The invention relates to the use of carboxylic acid diesters, in particular for treating material, and more particularly for cleaning paint stains on textile fibres in order to improve the cleaning performance. According to the invention, the formulation comprises at least one dicarboxylic acid diester of formula (I) R1-OOC-A-COO-R2 in which the groups R1 and R2 are the same or different and represent a linear or branched, cyclic or non-cyclic C1-C20 alkyl, aryl, alkyaryl, or arylalkyl group; the group A represents a linear or branched divalent alkylene group; and at least one non-ionic polyalcoxylated terpene surfactant.

L'invention concerne des formulations de diesters d'acide carboxylique particuliers pour le traitement de matériaux, et plus particulièrement pour le nettoyage de souillures de peinture sur des fibres textiles, dans le but d'amélioration les performances de nettoyage. Selon l'invention, la formulation comprend: - au moins un diester d'acide dicarboxylique répondant à la formule (I): R1-OOC-A-COO-R2 (I) où les groupes R1 et R2, identiques ou différents, représentent un groupe alkyle, aryle, alkyaryle, ou arylalkyle, linéaire ou branché, cyclique ou non cyclique, en C1-C20, le groupe A représente un groupe alkylène divalent linéaire ou branché, et au moins un tensioactif non ionique terpène polyaloxylé.
