Claims10
A foam control composition comprising a liquid polyisobutene having a molecular weight in the range 200 to 1500, a branched siloxane resin, a particulate filler which is insoluble in the liquid polyisobutene, and an organic polyol ester which is a polyol substantially fully esterified by carboxylate groups each having 7 to 36 carbon atoms.
A granulated foam control agent according to claim 18 characterized in that a water-soluble or water-dispersible binder is also deposited on the carrier particles.
