摘要：
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): (R 3SiOi/2)(R 2- Si0 2 2) (R1R Si0 2/2)b(R HSi0 2/2) c(R R Si0 2/2) d(R R Si0 2/2 ) -(R 3Si-Oi /2) . Each of R1 and R2 is an independently selected hydrogen atom or a substituted or unsubstituted hydrocarbyl group. R3 is a hydrogen atom or a group having at least one carboxyl group or a precursor thereof. R4 is 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 or ganohydrogensiloxane and cross-linker, and combining the or ganohydrogensiloxane 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.
