Foam control compositions along with formulations thereof and their use in various applications, including a method for making a foam control composition comprising a cross-linked polyorganosiloxane material including a dispersed silica filler, including the steps of:

Foam control composition

An anti-foaming agent containing (A) an organopolysiloxane and a finely powdered inorganic filler, (B) a polyoxyalkylene group-containing branched chain organopolysiloxane, and (C) an anionic surfactant. This anti-foaming agent exhibits stable anti-foaming performance even at high temperatures that reach, for example, 80QC or under strongly alkaline conditions and produces no aggregates.

Anti-foaming agent and pulp production method

In a process for separating a solid material from a suspension of the solid material in water, an organopolysiloxane polyalkylene oxide copolymer comprising a branched organopolysiloxane structure is added to the suspension of solid material in water and the suspension is drained. The organopolysiloxane polyalkylene oxide copolymer comprising a branched organopolysiloxane structure increases the rate of drainage of the suspension.
