Abstract: Antifoams based on oil-in-water emulsions, in which the oil phase accounts for from 5 to 50% by weight of the emulsions and consists essentially of a mixture of (a) fatty esters of C12-C22-carboxylic acids with mono hydric to trihydric C1-C22-alcohols, (b) polyglyceryl esters which are obtainable by at least 20% esterification of polyglycerols which contain at least 2 glyceryl units with at least one C12-C36-fatty acid and (c) fatty esters of C12-C22-carboxylic acids and poly alkylene glycols, the molecular weight of the polyalkylene glycols being up to 5,000 g/mol, and, if required, (d) long-chain alcohols, fatty esters of alcohols of at least 22 carbon atoms and C1-C36-carboxylic acids, distillation residues which are obtainable in the preparation of alcohols having a relatively large number of carbon atoms by oxo synthesis or by the Ziegler process and which may be alkoxylated, and/or e) hydrocarbons having a boiling point above 200.degree.C or fatty acids of 12 to 22 carbon atoms, are used for controlling foam in pulp digestion, in the beating of paper stock, in papermaking and in the dispersing of pigments for papermaking.

Abstract: The invention relates to a process for tanning leather by using compounds of the general formula I where m is 0 or 1 and the radicals R are independently of each other C1-C18-alkyl, which may be substituted by hydroxyl or carboxyl and/or interrupted by oxygen atoms, or else one of the radicals R is a radical of the formula where R is alkylene, which may be substituted by hydroxyl and/or interrupted by oxygen atoms.

Abstract: In anti-foams for the paper industry, based on oil-in-water emulsions, the oil phase makes up 5 to 50 % by weight of the bulk of the emulsion and contains (a) an alcohol having at least 12 carbon atoms, fatty acid esters of alcohols having at least 22 carbon atoms and C1- to C36-carboxylic acids, distillation residues which are obtainable in the production of alcohols having a higher carbon number by oxo synthesis or by the Ziegler process and which may be alkoxylated, mixtures of the said compounds and/or (b) a fatty acid ester of C12- to C22-carboxylic acids with monohydric to trihydric C1- to C18-alcohols and, if appropriate, (c) a hydrocarbon having a boiling point above 200 DEG C or fatty acids having 12 to 22 carbon atoms in combination with (d) 1 to 80 % by weight of polyglycerol esters which can be prepared by an at least 20% esterification of polyglycerol mixtures which contain, as essential constituents, diglycerol, triglycerol, tetraglycerol and, if appropriate, more highly condensed polyglycerols, with saturated or unsaturated C12- to C36-fatty acids. i
