Abstract

A process for the quaternization of triethanolamine fatty acid esters and imidazolinamides with customary quaternizing agents in a reaction medium containing alkoxylated naturally occurring fats or oils, or mixtures thereof with free fatty acids, monoglycerides and/or diglycerides in the substantial absence of 2-propanol, and the use of the resulting reaction mixtures as the active components in laundry softener compositions.
