Abstract
This invention concerns a composition containing a dimerized or trimerized fatty acid amide of a primary alkanolamine that remains clear of suspended solids during storage, making mixtures containing the additive particularly useful to the metalworking industry. The amide may be formed by the condensation of a primary alkanolamine and a dimerized or trimerized fatty acid. When added to an amide of a primary alkanolamine and fatty acid containing a single carboxylic acid group, these molecules are able to prevent crystallization of the amide mixture.
