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: Stabilised aqueous C14- to C22-alkyldiketene emulsions containing, as essential components, (a) 10 to 60 % by weight of at least one C14- to C22-alkyldiketene, (b) 1 to 10 % by weight of at least one protective colloid and (c) 0.1 to 20 % by weight of at least one ester of the formula in which R , R are C14- to C22-alkyl, in which case R and R must differ in the alkyl group by at least 4 C atoms, and/or denote identical or different C14- to C22-alkenyl groups, an ester of the formula R -O-CO-O-R (II), in which R and R are alkyl or alkenyl radicals having 2 to 22 C atoms or a urethane of the formula in which R , R and R are identical or different alkyl or alkenyl radicals having 2 to 22 C atoms, and the use of the compounds of the formula I to III as stabiliser for the preparation of alkyldiketene emulsions containing at least 10, preferably 16 to 40 % by weight of alkyldiketene in emulsified form.
