Abstract: Lubricating oil compositions comprising a base oil and a halogen containing ester of phosphoric acid having a specified structure in an amount in the range of from 0.01 to 5 parts by weight relative to 100 parts by weight of the base oil, and lubricating oil compositions further comprising an epoxy compound in an amount in the range of from 0.1 to 5 parts by weight relative to 100 parts by weight of the base oil.

Abstract: A metal working lubricant is disclosed for effective use in the working of metallic materials, particularly in cold rolling, which comprises the components of [I] an alkali metal salt, an alkaline earth metal salt, or a salt or amide of an amine or alkanolamine of a carbon number of 1 to 24, each said salt and said amide being derived from at least one acid selected from the group consisting of (1) an aliphatic mono- or di-carboxylic acid of 8 to 22 carbon atoms, or a polycarboxylic acid thereof, (2) a petroleum sulfonic acid, and (3) a naphthenic acid; [II] an alkylene glycol of the formula HO--C.sub.n H.sub.2n O.sub.m--H where m is an integer of 1 to 3, and n is an integer of 3 to 10; [III] water; and [IV] a mineral oil, a synthetic lubricant, a fat, a fatty oil or a combination thereof.
