Abstract
A metal working water-soluble lubricant composition comprising a water-soluble polymer compound whose counter anion is acidic phosphorus-containing compound or boric acid is disclosed. The water-soluble polymer compound is selected from the group consisting of cationic or amphoteric addition polymers, ring-opened polymers, polycondensation products and salts or quaternary ammonium salts of natural polymer derivatives having at least one basic or cationic nitrogen atom in one molecule thereof with a molecular weight of 1,000 to 10,000,000. The composition has a load resistance equal to or higher than known liquid lubricants which contain mineral oils, beef tallow etc., and shows an excellent lubricating performance when applied to a metal working surface.
