Abstract
A lubricant composition comprises (1) at least one member selected from the group consisting of carboxylic acid compounds each obtained by the addition of an oxyalkylene group to a hydroxyl group of a hydroxy carboxylic acid and alkali metal salts and amine salts thereof; and (2) at least one base oil selected from the group consisting of alkyl benzene, normal paraffin, isoparaffin and &agr;-olefin. The lubricant composition is highly resistant to putrefaction when it is used as a metal-processing oil composition and shows excellent cutting characteristics in the metal-processing, which requires an extremely high lubricating action, such as form-rolling tap and deep hole boring. Moreover, the composition makes operations such as metal-processing operations easy since the liquid obtained by diluting it with water is transparent or translucent.
