  • Elastomer gels containing volatile, low molecular weight silicones
    Patent number: 5760116
    Abstract: A composition comprising the hydrosilylation addition product of a linear alkenyl functionalized polyorganosiloxane and an M.sup.H Q resin and a low molecular weight silicone when subjected to shearing provides for components in personal care formulations that have improved spreadability and substance.
    Type: Grant
    Filed: September 5, 1996
    Date of Patent: June 2, 1998
    Assignee: General Electric Company
    Inventors: John A. Kilgour, Virginia Van Valkenburgh Powell
  • Surfactant compositions
    Patent number: 5360571
    Abstract: Synergistic surfactant compositions. Polysiloxane-polyoxyalkylene copolymers in which the polyether pendants bear carboxylic acid groups or salts of carboxylic acid groups are demonstrated to have synergystic interactions with anionic and cationic organic surfactants to improve the surface characteristics of a solution, requiring unexpectedly low concentrations to obtain specific surface tension values or to attain critical micelle concentrations in aqueous solutions. Compositions containing an organic surfactant and a polysiloxane-polyoxyalkylene copolymer bearing carboxyl groups are claimed. A method for modifying the surface properties of an aqueous system by employing such compositions as components of the system is also claimed.

  • Silicone surfactants having t-butyl terminated polyether pendants for use in high resilience polyurethane foam
    Patent number: 5198474
    Abstract: Siloxane-polyether copolymer surfactants for manufacture of high resiliency polyurethane foam which are capped with t-butyl groups on the ends of the polyether blocks, polyurethane foam compositions containing such surfactants, a method for making polyurethane foam using such surfactants, and polyurethane foam made the method are disclosed and claimed. The t-butyl-capped surfactants afford improved surfactant potencies and foam breathabilities relative to the commonly-employed methyl-capped surfactants.
