  • Patent number: 10918587
    Abstract: 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.

  • Publication number: 20200262980
    Abstract: An elastomer has the general structure of: where: subscript a is 50-500, b is 1-10, c is 2-30, R1 has the structure: —CH2(CH2)nO(CH2)pCH(OH)(CH2)qNR2R2? where n, p and q are each independently 1-5 and R2 and R2? are independently selected from alkyl and hydroxyalkyl groups having 1-5 carbon atoms; where X is a crosslinker remnant bound to a siloxane unit corresponding to subscript c of a siloxane backbone polymer in addition to the one shown so that the crosslinker remnant in each occurrence is a reaction product with two siloxane backbone polymers, wherein the crosslinker is selected from a group consisting of primary organic dienes, divinyl siloxane and polyoxyalkylenes wherein at least two X components correspond to crosslinker remnants connecting the same two siloxane backbone polymers

  • Patent number: 9822221
    Abstract: A cross-linked composition comprises the reaction product of a first reactant having at least one hydroxyl or amine (functional) group, a second reactant having at least one hydroxyl or amine (functional) group, and a siloxane having at least two terminal anhydride groups reactive with the functional groups of the first and second reactants. The first reactant is selected from the group of first siloxanes having at least one hydroxyl or amine group, a first organic alcohol having at least one hydroxyl group, a first organic amine having at least one amine group, or combinations thereof. The second reactant is selected from the group of second siloxanes having at least one hydroxyl or amine group, a second organic alcohol having at least one hydroxyl group, a second organic amine having at least one amine group, or combinations thereof. If utilized, the first siloxanes and/or second siloxanes are different from the siloxane.
