Patent number: 6407274Abstract: The present invention relates to silicone based amine oxides. The silicone amine oxides are non-irritating, high foaming products that are substantive to substrates like fiber, metal hair and skin. They also possess good detergency. They are made by reaction of a suitable silicone compound containing an epoxide functionality, followed by reaction with hydrogen peroxide to make the amine oxide.Type: GrantFiled: December 26, 2001Date of Patent: June 18, 2002Assignee: Siltech CorporationInventors: Richard O. Vrckovnik, Mark Riddle

Patent number: 6265598Abstract: A hydrolyzable group end-blocked organopolysiloxane is prepared by reacting (A) an organopolysiloxane having a silanol group at each end of its molecular chain with (B) an organosilicon compound having hydrolyzable groups or a partial hydrolyzate thereof in the presence of (C) a condensation catalyst. Use is made of a vibratory mixer comprising a conduit through which a fluid flows in an axial direction and an agitating element disposed in the conduit for reciprocal motion in the flow direction. A reactant mixture of necessary components is introduced into the conduit where the components are vibro-agitated by the agitating element while reaction takes place.Type: GrantFiled: October 13, 2000Date of Patent: July 24, 2001Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Kenichi Kimura, Masatoshi Miyake, Nobuhiko Kodana
