Assignee: L'Oréal

This invention relates to an o/w emulsion comprising: a) at least one continuous aqueous phase; b) at least one oily phase dispersed in the aqueous phase; c) at least one mixture of surfactants; and d) one or more UV-screening agents.

Said surfactant mixture includes: i) one or more fatty acid esters of a polyalkylene glycol; ii) one or more fatty acid esters of glycerol; iii) one or more fatty acids in free form; and iv) one or more alkali metal salts of an ester of phosphoric acid and of a fatty alcohol. 

According to the inventors, this composition meets the need for o/w emulsions that are stable and fluid while at the same time capable of efficiently screening out UV radiation. The described composition reportedly obtains a very high sun protection factor (SPF) while also being stable and extremely fluid.
