A water-dispersible cooling and lubricating composition effective for use as a metal working fluid or a metal removal fluid. The composition comprises an oil and water emulsion prepared from a pre-emulsion concentrate having a high concentration of crude, degummed vegetable oil which can be combined with esters of such vegetable oil. The metal working fluid composition of the present invention is prepared by mixing the crude vegetable oil with alkyl esters as an antigumming agent, a corrosion inhibitor, a surfactant, a saponifier, a buffer, and a preservative to form a pre-emulsion concentrate. In a preferred embodiment of the invention, the pre-emulsion concentrate further comprises a fragrance. To form the desired metal working fluid composition of the present invention, the pre-emulsion concentrate is mixed with water to form a stable metal working fluid composition of the present invention.
