The present invention provides a liquid fuel composition comprising: a liquid base fuel suitable for use in an internal combustion engine; and one or more poly (hydroxycarboxylic acid) amide salt derivatives having formula (III) : [Y-CO [O-A- CO]n-Z r-R+] m pX q- (III) wherein Y is hydrogen or an optionally substituted hydrocarbyl group, A is a divalent optionally substituted hydrocarbyl group, n is from 1 to 100, m is from 1 to 4, q is from 1 to 4 and p is an integer such that pq = m, Z is an optionally substituted divalent bridging group which is attached to the carbonyl group through a nitrogen atom, r is 0 or 1, R+ is an ammonium group and X q- is an anion.

La présente invention porte sur une composition de combustible liquide comprenant : un combustible de base liquide approprié pour être utilisé dans un moteur à combustion interne ; et un ou plusieurs dérivés de sels d'amides de poly(acide hydroxycarboxylique) représentés par la formule (III) : [Y-CO[O-A-CO]n-Zr-R+]mpXq-(III) dans laquelle Y représente un atome dhydrogène ou un groupe hydrocarbyle facultativement substitué, A est un groupe hydrocarbyle facultativement substitué divalent, n vaut de 1 à 100, m vaut de 1 à 4, q vaut de 1 à 4 et p est un entier tel que pq = m, Z est un groupe en pont divalent facultativement substitué qui est attaché au groupe carbonyle par l'intermédiaire d'un atome d'azote, r égal 0 ou 1, R+ est un groupe ammonium et Xq- est un anion.
