Abstract: In antifoams based on oil-in-water emulsions, the oil phase of the emulsions contains(a) a C.sub.12 -C.sub.26 -alcohol, a distillation residue which is obtainable in the preparation of alcohols having a relatively large number of carbon atoms by the oxo process or by the Ziegler process and which may furthermore be oxyalkylated and/or(b) a fatty acid ester of a C.sub.12 -C.sub.22 -carboxylic acid with a monohydric to trihydric C.sub.1 -C.sub.18 -alcohol and, if required,(c) a hydrocarbon having a boiling point above 200.degree. C. or a fatty acid of 12 to 22 carbon atoms,accounts for from 5 to 50% by weight of the emulsion and has a mean particle size of less than 25 .mu.m, and from 5 to 50% by weight of components (a) and (b) of the oil phase are replaced by(d) one or more compounds which melt at above 70.degree. C. and are selected from the group consisting of the fatty alcohols of not less than 28 carbon atoms, the esters of a C.sub.1 -C.sub.22 -carboxylic acid with an alcohol of not less than 28 carbon atoms, the polyethylene waxes having a molecular weight of not less than 2,000, the carnauba waxes, the montan ester waxes and the montanic acid waxes and their salts.

Abstract: In antifoams based on oil-in-water emulsions, the oil phase of the emulsion contains(a) C.sub.12 -C.sub.26 -alcohols, distillation residues obtained in the preparation of alcohols by an oxosynthesis or by the Ziegler process and/or(b) fatty acid esters of C.sub.12 -C.sub.22 -carboxylic acids with monohydric, dihydric or trihydric C.sub.1 -C.sub.18 -alcohols, with or without(c) a hydrocarbon having a boiling point above 200.degree. C. or fatty acids of 12 to 22 carbon atoms,constitutes from 15 to 60% by weight of the emulsion and has a mean droplet size of from 0.5 to 15 .mu.m. The emulsions are stabilized by the addition of from 0.05 to 0.5% by weight, based on the total emulsion, of a high molecular weight water-soluble homopolymer or copolymer of acrylic acid, methacrylic acid, acrylamide or methacrylamide.
