The invention relates to the use of fatty acid salts of alkoxylated oligoamines (I), whereby: A represents alkylene groups having 2 to 8 C atoms; R represents C7 to C23 alkyl groups or monounsaturated or polyunsaturated C7 to C23 alkenyl groups; Z represents C1 to C8 alkylene groupings, C3 to C8 cycloalkylene groupings or C6 to C12 arylene or aryl alkylene groupings; m represents 0 or a whole number ranging from 1 to 5, and the sum of all variables x has a value ranging from 50 % to 300 % of (m+3). Said fatty acid salts of alkoxylated oligoamines are used as lubricity improvers for petroleum products, especially for gasolines and middle distillates.
L'invention concerne l'utilisation comme agents améliorants du pouvoir lubrifiant pour produits pétroliers, notamment pour essence pour moteurs et pour distillats moyens, de sels d'acide gras d'oligoamines alcoxylées (I), A désignant des groupes alkylène ayant entre 2 et 8 atomes de C, R désignant des groupes alkyle C¿7?-C¿23? ou des groupes alkényle C¿7? à C¿23? insaturés une ou plusieurs fois, Z désignant des groupements alkylène C¿1? à C¿8?, des groupements cycloalkylène C¿3? à C¿8? ou des groupements arylène ou arylalkylène C¿6? à C¿12?, m valant 0 ou un nombre entier compris entre 1 et 5 et la somme de toutes les variables x comportant une valeur comprise entre 50 et 300 % de (m+3).
