PROBLEM TO BE SOLVED: To use a water-soluble lubricant excellent in lubricity and wear resistance, which can be used in both a cupping (drawing) process and an ironing process in metal working such as cutting, plastic working, aluminum DI can forming, etc. A composition is provided. The water-soluble lubricant composition comprises 10 to 80% by weight of vegetable oil and fat, 10 to 50% by weight of a hydroxy fatty acid polycondensate, and 1 to 50% by weight of a nitrogen-containing cyclic compound. To do. For vegetable oils and fats, rapeseed oil is used. For hydroxy fatty acid polycondensates, those having an acid value of 30 to 120 are used. For nitrogen-containing cyclic compounds, N, N-di (hydroxyethyl) cyclohexylamine, N-ethylmorpholine, At least one selected from the group such as N-propylmorpholine, piperazine, aminoethylpiperazine, 1,4-bis (aminopropyl) piperazine is used.
