C5- to C15-alkanols are suitable for improving the defoamer action of a silicon-containing anti-foam in fuel oils, especially in biofuel oils, which comprise at least one additive with detergent action. Such alkanols are used in additive concentrates which also comprise aromatic hydrocarbons or hydrocarbon mixtures having a boiling point of 100 to 250° C. or C5- to C12-alkyl nitrates, and also silicon-containing antifoams, additives with detergent action and optionally commercial dehazers. |
