Abstract
Abstract An emulsifiable concentrate for use in metal processing, especially in can forming, comprises an ester prepared from a polyalkenylsuccinic acid or anhydride, and a hydroxyl-containing amine. It is critical to the invention with respect to can forming that the acid or anhydride contain, in addition to its basic carbon length, a chain derived from an olefin having from 16 to 28 carbon atoms.
