摘要：
A process is provided for producing a water-oil-water type multiple emulsion comprising:a. adding an emulsifying amount of polyglycerol polyricinoleate to an oil phase;b. forming an oil in water emulsion by adding the product of step a to an aqueous phase;c. inverting the oil in water emulsion of step b into a water in oil emulsion by agitating; andd. forming a water-oil-water emulsion by adding the water in oil emulsion of step c to an outer aqueous phase.The emulsions produced by this process are useful for preparing medicines and cosmetics.
