Abstract
A suds-controlling composition which comprises 100 parts by weight of a silicone antifoam which has a liquid branched polyhydrocarbyl siloxane material having at most 2 mole % branching and at least 2 trifunctional or tetrafunctional siloxane units, a finely divided hydrophobic filler, and from 75 to 900 parts by weight of a polyorganosiloxane polyoxyalkylene copolymer can be used as a stable suds-controlling composition for aqueous surfactant compositions, especially liquid detergents.
