Abstract
This invention relates to a foam control composition comprising: (A) a silicone antifoam comprising (i) an organopolysiloxane having at least one silicon-bonded substituent of the formula X—Ar, wherein X represents a divalent aliphatic group bonded to silicon through a carbon atom and Ar represents an aromatic group, (ii) an organosilicon resin having the formula RSiOwhere Rrepresents a hydrocarbon, a hydrocarbonoxy or a hydroxyl group and a has an average value of 0.5 to 2.4, and (iii) a hydrophobic filler; and (B) an organopolysiloxane resin having at least one polyoxyalkylene group in which the organopolysiloxane resin comprises tetrafunctional siloxane units having the formula SiOand monofunctional siloxane units having the formula RSiO, wherein the total number of tetrafunctional siloxane units in the resin is at least 50% based on the total number of siloxane units, and Rrepresents a hydrocarbon group. The foam control composition may be added to a potentially foaming liquid, particularly a detergent, such as an HDL detergent.
