  • Silicone elastomer gels incorporating natural oils
    Patent number: 11414522
    Abstract: Organopolysiloxane gels containing a hydrocarbon diluent and non-chemically bonded natural oils are prepared by the hydrosilylative gelling of a mixture of an aliphatically unsaturated organopolysiloxane, an Si—H-functional organopolysiloxane, and a long chain ?-olefin, in the presence of a hydrocarbon diluent and at least one natural oil. Stable creamy gels are produced by shearing the gel product, and contain only a minor amount of crosslinked organopolysiloxane elastomeric component.
    Type: Grant
    Filed: November 20, 2017
    Date of Patent: August 16, 2022
    Assignee: Wacker Chemie AG
    Inventors: Amitabha Mitra, Chelsea Grimm, Margaret Whitton
  • HYDROPHILIC CYCLODEXTRIN-CONTAINING SILICONE GELS
    Publication number: 20220089873
    Abstract: Solvent-swollen crosslinked silicone gels containing covalently bonded cyclodextrin groups are prepared by hydrosilylation. The swollen gels are storage stable, compatible with water and polar solvents, and display a significant water break effect.

  • Silicone defoamer compositions
    Patent number: 9815003
    Abstract: Defoamer compositions contain a) a two-stage hydrosilylation product of one or more M4HQ or M3HTphenyl starting materials with a hydrosilylatable composition containing ?-methylstyrene, and then with a linear or branched organopolysiloxane bearing at least two hydrosilylatable groups; b) a silicone resin; and c) silica. The defoamers are particularly useful in machine laundering and dishwashing compositions.
