Abstract
Abstract Disclosed is a water-soluble coolant for formation of drawn and ironed cans, which comprises an aqueous solution containing 0.1 to 20% by weight of a phosphorus-containing compound obtained by esterifying an epoxidation product of at least one higher unsaturated fatty acid or its ester with phosphoric acid.
