    Abstract: Defoamers in which the oil phase of the emulsions contains… (a) a C12- to C26-alcohol, distillation residues obtainable during the production of alcohols with a relatively high carbon number by oxo synthesis or by the Ziegler process and which may also be alkoxylated, and/or… (b) a fatty acid ester of C12- to C22- carboxylic acids with a mono- to tri-hydric C1- to C18-alcohol and optionally… (c) a hydrocarbon having a boiling point above 200 DEG C or fatty acids having 12 to 22 carbon atoms,… comprises 5 to 50% by weight of the make-up of the emulsion and has a mean particle size of less than 25 mu m, and in which 5 to 50 % by weight of the components (a) and (b) of the oil phase are replaced by… (d) at least one compound melting at a temperature above 70 DEG C selected from the group of fatty alcohols having at least 28 C atoms, the esters of a C1- to C22-carboxylic acid with an alcohol having at least 28 C atoms, the polyethylene waxes having a molecular weight of at least 2000, the carnauba waxes, the montanic ester waxes and the montanic acid waxes and their salts.

    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.
