Abstract: The invention relates to branched organopolysiloxanes and emulsions thereof, and to methods of preparation and uses of the branched organopolysiloxanes and emulsions thereof. A branched organopolysiloxane is prepared by the reaction of a branching agent with a substantially linear organopolysiloxane containing at least one hydroxyl or hydrolysable group bonded to silicon, in the presence of an inert fluid and a catalyst, such as a phosphazene catalyst. Phosphazene catalysts also have the advantage that the content of undesired low molecular weight cyclic silicones in the polymerisation product is low.

Abstract: A process for preparing silicate shell microcapsules comprises adding a water reactive silicon compound to an oil in water emulsion, thereby condensing and polymerizing the water reactive silicon compound to form silicate shell microcapsules having a core comprising the oil phase of the said emulsion. The water reactive silicon compound comprises a tetraalkoxysilane and an alkoxysilane having an amino or quaternary ammonium substituted alkyl group.

Abstract: The present invention relates to a controlled release carrier system that can be incorporated into rinse-off application products containing at least one surfactant such as heavy duty liquids (HDL), Rinse Cycle Fabric Softeners (RCFS), Shampoos, Hair Conditioners, Shower Gels, cleansing products, and that enhance deposition of lipophilic active materials like fragrance, fine perfumes, flavors and other volatile compounds onto a surface. The fragrance composition is encapsulated within a shell comprising a silicon-containing material and the shell has a mean diameter size which is lower than 30 micrometer. The surfactant composition containing the fragrance composition is washed off and the fragrance is progressively released.

Abstract: This invention relates to organopolysiloxane (silicone) compositions containing an active material chosen to have a desired effect in the composition, such as a perfume, sunscreen, vitamin, drug, biocide, pest repellent, catalyst or cooling agent. The active material is generally an organic material which is not silicon-containing. In particular the invention relates to such composition in which the release of the active material from the composition is inhibited or controlled. The active material is incorporated in a blend of a wax with an organopolysiloxane which has been formed by polymerization in the presence of the wax. It was found that by polymerizing an organopolysiloxane in admixture with molten wax, a stable wax silicone dispersion is obtained which allows ready incorporation of an active material such as a perfume and which releases the perfume only slowly, and may be controlled to release the perfume or other active material in desired circumstances.

Abstract: Compositions containing suspended silicate shell microcapsules of a silicone textile treatment are disclosed. These compositions are particularly useful as textile treatments to impart hydrophobicity, softness, and flame retardant properties.

Abstract: The present invention relates to home and personal care compositions comprising a silicone oil-in-water emulsion stabilized by a protein or peptide and at least one home and/or personal care ingredient. Such compositions tend to provide desirable characteristics for the care and conditioning of hair, skin and fabric.
