    摘要: The invention is cleaning compositions containing Polyethylene-glycol ethers of the formulaR.sub.1 --(CH.sub.2 CH.sub.2 O).sub.n --R.sub.2 (1)in whichR.sub.1 is a straight-chain or branched alkyl- or alkenyl radical having from 20 to 28 carbon atomsR.sub.2 is an alkyl radical having from 4 to 8 carbon atoms and n is an integer from about 6 to about 20as a foam-suppressing additive. The cleaning compositions are stable over a broad temperature range and having low foaming characteristics particularly at about ambient temperatures.
