Granulated foam control composition comprising a polyol ester and cationic polymer

A method of reducing foam during a rinsing step comprising

• providing a granulated foam control composition comprising
• (A) a foam control agent comprising
• (i) a polydiorganosiloxane fluid comprising units of the formula
• 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;
• (ii) a hydrophobic filler dispersed in the polydiorganosiloxane fluid;
• and
• (vi) optionally an organosilicon resin;
• (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;
• (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 from about 50 to about 1500 dalton meq/g;
• and
• incorporating the granulated foam control composition into a laundry detergent powder.

A method of manufacturing a granulated foam control composition comprising:

• mixing
• (A) a foam control agent comprising
• (i) a polydiorganosiloxane fluid comprising units of the formula
• 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;
• (ii) a hydrophobic filler dispersed in the polydiorganosiloxane fluid;
• and
• (iii) optionally an organosilicon resin;
• and
• (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
• depositing the mixture of (A) and (B) on a water-soluble particulate inorganic carrier, the mixture of (A) and (B) being in non-aqueous liquid form prior to depositing said mixture on the water-soluble particulate inorganic carrier;
• and
• depositing (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 from about 50 to about 1500 dalton meq/g, on the water-soluble particulate inorganic carrier in conjunction with the mixture of (A) and (B) being deposited on the water-soluble particulate inorganic carrier or after the mixture of (A) and (B) is deposited on the water-soluble particulate inorganic carrier.
