title: [Study on the solubilization of O/W microemulsion for volatile oil].
abstract: OBJECTIVE
  To study the solubilization of O/W microemulsion system for volatile oil.
  
  
  METHODS
  Pseudo-ternary phase diagrams were prepared by using the method of titration, then investigating the solubilization of microemulsion system for different kind of volatile oil was investigated with the diagrams, and the effect of the formulation of microemulsion on the solubilization of Citrus sinensis oil were studied.
  
  
  RESULTS
  Kinds of volatile oil have an accelerated solubility in the microemulsion system. The species and dosage of oil phase and surfactant could influence the solubilization of microemulsion on Citrus sinensis oil.
  
  
  CONCLUSIONS
  It is recommended to select a new method to solve the stabilization of volatile oil in the liquid preparation by the solubilization of suitable formulation of microemulsion.
