    Abstract: Preparation of mixture of alkoxylated alcohols and use thereof as a foam-suppressing surfactant additament in cleaning compositions for mechanized cleaning processes. Preparation of a mixture of alkoxylated alcohols I R-O-(C2H4O)x-(C3H6O)y-H (I) where x is an average degree of ethoxylation of from 1 to 12 and y is an average degree of propoxylation of from 1 to 15, comprises mixing at least two mixtures of alcohols of the general formula R-O-H where one alcohol mixture carries straightchain or branched C8-C18-alkyl groups as the radical R and one other alcohol mixture carries straight-chain or branched C10-C20-alkyl groups as the radical R, subject to the proviso that the two radicals R differ by at least 0.5 in the average number of carbon atoms, and the two alcohol mixtures are present in a weight ratio of from 10:90 to 90:10, with one another and reacting this mixture first with the corresponding amount of ethylene oxide and then with the corresponding amount of propylene oxide. This mixture is useful as a foam-suppressing surfactant additament in cleaning compositions for mechanized cleaning processes.
