    Abstract: A mixture is disclosed of at least two alkoxylated alcohols and having the formula (I), in which x is a number between 1 and 12 and y is a number between 1 and 15. One alkoxylated alcohol has as residue R a straight-chain or branched-chain C8-C18-alkyl group and the other alkoxylated alcohol has as residue R a straight-chain or branched-chain C10-C20-alkyl group, but the average number of C atoms in the residues R must differ by at least 0.5, whereas the ratio between both alkoxylated alcohols is comprised between 10 : 90 and 90 : 10. This mixture is suitable as an antifoam tenside additive in cleaning products for machine washing processes.

    Abstract: The compositions contain as essential components… (a) 1 to 20% by weight of at least one non-ionic surfactant based on alkoxylated fatty alcohols, fatty acids, fatty amines, fatty acid amides or alkanesulphonamides,… (b) 0.1 to 15% by weight of at least one polyether polyol which is obtainable by reaction of 2 to 6-hydric alcohols, which have 2 to 10 C atoms, with alkylene oxides containing 2 to 4 C atoms, and reaction of these reaction products with 1,2-alkylene oxides, alkyl or alkenyl glycidyl ethers containing 8 to 30 C atoms and… (c) 1 to 40% by weight of at least one acid.

    Abstract: PCT No. PCT/EP92/00289 Sec. 371 Date Aug. 23, 1993 Sec. 102(e) Date Aug. 23, 1993 PCT Filed Feb. 11, 1992 PCT Pub. No. WO92/14808 PCT Pub. Date Sep. 3, 1992.A mixture suitable for use as a foam-suppressing surfactant additament in cleaning compositions for mechanized cleaning processes comprises at least two mixtures of alkoxylated alcohols I R-O-(C2H4O)x-(C3H6O)y-H (I) where x is an average degree of ethoxylation between 1 and 12, y is an average degree of propoxylation between 1 and 15, one alkoxylated alcohol mixture carries straight-chain or branched C8-C18-alkyl groups as the radical R and one other alkoxylated 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 alkoxylated alcohol mixtures present in a ratio of from 10:90 to 90:10.
