Objective:The purpose of the present study was to investigate the fessibility that the essential oilas the oil phase of the microemulsion and optimize the formula of Chuan zhi microemulsion.Method:The pseudoternary phase diagrams were developed for various microemulsion formulations.The microemulsion was optimized using a three-factor
three-level Box-Behnken design.The independent variables selected were surfactant
co-surfactant and oil;dependent variables(responses) were polydispersity index(PDI).Mathematical equations and response surface plots were used to relate the dependent and independent variables.Optimized formulation factors were selected by feasibility and grid search.Result:Validation test showed that the average particle size of antalgic microemulsion was(13.17 ± 0.07) nm.Conclusion:The essential oil can be the oil phase of the microemulsion.The Box-Behnken design can optimize the formulation objectively.
