摘要：
The present invention relates to a process for producing a W/O/W type multiple emulsion using a polyglycerol polyricinolate (i.e. a polyglycerol ester of a polycondensed fatty acid of castor oil).The use of the polyglycerol polyricinolate is effective in increasing the rate of formation of the W/O/W type multiple emulsion remarkably and giving a W/O/W type multiple emulsion which is stable over a long period of time. The W/O/W type multiple emulsion has also an excellent heat stability and is useful for the production of medicines and cosmetics.
