ABSTRACT OF THE DISCLOSURE Water soluble mixed ester lubricants derived from triglycerides are obtained by transesterifying a triglyceride selected from animal oils or fats, or drying. Semi-drying or non-drying vegetable oils with a low molecular weight polyoxyethylene glycol having a molecular weight of 200-1000, preferably from 400-800 in the presence of short-chain mono- or dicarboxylic acids having from 2 to 12 carbon atoms. The mixed ester compositions are readily water soluble and are excellent lubricants for metal working operations. Water solubility is achieved with the mixed ester products even though they have higher triglyceride contents than previously known ester lubricants.
