Abstract
Abstract Water soluble lubricant compositions comprising alkanolamine and organic acid are improved by employing as the organic acid a partial acid amide of a dicarboxylic acid, such as mono-PRIMENE 81 R amide of succinic acid, mono-di-2-ethylhexylamide of maleic acid, mono-di-2-ethylhexylamide of methyltetrahydrophthalic acid and mono-di-2-ethylhexylamide of methylhexahydrophthalic acid as the organic acid.
