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.
