Abstract

A process for the preparation of trialkanolamine di(fatty acid) esters in which a trialkanolamine is reacted with a fatty acid in the presence of small amounts of a fatty acid ester. The trialkanolamine fatty acid diesters obtained can be converted into the quaternary ammonium salt by means of standard quaternizing agents, and the resulting products can be employed as fabric conditioners.
