RUSTPROOF OIL COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a rustproof oil composition which is excellent in rustproof properties, prevents stacked steel sheets satisfactorily from being rusted and is excellent in degreasing properties and treatability of waste water after degreased. SOLUTION: The rustproof oil composition includes 20-70 mass% vegetable oil, 0.5-40 mass% amine salt of a fatty acid, which is salt of the fatty acid with amine and has 16-40 total carbon atoms of the carbon atoms of the fatty acid and those of the amine, and 0.5-6 mass% compound shown by general formula (1): (R1)a-N-[(R2O)b-H]c(wherein R1is a 1-24C hydrocarbon group; R2is a 2-4C alkylene group; a and c are each 1 or 2 and a+c=3; b is an integer of 1-6) on the basis of the total mass of the rustproof oil composition.
