Abstract
A metal-working oil composition comprises as essential components thereof (a) one or more lube-oil components selected from the group consisting of oils, fats, mineral oils and fatty acid esters; and (b) one or more compounds selected from the group consisting of acidic phosphoric acid salts of aliphatic, alicyclic and aromatic amines each of which has 4 to 22 carbon atoms and quaternary ammonium salts formed from aliphatic or aromatic amines, each of which has 4 to 22 carbon atoms, and acidic phosphoric acids; and (c) a non-ionic surfactant. Incorporation of a specific amine compound together with a non-ionic surfactant permits, owing to the protective colloidal function of the compounds, stable dispersion of the lube-oil component as large droplets in water and hence the resulting dispersion enjoys good circulation stability and withstands severe machining conditions.
