Abstract
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.
