The invention relates to C5- to C15-alkanols which can be used to improve the defoaming effect of a silicon-containing anti-foaming agents in fuel oils, in particular in bio-fuel oils, which contain at least one additive having a detergent effect. Said type of alkanols are used in additive concentrates which contain, in addition to aromatic hydrocarbon or hydrocarbon mixtures having a boiling point of between 100 - 250°C or C5- to C12-alkyl nitrates and silicon-containing anti-foaming agents, additives having a detergent effect and optionally commercially available dehazers. |
