Abstract: An anti-foaming agent containing (A) an organopolysiloxane and a finely powdered inorganic filler, (B) a polyoxyalkylene group-containing branched chain organopolysiloxane, and (C) an anionic surfactant. This anti-foaming agent exhibits stable anti-foaming performance even at high temperatures that reach, for example, 80QC or under strongly alkaline conditions and produces no aggregates.

Abstract: In a process for separating a solid material from a suspension of the solid material in water, an organopolysiloxane polyalkylene oxide copolymer comprising a branched organopolysiloxane structure is added to the suspension of solid material in water and the suspension is drained. The organopolysiloxane polyalkylene oxide copolymer comprising a branched organopolysiloxane structure increases the rate of drainage of the suspension.

Abstract: A disiloxane having a particular structure is disclosed. A method of preparing the disiloxane is also disclosed. The disiloxane is suitable for numerous end use applications. For example, the disiloxane may be utilized as a wetting agent and/or surfactant. A hydrophobing agent obtainable as a product of the hydrolysis of the disiloxane is also disclosed. The disiloxane may alternatively be utilized in a pesticidal and/or herbicidal composition, a coating, a household care composition, a personal care composition, an emulsion, or an additive for dry mixes.

Abstract: A granulated product comprises a liquid organosilicon compound supported on a particulate carrier which is agglomerated into granules by a binder. A process for the production of a granulated product comprises depositing an organosilicon compound and a binder in a liquid state on a particulate carrier and subjecting the carrier thus treated to conditions in which the binder is solidified, thereby agglomerating carrier particles into granules. The particulate carrier is anhydrous sodium sulfate of mean particle size 1 to 40 ?m.

Abstract: A process for making a foam control composition comprising a cross-linked polyorganosiloxane in which is dispersed a filler, with hydrophobic surface, comprising step (A) mixing (i) a finely divided filler, (ii) a polyorganosiloxane having on at least two reactive substituents, for example on average two reactive substituents, and (iii) a polyorganosiloxane having at least three reactive substituents, capable of addition reaction via hydrosilylation; (B) hydrosilylation reaction of components (ii) and (iii) until the mixture at least partially gels, followed by applying shearing forces to this at least partially gelled mixture. Optionally step (A) comprises a diluent or solvent and after step (B) an emulsification step is carried out to make the foam control composition into an O/W emulsion.

Abstract: A method of making silicone-based foam control agents comprising: i) preparing a polysiloxane containing polymer by the polymerisation of siloxane containing monomers and/or oligomers in the presence of an inert organopolysiloxane and/or an organic fluid, a suitable catalyst and optionally an end-blocking agent; ii) where required quenching the polymerisation process; wherein the inert organopolysiloxane and/or organic fluid is substantially retained within the resulting diluted polysiloxane containing polymer; iii) introducing from 0.1 to 10% by weight of a suitable filler prior to during or subsequent to step (i); iv) optionally introducing up to 5% by weight of a suitable silicone resin during or subsequent to step (i) and v) where required, adapting the foam control agent produced in steps (i) to (iv) into a suitable form of delivery therefor.

Abstract: A foam control composition comprises a polydiorganosiloxane fluid comprising units of the formula where each group R, which may be the same or different, is selected from an alkyl group having 1 to 36 carbon atoms or an aryl group or aralkyl group having up to 36 carbon atoms, the mean number of carbon atoms in the groups R being at least 1.3, and an additive composition of melting point 35 to 100° C. comprising a substantially non-polar organic material, preferably a polyol substantially fully esterified by carboxylate groups each having 7 to 36 carbon atoms.

Abstract: Foam control compositions herein can be used in aqueous compositions that are liable to foam. The foam control compositions is added to detergent compositions, particularly detergent powders, to inhibit excessive foaming when the detergent is used in washing. In particular, the foam control composition contains a non-silicon-containing organic liquid, a branched siloxane resin, a particulate filler which is insoluble in the organic liquid, and an additive composition of melting point 35 to 100° C. that is substantially non-polar organic material which is miscible with the organic liquid.

Abstract: A foam control composition contains a liquid polymer of an unsaturated hydrocarbon, a branched siloxane resin, and a particulate filler which is insoluble in the liquid hydrocarbon polymer. The foam control composition can additionally contain a polysiloxane fluid.
