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.
至少一个长链脂肪酸羟基羧酸酯在非水润滑剂组成中作为抗磨添加剂和/或摩擦改性剂的用途,或在燃料组成中使用,其中长链脂肪酸至少有4个碳原子,酯是一种油溶性单糖或多糖羟基羧酸的酯,其中1到4个独立的羟基是羧酸基或其较低的烃基酯,当羟基羧酸是单羟基羧酸时,酯具有羟基羧酸的羟基的长链脂肪酸酯基团,当羟基羧酸是多羟基羧酸时,酯具有多羟基羧酸的一个或两个羟基的独立长链脂肪酸酯基团。同时,一种非水润滑剂组成和一种燃料组成,用于内燃机,其中至少包括上述的长链脂肪酸酯之一。
