复配物 (SSE)为主乳化剂 ,十六 /十八醇及甘油为助乳化剂制备含液晶乳液化妆品。通过观察乳液的温度稳定性和液晶性 ,用三元相图研究助乳化剂含量对此乳液体系液晶区的影响。实验条件下 ,用该乳化剂体系可获得较好的液晶化妆品乳液。总之 ,较高的助乳化剂量有利于乳液的温度稳定性和液晶性 ,但助乳化剂量较低时经合理配方也能获得稳定的液晶乳液 ;其中含3 %高碳醇和 5 %甘油的乳液稳定性及液晶性均较好 ,5 %高碳醇和 3 %甘油的助乳化剂体系不宜采用更多还原

【Abstract】 Cosmetic emulsions containing liquid crystal were prepared by using the mixture of sucrose stearate and Span as a primary emulsifier(SSE) while C 16-18 fatty alcohol and glycerol as co-emulsifiers.The effects of dosage of co-emulsifier on the thermostability and liquid crystal status of the emulsions were investigated in terms of tertiaty phase diagram.It is showed that this mixing emulsifiers system results in stable cosmetic emulsions containing liquid crystal.Generally,thermostability and liquid crystal status of the emulsions benefits from larger dosage of co-emulsifier,and so does the less dosage if formula is reasonable.Emulsions containing 3 % C 16-18 fatty alcohol and 5 % glycerol possess good thermostability and liquid crystal status but those containing 5 % C 16-18 fatty alcohol and 3 % glycerol are inadvisable.更多还原
