Abstract: A cosmetic composition in the form of a creamy emulsion having an internal water phase in an oil phase includes at least one polyglyceryl ester, a glutamic acid, or a derivative thereof, at least one cosmetically acceptable glycol or diol, at least one oil, water, and optionally one or more additives. The composition excludes mineral and organic UV filters. The creamy emulsion demonstrates breaking and release of the water phase upon rubbing application of the composition on a substrate. The composition demonstrates stability at temperatures in a range from about 5° C. to about 45° C. for a period of eight weeks and under freeze-thaw conditions that range from about −20° C. to about 25° C., where the stability is evidenced by lack of separation of the water and oil phases and/or maintaining rheological characteristics over time in the absence of rubbing on a substrate.
