(57) [Problem] To develop a metal foaming oil composition with less foaming useful for plastic working such as rolling, drawing, ironing and drawing of metal. SOLUTION: A mineral oil or the like is used as a base oil, an alkylene oxide adduct of a polyhydric alcohol having 3 to 6 hydroxyl groups having a specific number average molecular weight (Mn), a hydroxyl group having 3 to 6 hydroxyl groups having a specific Mn. A specific amount of oxygen-containing compound (A) selected from hydrocarbyl ethers of alkylene oxide adducts of polyhydric alcohols, polyalkylene glycol of specific Mn, hydrocarbyl ether of polyalkylene glycol of specific Mn, carbon number It is characterized by containing a specific amount of an oxygen-containing compound (B) selected from 2 to 8 dihydric alcohols. |
