摘要： The processing oil contains polycyclic aromatic hydrocarbon, which is a substance known to be toxic to the human body, in an amount of less than 3 wt. % and an aromatic hydrocarbon in an amount of 25 wt. % or more, and has a kinematic viscosity at 100null C. of 10-30 mm2/s, a density of 0.870-970 g/cm3, and a 5 vol. % recovery temperature of 370-530null C. The processing oil exhibits excellent performance which has conventionally been obtained. The processing oil can be produced by a method in which oil mixture comprising an extract obtained through extraction from mineral oil by use of a polar solvent in an amount of 40-97 vol. % and lubricating base oil in an amount of 3-60 vol. % is subjected to extraction treatment by use of a polar solvent.
