The invention concerns the use of an oil composition for temporarily protecting and lubricating metal surfaces, characterised in that said composition contains: at least 30 % of at least a saturated or unsaturated C¿<=18? fatty acid triglyceride (Compound A); 5 to 30 % of at least a C¿<=18? fatty acid triglyceride with oleic acid content of at least 60 wt. % (Compound B); 5 to 30 % of at least an ester derived from condensation of a C¿1?-C¿12?, preferably, C¿1?-C¿2? aliphatic alcohol, with a C¿<=18? fatty acid (Compound C); and optionally 5 to 20 % of at least an amide derived from condensation of a C¿<=18 ?fatty acid, and a C¿2?-C¿6? mono- di- or tri-alkanolamine (Compound D). The invention also concerns a corresponding oil composition.
La présente invention concerne l'utilisation d'une composition huileuse pour protéger et lubrifier temporairement les surfaces métalliques, caractérisée en ce que ladite composition contient: au moins 30 % d'au moins un triglycéride d'acide gras en C <= 18, saturé ou insaturé (Composé A); de 5 à 30 % d'au moins un triglycéride d'acide gras en C <= 18 avec une teneur en acide oléique d'au moins 60 % en poids (Composé B); de 5 à 30 % d'au moins un ester dérivant de la condensation d'un alcool aliphatique en C1-C12, de préférence en C1-C2, avec un acide gras en C <= 18, (Composé C), et éventuellement de 5 à 20 % d'au moins un amide dérivant de la condensation d'un acide gras en C <= 18, et d'une mono- di- ou tri- alcanolamine en C2-C6 (Composé D). Elle vise également une composition huileuse correspondante.
