Abstract
The present invention relates to an oil-in-water emulsion composition, including: an oily phase dispersed in an aqueous phase; wherein the oily phase includes at least one crosslinked solid organopolysiloxane elastomer having at least one oxyalkylene group; and wherein the aqueous phase includes at least one polymer which is soluble or swellable in water. The present invention also relates to a cosmetic composition containing the above-noted composition, and methods of using. The present invention makes it possible to prepare oil-in-water emulsions which are stable even though they may not contain a conventionally used surfactant, this stability persisting even when the level of oily phase is high. Furthermore, the present invention provides compositions that are advantageously fresh and comfortable during application to the skin, which effects are otherwise not obtained with conventional compositions.
