The safty and degree for the extractable and leachable of polymer material used in storage and transportation of the process liquid in medical
pharmaceutical and food industry have attracted more and more attention by public. For extractalbe test
it is important to determine simulation solvent system based on actual liquid product ingredients. After explaining the principle of solvent selection and theory of solvent classification
the review propose the two solutions for selection simulation solvent in extractable experiment
based on the Induction and summary of reported article and literature. It can provide researchers with ideas and advice for design and evaluation simulation solvent system in extraction experiment in the future.
