Patent number: 10918587Abstract: 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.Type: GrantFiled: March 8, 2018Date of Patent: February 16, 2021Assignee: Dow Silicones CorporationInventors: Mary Kay Crofoot, Kimmai Thi Nguyen, Kenneth E.
