Mixtures of alkoxylates as foam-suppressing composition and their use

A mixture of alkoxylates as a foam-suppressing composition, consisting essentially of

• A) 10 to 90% by weight, of at least one fatty alcohol ethoxylate-propoxylate of the formula I
• R.sup.1 --O--(C.sub.2 H.sub.4 O).sub.x --(C.sub.3 H.sub.6 O).sub.y --H (I)
• in which R.sup.1 is an alkyl radical or an alkenyl radical having 6 to 22 carbon atoms, x is a number from 1 to 5, and y is a number from 1 to 6, and
• B) 10 to 90% by weight, of at least one fatty amine or fatty amine ethoxylate, or of a mixture thereof, of the formula II ##STR2## in which R.sup.2 is an alkyl radical or an alkenyl radical having 6 to 22 carbon atoms, and m+n is a number from 2 to 10, the percentages by weight being based on the mixture.
