Abstract
There is disclosed a method for foam control wherein the antifoam agent is an emulsion gelled silicon composition prepared by first dispersing a curable liquid organopolysiloxane composition in a liquid continuous phase to form an emulsion and then curing the liquid silicone organopolysiloxane in-situ to a gelled state. Preferred compositions of the present invention find particular utility in the control of foam in aqueous detergent systems.
