Patent number: 8110630Abstract: Gel compositions containing a silicone elastomer from the reaction of an organohydrogensiloxane having at least two SiH containing cyclosiloxane rings in its molecule, a compound having at least two aliphatic unsaturated hydrocarbon groups in its molecule, and a hydrosilylation catalyst. The silicone elastomer reaction product may itself be a gelled composition, or optionally may be contained in a carrier fluid to form a gel. The gel compositions may further contain a personal or healthcare active. The actives may be incorporated into the gel via either a pre or post load method.Type: GrantFiled: March 20, 2007Date of Patent: February 7, 2012Assignee: Dow Corning CorporationInventors: Shaow Lin, James McVie, Paul Vandort

Patent number: 5603888Abstract: A process of manufacturing elastomeric fibers in which fibers are obtained by co-extruding an extrudable and curable .tbd.SiO-- containing material and an aqueous organic polymer solution into a coagulation bath. The .tbd.SiO-- containing material is surrounded by the coagulated organic polymer. The .tbd.SiO-- containing material is then cured inside the protective sheath that is formed, and thereafter the organic polymer sheath is dissolved to expose a continuous elastomeric fiber of the .tbd.SiO-- material.Type: GrantFiled: July 13, 1995Date of Patent: February 18, 1997Assignee: Dow Corning CorporationInventors: John D. Blizzard, Steven E. Cray, Jenny L. Gilles, Daniel Graiver, Arnold W. Lomas, James McVie
