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.

A method useful for stabilizing a mono-amide of a fatty acid from crystallizing, comprising:
- adding to the mono-amide a reaction product of an aminoalkoxyalcohol and a dimerized or trimerized fatty acid.
A composition, comprising:
- a mono-amide of a fatty acid, and
- a reaction product of an aminoalkoxyalcohol and a dimerized or trimerized fatty acid.
A method useful for stabilizing a mono-amide of a fatty acid from crystallizing, comprising:
- adding to the mono-amide a reaction product of an amine and a dimerized or trimerized fatty acid, wherein the amount of reaction product is in the range from about 0.1 to 10 percent by weight based on the total weight of the mono-amide and the reaction product.
A composition, comprising:
- a mono-amide of a fatty acid, and
- a reaction product of a primary amine and a dimerized or trimerized fatty acid wherein the amount of reaction product is in the range from about 0.1 to 10 percent by weight based on the total weight of the mono-amide and the reaction product.
