Abstract (en)

[origin: WO03020851A1] The invention relates to the use of fatty acid alkylene glycol esters, which are liquid at 21 DEG C, of general formula (I): R-COO-(AO)n-H, in which: R represents an alkyl radical or alkenyl radical with 5 to 19 carbon atoms; A represents groups CH2-CH2 or C3H6, and; n represents a number ranging from 0.5 to 6. These fatty acid alkylene glycol esters are used as an additive for improving the lubricity of diesel oil, particularly of low-sulfur diesel oil.
