METHODS : Using central composite design-response surface methodology ,the formula of Arbutin cream was optimized using the spreadability of cream as index and with the amounts of cetyl alcohol ,sodium lauryl sulfate-triethanolamine (2∶1)and dimethicone as indepen- dent variables. The appearance characteristic ,article size ,pH value ,spreadability ,stability of preparation and the content of arbutin were studied. RESULTS :The optimal conditions were cetyl alcohol 60 g ,sodium lauryl sulfate-triethanolamine (2∶1)10g ,and di- methicone 25g. According to the optimal conditions ,the diameter of spreadability of prepared cream was about 58.7mm ,and cream suited with the property of semi-fluid cream. The pH value of cream ranged w
