Abstract: An aqueous base lubricant composition particularly useful as a post pickle and rolling fluid for steel comprising an aqueous dispersion of (1) a water miscible fluid which is the condensation product of from 1.5 to 2 moles of a dialkanol amine which is either diethanolamine or diisopropanolamine and one mole of a monocarboxylic acid containing 10-20 carbon atoms, or glyceride thereof, and (2) an agent for reducing the viscosity of the aqueous composition which is either (a) an alkyl aryl sulfonate, (b) a monoalkyl ether of a lower alkylene glycol, (c) a lower glycol, or (d) a monoalkyl ether of a polyoxyalkylene glycol. The lubricant compositions may contain extreme pressure or antifriction additives as well as materials which enhance the rust and corrosion protection provided by said compositions.
