Abstract
Quaternary ammonium compounds containing one or two long-chain ester or amide radicals of etherified hydroxycarboxylic acids and, for the remainder, short-chain radicals, which are liquid to pasty substances that may readily be dissolved or dispersed in water or alcohol/water mixtures. They may be used in dilute or concentrated, storable form for softening fabrics without the absorbency of the treated fabrics being adversely affected. The quaternary ammonium compounds are obtained by reaction of epoxyfatty acid esters with amines and subsequent quaternization.
