Patent ID: 7632890

Claim:
A granulated foam control composition comprising: (i) a foam control agent comprising: 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, a hydrophobic filler dispersed in the polydiorganosiloxane fluid; and optionally an organosilicon resin; and (ii) an additive composition of melting point 35 to 100° C. comprising: (A) a polyol ester selected from glycerol triesters, esters of pentaerythritol, or a mixture of polyol esters containing carboxylate groups of different chain length each having 7 to 36 carbon atoms, wherein at least 90% of the hydroxyl groups of the glycerol triesters are esterified, and wherein at least 70% of the hydroxyl groups of the esters of pentaerythritol are esterified; and optionally 5 to just less than 50% by weight of a component (B) selected from fatty alcohols containing 8 to 32 carbon atoms, fatty acids having 8 to 36 carbon atoms, or mixtures of monoesters and diesters of glycerol which are miscible with the polyol ester (A) and contains groups more polar than the carboxylate ester groups of the polyol ester (A) wherein the foam control agent (i) and the additive composition (ii) are supported on a particulate carrier with the proviso that a mixture of (i) and (ii) is deposited onto the particulate carrier in non-aqueous liquid form.
