Abstract: The invention concerns the use, as anti-foaming agents in the paper industry, of alkoxylated amines or alkoxylated polyamines which each contain random ethylene oxide and propylene oxide blocks or ethylene oxide and propylene oxide units, the molar ratio of the ethylene oxide to the propylene oxide units being 1:4 to 1:20. The invention also concerns anti-foaming agents containing such alkoxylated amines and/or alkoxylated polyamines, at least one emulsifier with an HLB value of at least 8 and, optionally, up to 90 % by wt. of water.

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
