Abstract
Abstract Ammonium compounds of the formula ##STR1## in which R and R 1 designate C 1 -C 21 -alkyl or C 2 -C 21 -alkenyl, R' designates hydrogen or C 1 -C 4 -alkyl, R 2 designates C 1 -C 4 -alkyl or hydroxy-C 1 -C 4 -alkyl, R 3 designates hydrogen or C 1 -C 4 -alkyl and A.sup.⊖ represents an anion of the formula ##STR2## in which R 4 designates hydrogen, C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy and R 5 designates C 1 -C 4 -alkyl or C 1 -C 4 -hydroxyalkyl, a process for their preparation and their use as softeners for fibre materials.
