Abstract: A metal-working oil composition containing:- (A) one or more lube-oil components which are oils and fats, mineral oils or fatty acid esters; and (B) one or more polyetherpolyol dispersants which are made by adding alkylene oxides to polyalkylene- imines or -polyamines, alkyl- or alkylaryl-amines, or carboxylic acid amides, or their derivatives, e.g. polyetherpolyol derivatives having molecular weights of 300 to 600,000 and obtained by adding alkylene oxides to polyalkyleneimines. Incorporation of the polyetherpolyol permits, owing to its protective colloidal function, 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.
