20110039753 | Fabric Care Emulsion - The invention relates to oil-in-water emulsions, methods of making said emulsions and their uses in fabric care or hair care compositions. The fabric care composition comprises a silicone oil-in-water emulsion which emulsion is obtained by a. forming an oil phase by mixing at least one silicone compound with at least one silicone-free oil, b. optionally adding an emulsifier, c. adding water, d. forming an oil-in-water emulsion. A silicone oil, comprising a siloxane or polysiloxane compound, for example polydimethyl siloxane (polydimethyl silicone or PDMS), or a derivative thereof, e.g., amino and amido silicone, diluted with a silicone-free oil still can provide an emulsion providing high fabric care properties while decreasing the costs. | 02-17-2011 |
20110313060 | Silicone Dispersions - A non-aqueous silicone emulsion is provided. It comprises a continuous phase of a polar organic liquid containing droplets of an organopolysiloxane dispersed therein. An organic wax, which has a melting point in the range 40 to 100° C. and is sparingly soluble in the polar organic liquid at 25° C., is dispersed in the polar organic liquid continuous phase as a network of interconnected particles which stabilises the organopolysiloxane droplets in emulsion in the polar organic liquid. A process for the production of the emulsion is also disclosed. | 12-22-2011 |
20140093547 | Emulsion Polymerisation Method - The invention relates to a method for the production of silicone in water emulsions by emulsion polymerisation. The emulsion contains particles of an organopolysiloxane polymer having an average particle diameter of less than 1 μm. The method comprises: —combining a silanol end-blocked organosiloxane starting polymer, water, and a surfactant; said starting polymer having a viscosity of at least 2 Pa·s preferably at least 2.5 Pa·s preferably at least 3.5 Pa·s preferably at least 4 Pa·s and up to 150 Pa·s; —emulsifying the starting polymer by agitating or shearing the ingredients; —polymerizing the starting polymer to form a longer chain silanol end-blocked organopolysiloxane polymer; wherein at least a portion of said polymerising step is performed at a temperature of less than or equal to 16° C. preferably less than or equal to 15° C. | 04-03-2014 |
