A defoaming composition comprising about 1 to about 90% by weight of a mixture of at least three defoaming agents, (a), (b), and (c) and about 99 to about 10% by weight of at least two stabilizers (d) and (e) therefor, and optionally a carrier therefor, where defoamer (a) is selected from a hydrophilic, fumed, particulate silica; defoamer (b) is an ethylene oxide-propylene oxide block copolymer; and defoamer (c) is a linear alcohol alkoxylate mixture of poly(oxyethylene/polyoxypropylene) mono- C.sub.6, C.sub.8, and C.sub.10 alkyl ethers; stabilizer (d) is an ethoxylated C.sub.12-18 fatty alcohol having a molecular weight of about 820; and stabilizer (e) is a cross-linked (meth)acrylic acid polymer.
