  • HYDROLYSIS RESISTANT ORGANOMODIFIED TRISILOXANE SURFACTANTS
    Publication number: 20120100119
    Abstract: Three types of trisiloxane surfactants having the basic formula: MDM? are described wherein the substituents on the differing M and M? groups, in conjunction with pendant polyalkylene oxide substituents on the D group render the surfactant resistant to hydrolysis under either basic or acidic conditions outside the pH range of 6.0 to 7.5. The compositions are useful in agricultural, household and cosmetic applications.
    Type: Application
    Filed: December 8, 2011
    Publication date: April 26, 2012
    Applicant: Momentive Performance Materials Inc.
    Inventors: George A. Policello, Mark D. Leatherman, Wenqing Peng, Suresh K. Rajaraman, Sophia Xia
