The compositions of the present invention consist essentially of (I) a reaction product, (II) a nonaqueous liquid continuous phase, and (III) a moderately hydrophobic particulate stabilizing aid. Component (I) is prepared by heating a mixture of (i) a polyorganosiloxane fluid, (ii) a silicon compound, (iii) a finely divided filler and (iv) a catalytic amount of a compound for promoting the reaction of components (i) to (iii) at a temperature of 50.degree. C. to 300.degree. C. The compositions of the present invention can additionally contain (IV) at least one nonionic silicone surfactant, and (V) a nonreinforcing inorganic filler.

Stable dispersible silicone compositions

Disclosed are aqueous liquid detergent compositions comprising dispersed particles of a silicone-based suds suppressor system and a separately added moderately hydrophobic particulate silica stabilizing agent. Such a separately added stabilizing agent serves to retard coalescence and coagulation of the suds suppressor particles and thus enhances the storage stability of the suds suppressor-containing detergent compositions of this invention.

Stable liquid detergent compositions comprising a dispersible

A suds-controlling composition of improved stability in aqueous surfactants, such as detergents, is disclosed comprising a silicon antifoam consisting essentially of a liquid branched polyorganosiloxane and a finely divided filler having a hydrophobic surface; a polyorganosiloxane polyoxyalkylene copolymer; and a cyclic organopolysiloxane. The silicone antifoam and polyorganosiloxane polyoxyalkylene copolymer are combined in a ratio of 1/3 to 3/1.

Suds-controlling composition for aqueous compositions

A suds-controlling composition which comprises 100 parts by weight of a silicone antifoam which has a liquid branched polyhydrocarbyl siloxane material having at most 2 mole % branching and at least 2 trifunctional or tetrafunctional siloxane units, a finely divided hydrophobic filler, and from 75 to 900 parts by weight of a polyorganosiloxane polyoxyalkylene copolymer can be used as a stable suds-controlling composition for aqueous surfactant compositions, especially liquid detergents.
