- 1. A composition suitable for use in cosmetics consisting essentially of an oil-in-water dispersion wherein the external water phase of said dispersion contains an oil dispersed therein, said oil-in-water dispersion being stabilized by spheres dispersed in said external water phase without causing destruction of said spheres, said spheres consisting essentially of organized molecular layers of a nonionic amphiphilic lipid material encapsulating an internal aqueous phase, said nonionic amphiphilic material being selected from the group consisting of
- (i) a straight or branched chain polyglycerol ether having the following formulae: ##STR19## wherein n has a statistical average value from 2 to 6 and R represents a straight or branched chain saturated aliphatic group containing from 16 to 20 carbon atoms or a hydrocarbon group of a lanolin alcohol, and
- (ii) a polyoxyethylenated sterol;
- said nonionic amphiphilic lipid material being present in an amount from 2 to 10 weight percent based on the total weight of said composition,
- said oil dispersed in said external water phase being selected from the group consisting of (a) a liquid triglyceride and (b) a fatty acid ester of a branched alcohol and having the formula R--COOR' wherein R represents the radical of a fatty acid containing 8 to 20 carbon atoms and R' represents a branched hydrocarbon chain containing 3 to 20 carbon atoms, said oil being present in an amount ranging from 2 to 40 weight percent of said composition, the weight ratio of said lipid material to said oil ranging from 0.2:1 to 1:1.
