Abstract

Abstract New compounds of the general formula II ##EQU1## in which one or two of the radicals R i (i = 1 to 7) stands for a linear or branched alkyl or alkenyl radical of 8 to 18 carbon atoms, one or two of the radicals R m (m = 2 to 6, m being ≠ i) stands for the radical of the formula A ##EQU2## and the other radicals R k (k = 1 to 7, k being ≠ i, m) stand for hydrogen or methyl, Y stands for hydrogen or an alkali metal ion, n is 2 or 3 and o and p are 0 or 1, their use as anti-microbially active surfactants in washing and cleansing compositions and disinfectants, and a process for preparing those compounds of formula II.
