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