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 |

20110028635 | Silicone Polymer Dispersion And Method Of Forming Same - A dispersion includes dispersed particles. The particles include a reaction product of a first polymer, a second polymer, and a chain terminator. The first and second polymers have at least two Si—H moieties and silicon bonded unsaturated moieties, respectively. The chain terminator has one Si—H moiety or one unsaturated hydrocarbon moiety.
