Abstract: A water base metal working lubricant includes water soluble polyalkylene glycols, a water emulsifiable high pressure lubricant component, which may be a chlorinated paraffin or a sulfurized or chlorinated fatty acid ester, and a non-ionic or anionic emulsifier for the high pressure lubricant. The latter is provided by a salt of a fatty acid sulfonate or sulfate, or a phosphate organic acid or ester of a fatty acid. The mixture may also include anticorrosives and a bactericide.
