    Abstract: The invention provides for the paper industry an antifoam which is an oil-in-water emulsion at least as effective as the products used to date. The oil phase comprises: (a): one or more compounds selected from alcohols having at least 12C, fatty acid esters of alcohols having at least 22C and carboxylic acids having from 1 to 36C, and distillation residues optionally alkoxylated, the distillation residues being obtained in the preparation of alcohols having at least 8C by oxo synthesis or by the Ziegler process, and having a boiling point >= 200°C at 20 mbar; and/or (b): one or more fatty acid esters of carboxylic acids having from 12 to 22C with monohydric to trihydric alcohols having from 1 to 18C; and (d): from 1 to 80% by weight of polyglyceryl esters, wherein the oil phase makes up more than 50 but not more than 80% wt. of the oil-in-water emulsion.
