A polymer/hydrophobic ester oil blend is provided comprising (a) a cosmetically acceptable hydrophobic ester oil; and (b) a thickening polymer powder, thickening polymer, wherein the thickening polymer is a silylated cellulose polymer, comprising a cellulose polymer functionalized with —Si(R)groups; wherein each Ris independently selected from the group consisting of a hydrogen, a Calkyl group, a Chaloalkyl group, an aryl group, a Calkylaryl group and a Chaloalkylaryl group; and wherein the cellulose polymer has a weight average molecular weight of 50,000 to 1,500,000 Daltons. Also provided are suncare formulations containing same and methods of using same.

Polymer/hydrophobic ester oil blend

A curable composition is disclosed. The curable composition comprises (I) an epoxide-functional silicone-acrylate polymer and (II) an aminosiloxane. The epoxide-functional silicone-acrylate polymer comprises acrylate-derived monomeric units comprising siloxane moieties, epoxide-functional moieties, and optionally, hydrocarbyl moieties, and the aminosiloxane comprises an average of at least two amine functional groups per molecule. A method of preparing the curable composition is also disclosed, and includes reacting (A) an acryloxy-functional organosilicon component, (B) an epoxy-functional acrylate component, and optionally (C) an acrylate component, to give the epoxide-functional silicone-acrylate polymer (I), and combining the epoxide-functional silicone-acrylate polymer (I) with the aminosiloxane (II). An aminosiloxane-silicone-acrylate copolymer prepared with the composition, a cured product comprising the same, and methods of preparing the same, are also disclosed.
