Abstract
A suds-controlling composition of improved stability in aqueous surfactants, such as detergents, is disclosed comprising a silicon antifoam consisting essentially of a liquid branched polyorganosiloxane and a finely divided filler having a hydrophobic surface; a polyorganosiloxane polyoxyalkylene copolymer; and a cyclic organopolysiloxane. The silicone antifoam and polyorganosiloxane polyoxyalkylene copolymer are combined in a ratio of 1/3 to 3/1.
