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-Zr-R<+>]mpX (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 is an anion.
