Patent number: 8697828Abstract: The present invention relates to a liquid hydrosilicone resin and a preparation process thereof. The average composition of the liquid hydrosilicone resin is represented by the following formula: (R1R2R3SiO1/2)M.(R4R5SiO2/2)D. (R6SiO3/2)T.(SiO4/2)Q wherein R1 to R6 are identical or different radicals independently selected from the group consisting of organic groups and a hydrogen atom, with the proviso that at least one of R1to R6 is a hydrogen atom bonded directly to a silicon atom. The liquid hydrosilicone resin is obtained by dispersing a hydrosilicone oil, a hydroxyl silicone resin and a dehydrogenation catalyst in a solvent to form a dispersion, allowing the dispersion to react, and then removing the solvent and the catalyst.Type: GrantFiled: March 14, 2013Date of Patent: April 15, 2014Assignee: Henkel AG & Co.

Patent number: 8686174Abstract: The present invention provides a novel modified-polysiloxane, method for producing the same, and a cosmetic containing the same. The aforementioned modified-polysiloxane exhibits a reduced viscosity and superior operationability as compared with conventional polyoxyalkylene-modified polysiloxanes and polyglycerol-modified polysiloxanes. In addition, since the modified-polysiloxane is hardly oxidized in air, hardly produce allergenic compounds such as formates, and aldehydes such as formaldehyde, during storage over time, an increased environmental compatibility can be exhibited. In addition, the modified-polysiloxane of the present invention exhibits a reduced hydrolysis property and is stable. In the modified-polysiloxane of the present invention, the terminal hydroxyl groups of a polyglycerol-modified polysiloxane are partially blocked with hydrocarbon groups.Type: GrantFiled: December 21, 2009Date of Patent: April 1, 2014Assignee: Dow Corning Toray Co.

Patent number: 8680225Abstract: The present invention is directed toward a series of polyglycerol polyesters that have silicone terminal groups with tunable ascetics and performance in cosmetic formulation. These novel silicone containing polyglycerol polyesters are designed to be multidimensional. Multidimensional is meant that the polymer contains a variety of groups containing different chemical and physical properties covalently bonded together. The physical properties of the current invention can be tuned rapidly by controlling the ratio of fatty groups, as well as the cross-linker used. Tuned here is meant the ability to adjust the physical properties to a desired value. The resulting polyglycerol polyesters have outstanding aesthetics and physical properties.Type: GrantFiled: March 25, 2013Date of Patent: March 25, 2014Assignee: Surfatech CorporationInventor: Thomas George O'Lenick
