Beschreibung
Zusammenfassung:	The disclosure provides an additive for lowering the minimum usable temperature of a biodiesel fuel or a diesel/biodiesel blend, said additive comprising: at least one saccharide ester, and a polymer having a comb structure, wherein: if only one saccharide ester is present, said saccharide ester comprises at least one saturated ester group and at least one unsaturated ester group; and if more than one saccharide ester is present, these comprise a first saccharide ester comprising at least one saturated ester group and a second saccharide ester comprising at least one unsaturated ester group, whereby a combination of said additive with the biodiesel fuel or diesel/biodiesel blend at less than about 3.5% w/w of said additive has a cold filter plugging point which is reduced by at least about 2 Deg. C relative to said biodiesel is or diesel/biodiesel blend without said additive. The disclosure also provides a process for preparing said additive and its use in lowering the minimum usable temperature of a biodiesel fuel or a diesel/biodiesel blend.
