PROBLEM TO BE SOLVED: To provide a water-soluble metalworking fluid composition formed by mixing a distillation residue generated during production of biodiesel and used as a lubricating base oil as the lubricating base oil with other additives in relation to an environmentally-acceptable water-soluble lubricating base oil which will substitute for a hydrocarbon-based lubricating base oil in cutting oil, as interest in the importance of environmental protection and health and safety for worker is increased. SOLUTION: The composition of an environmentally-friendly type water-soluble metalworking fluid is produced by adding 5-70 wt.% of an additive to 20-95 wt.% of the distillation residue generated during production of the biodiesel and used as the lubricating base oil and 0-40 wt.% of ion exchanged water.
