Abstract: A drawing and stamping extreme pressure lubricant for steel and aluminum which comprises a water-in-oil micro-emulsion which consists essentially of about 2 to 30 percent of a 500 to 3,000 s.u.s. hydrocarbon oil and suitable emulsifiers and stabilizers used as the base for the emulsion including tall oil fatty acids, triethanolamine soaps, petroleum sulfonates, and non-ionic emulsifiers. By substituting an ethoxylated vegetable oil, such as caster oil, etc., for the hydrocarbon oil in the above formulation, a second extreme pressure lubricant is arrived at. Thus, this lubricant consists of 2 to 30 percent of an oxidized vegetable oil polymer where the oxidized portion is 4 to 30 moles selected from a group consisting of ethylene oxide (EO), propylene oxide (PO), and ethylene/propylene oxide (EO/PO) units of vegetable oil.
