Detergent defoaming agent composition (A) (Aa) Formula (I): R 1 R 2 SiO 2 / 2 , wherein R 1 is a monovalent, optionally branched, SiC-bonded
hydrocarbon group having 1 to 5 carbon atoms, and R 2 is a monovalent, optionally branched, SiC-bonded
hydrocarbon group having 6 to 30 carbon atoms, a polysiloxane containing units, (Ab) a filler, (Ac) General formula (II): R 3 a (R 4 O) b SiO (4-a-b) / 2 , wherein R 3 is a monovalent, optionally substituted, SiC-bonded
hydrocarbon group having 1 to 30 carbon atoms, and R 4 is a
hydrogen atom or a monovalent, optionally substituted, hydrocarbon group having 1 to 4 carbon atoms, a is 0, 1, 2 or 3, b is 0, 1, 2 or 3, provided that the sum of a + b is ≦ 3, and in less than 50% of all the units of formula (II), the sum of a + b = 2, an organopolysiloxane resin composed of units, optionally further organopolysiloxane (Ad), optionally a water-insoluble
organic compound (Ae), and optionally a catalyst (Af) 100 parts by
mass of a defoaming agent, (B) not containing a polysiloxane-containing additive, and containing less than 5% by
mass of a triester (B'') of
glycerol and a
fatty acid, 10 to 45 parts by
mass of a
wax-like additive containing a monoester (B') of
glycerol and a
fatty acid, (C) 10 to 50 parts by mass of a polycarboxylate binder having a pH of 3 or less when dissolved in water, (D) at least one powdered
carrier material, provided that the
carrier material contains less than 50% by mass of an alkaline
carrier material, 120 to 5000 parts by mass of a powdered carrier material, to describe a novel defoaming agent
powder.
