Abstract:
1. A granulated foam control composition comprising (A) a foam control agent comprising where each group R is independently the same or different and is selected from the group of an alkyl group having from 1 to 36 carbon atoms, an aryl group, and an aralkyl group having up to 36 carbon atoms, wherein the mean number of carbon atoms in the groups R is at least 1.3; (B) an organic additive having a melting point of from 45° C. to 100° C. and comprising a polyol ester which is a polyol fully or partially esterified by carboxylate groups each having from 7 to 36 carbon atoms and which is miscible with the polydiorganosiloxane fluid (A)(i); (C) a water-soluble particulate inorganic carrier; and (D) a polymer having a net cationic charge with a net charge density of from about 0.05 to about 12 meq/g and a molecular weight of from about 80,000 to about 4,000,000, wherein said polymer having a net cationic charge has a cationicity parameter of greater than 50 dalton meq/g.
