Abstract: A silicone-vinylester copolymer and methods for its preparation and use are provided. The silicone-vinylester copolymer can be made using a vinylester-functional siloxane macromonomer, which can be prepared by a process comprising hydroformylation of an alkenyl-functional polyorganosiloxane to form an aldehyde-functional polyorganosiloxane; oxidation of the aldehyde-functional polyorganosiloxane to form a carboxy-functional polyorganosiloxane, and transvinylation of the carboxy-functional polyorganosiloxane to form the vinylester-functional siloxane macromonomer. The silicone-vinylester copolymer is useful in personal care compositions.
