    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

    Abstract: Products of the condensation of sulphonated phenols, urea, further organic nitrogen bases and formaldehyde, obtainable by (A) sulphonation of phenols using from 1.0 to 1.5 mol of sulphuric acid per mole of phenol and (B) condensation of these sulphonation products with (a) from 0.5 to 1.8 mol of urea per mole of phenol, (b) from 0.001 to 0.5 mol of at least one further organic nitrogen base per mole of phenol, and (c) from 1.0 to 3.0 mol of formaldehyde per mole of phenol. The condensation products are suitable as tanning agents in the production of leather and pelts and as spray assistants for redispersible polymer powders.
