Abstract

A corrosion inhibited composition comprises an aqueous drilling, cutting, or polishing agent, an aqueous hydraulic fluid or an aqueous antifreeze compound; and an alkali metal salt, or an aliphatic amine salt of a mixture of 2- and 3-C.sub.6-12 -alkyladipic acids, the amount of this acid component being effective as a corrosion inhibitor.
