摘要： A composition is provided that includes an elastomer and an additive. The additive stabilizes the elastomer, although it may be useful for an alternate or additional purpose. The elastomer can have a moiety according to the general formula: A-B-A or B-A-B. Each A independently comprises a polysiloxane moiety having at least two siloxy (Si—O) groups. Each B independently comprises a moiety, or a precursor thereof, having at least one carboxyl group. B is bonded to a silicon atom in A. The elastomer may comprise the reaction product of a reaction of: a first component having at least one reactive group; a second component having at least one reactive group; and a third component having at least two reactive groups reactive with the reactive groups of the first and second components. In addition, a cosmetic composition is provided that includes the elastomer, the additive, and at least one cosmetic component.

摘要： A composition comprises (A) a silicone elastomer. The (A) silicone elastomer comprises the reaction product of: (a) an organohydrogensiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule; (b) a crosslinking agent having an average of at least two ethylenically unsaturated groups per molecule; and (c) a hydrosilylation catalyst. The reaction product is formed in the in the presence of (d) a silicone polyether polymer; and (e) particles. The composition further comprises (B) a carrier fluid. The (e) particles are dispersed in the (A) silicone elastomer in the composition. A method of preparing the composition is also disclosed.
