  • Amphiphilic organopolysiloxane dendrimers with high refractive index
    Patent number: 9051434
    Abstract: Branched organopolysiloxanes of low molecular weight contain bonded arylalkyl groups. Si—C bonded surfactant groups, preferably polyoxyalkylene polyether groups, and long chain alkyl groups, exhibit a high refractive index, are completely or partially self-emulsifying, and are compatible with a variety of cosmetically acceptable oils and solvents.
    Type: Grant
    Filed: January 31, 2013
    Date of Patent: June 9, 2015
    Assignee: Wacker Chemical Corporation
    Inventors: Aroop K. Roy, Amitabha Mitra, Michael L. Coffey

  • Paste Composition For Use In Coating Films, Fibers, And Fabrics And Method of Manufacture
    Publication number: 20120114578
    Abstract: A paste composition for use in coating film, fiber, or fabric includes a dry grease having a discontinuous aqueous phase having a non-ionic alkoxylate surfactant portion and a polyorganosiloxane oil phase. The past further includes a dry-grease suspended powder. The surfactant portion is effective to suspend the powder forming a self-supporting form.

  • Asphalt release agents and use thereof
    Patent number: 6143812
    Abstract: Asphalt release coatings are prepared by applying an aqueous emulsion containing an organopolysiloxane component, an effective amount of one or more emulsifying surfactants, and most minor amount of a multiple release additive. The compositions exhibit improved release, particularly multiple releases, even with polymer modified asphalt binders.
