摘要
The present invention is an antifoaming agent including: (A) an organopolysiloxane having a hydrolysable group shown by the formula (1) on at least one silicon atom of an organopolysiloxane segment constituting a main chain and containing siloxy units shown by the formula (2) at an amount of at least 10 mol% of the total, (B) a non-linear organosilicon resin other than the organopolysiloxane of component (A); and (C) a hydrophobic filler. This provides an antifoaming agent which has excellent foam control properties in washing (i.e., from washing to rinsing), is safe and inert to components in a detergent composition, and is more stable in various detergents; and a method for manufacturing thereof.(where X represents a divalent hydrocarbon group having 1 to 10 carbon atoms; and R each independently represents a hydrogen atom or a monovalent hydrocarbon group having 1 to 4 carbon atoms)(where R1represents a monovalent hydrocarbon group having 1 to 12 carbon atoms; and R2represents an organic group having an aryl group and 6 to 12 carbon atoms, optionally containing an oxygen atom or a halogen atom)
