Abstract
What is provided herein are skin care compositions containing discrete microdroplets of an oil in water stabilized by in situ polymerization of a water-soluble vinyl monomer. The discrete microdroplets are prepared by dispersing the oil, preferably a silicone, in water, adding the water-soluble vinyl monomer, preferably vinylpyrrolidone, and polymerizing the monomer in situ such that the oil is stabilized in the resulting polymer solution as discrete microdroplets.
