    Abstract: The invention concerns mixtures suitable for use as fuel additives comprising essentially (A) at least one amine, polyamine or alkanolamine having a hydrocarbon group with a mean molecular weight of 500 to 10,000 and (B) at least one polyether amine of general formula (I) in which the variables are defined as follows: m is 1 or 2; n is 1 to 100; R1 is, when m = 1, a monovalent C6-C35 hydrocarbon group and, when m = 2, a bivalent C2-C30 hydrocarbon group; R2 and R3 are hydrogen, C1-C12 alkyl, C5-C7 cycloalkyl, C6-C10 aryl a polyalkylenamine group or an alkanolamine group with 1 to 5 nitrogen atoms (the groups can form, together with the nitrogen atom to which they are bound, a five- or six-membered ring which may include other heteroatoms, and the groups may be the same or different) and D is C2-C5 alkylene. The invention als concerns the use of such mixtures as fuel additives and fuels containing components A and B.

    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
