Abstract: A lubricant for metal working comprises (1) an ester of tall oil and a polyhydric alcohol and (2) an ester of an acid derived from an animal or vegetable fat or vegetable or fish oil and/or pure fatty acids and a polyhydric alcohol, and, optionally, (3) an additive forming a protective layer on the metal. The tall oil may be refined, containing less than 20% of resin acids, which may be replenished with abietic acid or colophony and the polyhydric alcohol may be ethylene glycol, di- or triethylene glycol, polyethylene glycol of molecular weight 500 - 1500, polypropylene glycol, glycerol, a polyglycerol, pentaerythritol, sorbitol, or tri-methoxy propane. In forming the other ester the alcohol is chosen from this same selection while the acid may be obtained from wool fat, lard, tallow, bees-wax, lanolin, olive oil, sesame oil, soya oil, cotton seed oil, palm oil, coconut oil, or rape seed oil to which may be added or which may be replaced by pure lauric, myristic, palmitic, stearic, arachidic, oleic, elaidic, linoleic or linolenic acid. The additive (3) may be a chlorine, sulphur or phosphorus compound, e.g. chlorinated paraffins, pentachlorophenol, sulphur, sulphur chloride, sulphur oxychloride, diethyl sulphide, dioxyethyl sulphide, mercaptobenzthizaole, sodium mercaptobenzthiazole or tricresyl phosphate. Where compounds (1) and (2) only are present the weight ratio of (1):(2) may be 90:10 to 10:90. Where the additives (3) is also present constituents (1) and (2) each form 5 - 90% by weight and constituent (3) forms 5 - 50% by weight of the total. A mineral or synthetic lubricating oil may also be present.
