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: Formulation comprising hydrophobicized particles of silicon dioxide, mineral oil and one or more emulsifiers, where the hydrophobicized silicon dioxide is a fumed silicon dioxide, possesses a BET surface area of 200 to 300 m2/g, has on the surface of the particles O—Si—(CnH2n+1)3 groups, where n is 1 to 3 and where the (CnH2n+1) units are alike or different, has a carbon content of 1.5% to 5% by weight, based on the hydrophobic silicon dioxide, and is present in the formulation with a fraction of 0.05% to 5% by weight.

Abstract: Aqueous concentrates and aqueous compositions (e.g., agrochemical) containing a water-insoluble liquid antifoam agent (e.g., liquid silicone-containing antifoam agent) are disclosed. The water-insoluble liquid antifoam agent is incorporated into the concentrate or composition as a solution of the water-insoluble liquid antifoam agent solubilized in an organic solvent (e.g., isopropyl myristate, butyl cocoate or butyl laurate).
