Abstract
(EN)
The use as an anti-wear additive and/or friction modifier in a non-aqueous lubricant composition and/or in a fuel composition of at least one long chain fatty acid ester of a hydroxy carboxylic acid in which the long chain fatty acid has at least 4 carbon atoms and the ester is an oil-soluble ester of a mono- or poly- hydroxy carboxylic acid having 1 to 4 groups which are independently carboxylic acid groups or lower hydrocarbyl esters thereof and in which, when the hydroxy carboxylic acid is a mono-hydroxy carboxylic acid, the ester has a long chain fatty acid ester moiety of the hydroxy group of the hydroxy carboxylic acid and, when the hydroxy carboxylic acid is a poly-hydroxy carboxylic acid, the ester has independently long chain fatty acid ester moieties of one or two of the hydroxy groups of the poly-hydroxy carboxylic acid. Also, a non-aqueous lubricant composition and a fuel composition for an internal combustion engine which comprises at least one of said long chain fatty acid esters.

L'invention concerne l'utilisation en tant qu'additif anti-usure et/ou modificateur du coefficient de frottement dans une composition lubrifiante non aqueuse et/ou dans une composition de carburant d'au moins un ester d'acide gras à chaîne longue d'un acide hydroxycarboxylique dans lequel l'acide gras à chaîne longue contient au moins 4 atomes de carbone et l'ester est un ester soluble dans l'huile d'un acide mono- ou polyhydroxycarboxylique contenant 1 à 4 groupes qui sont indépendamment des groupes acide carboxylique ou leurs esters hydrocarbyliques inférieurs et dans lequel, lorsque l'acide hydroxycarboxylique est un acide monohydroxycarboxylique, l'ester comprend une fraction ester d'acide gras à chaîne longue du groupe hydroxy de l'acide hydroxycarboxylique et, lorsque l'acide hydroxycarboxylique est un acide polyhydroxycarboxylique, l'ester comprend indépendamment des fractions ester d'acide gras à chaîne longue d'un ou deux des groupes hydroxy de l'acide polyhydroxycarboxylique. L'invention concerne également une composition lubrifiante non aqueuse et une composition de carburant pour un moteur à combustion interne qui comprend au moins un desdits esters d'acides gras à chaîne longue.
