Abstract
A cross-linked composition comprises the reaction product of an organohydrogensiloxane and a cross-linker, in the presence of a hydrosilylation catalyst. The organohydrogensiloxane comprises siloxy units of average formula (I): (RSiO)(R—SiO)(RRSiO)(RHSiO)(RRSiO)(RRSiO)—(RSi—O). Each of Rand Ris an independently selected hydrogen atom or a substituted or unsubstituted hydrocarbyl group. Ris a hydrogen atom or a group having at least one carboxyl group or a precursor thereof. Ris an independently selected substituted or unsubstituted hydrocarbyl group. Further, a≥0, b≥0, c≥1, d≥0, and e≥1. The cross-linker has at least two aliphatic unsaturated hydrocarbon groups. A method of forming the cross-linked composition comprises the steps of providing the organohydrogensiloxane and cross-linker, and combining the organohydrogensiloxane and cross-linker in the presence of the hydrosilylation catalyst to form the cross-linked composition. A cosmetic composition is provided that includes the cross-linked composition and at least one cosmetic component.
