An emulsifiable oil composition comprises a hydrocarbon distillate containing (1) a non-ionic emulsifier; (2) a fatty acid having at least 8 carbon atoms; (3) an amino alcohol; and (4) a sulphamido carboxylic acid or its water-soluble salts. Specified emulsifiers are condensates of alkylene oxide with an aliphatic alcohol, an alkyl phenol, aliphatic carboxylic acids, partial esters of polyols, alkyl amines or polyamines, and with amides. Lists of suitable compounds are given and their relative amounts. Optional ingredients are nitriles, chromites, alkali carbonate and ozocerite. |
