Optimization of Preparation Technique of Guiji Cream by Orthogonal Test

Objective ： To select the best preparation technique of guiji cream. Method ：Oil phase, aqueous phase, the temperature of emulsification and stirring speed of emulsification were used as factors, and the stability of this preparation with content of ferulic acid were used as evaluation index. The best preparation technique of guiji cream was selected throug comprehensive analysis of a multi-indicator approach by orthogonal test. Result： The optimal composition of matrix and technology were as follows ：jojoba oil 20 g, emulsified silicone oil 40 g, glycerol 14 g, 12 alkyl sodium sulfate 0. 5 g, the temperature of emulsification was 90℃, and stirring speed was 150 r·min^-1. Conclusion： This preparation process is stable and feasible.
