Abstract: Encapsulation compounds of butyl-methoxydibenzoylmethane (BMDBM) and octyl methoxycirmamate (OMC) were prepared separately by encapsulating with hydroxypropyl-β-cyclodextrin.Three encapsulation methods,including ultrasonic method,grinding method and solution stirring method were compared based on encapsulation ratio results.The preparation technology of encapsulation compounds was improved with orthogonal test.Results show that,solution stirring method is the most suitable method to prepare the encapsulation compounds.The encapsulation ratio of BMDBM and OMC in encapsulation compounds can be optimized by orthogonal test,and improved to 63.06%±2.5% and 56.43%±2.0% respectively.Encapsulation compounds can be applied in sun-screening cream,and display good photo-stability.

Key words: chemical sun-screening agent, hydroxypropyl-β-cyclodextrin, encapsulation technology
