FIELD: chemistry.

SUBSTANCE: invention relates to a poly(hydroxycarboxylic acid) amide salt derivative of formula (III), a lubricant composition and a fuel composition containing a poly(hydroxycarboxylic acid) amide salt derivative and use of the poly(hydroxycarboxylic acid) amide salt derivative. In general formula (III) [Y-CO[O-A-CO]_n-Z-R⁺]_m pX^q-, Y is hydrogen or an optionally substituted hydrocarbyl group, A is a divalent optionally substituted hydrocarbyl group, n ranges from 1 to 100, preferably from 1 to 10, m ranges from 1 to 4, q ranges from 1 to 4 and p is an integer provided that pq=m; Z is an optionally substituted divalent bridge group which is bonded to a carbonyl group through a nitrogen atom, R⁺ is an ammonium group and X^q- is an anion which does not contain sulphur, selected from a group consisting of OH, phenolate groups, salicylate groups, oleate groups and combinations thereof.

EFFECT: reduced phosphorus volatility of the lubricant composition.
