Abstract

Abstract The invention relates to new cationic surfactants based on quaternary ammonium compounds which are characterized by the general formula ##STR1## wherein R 1 may be a linear or branched alkyl residue having from 1 to 22 carbon atoms; R 2 may be hydrogen or a linear or branched alkyl residue having from 1 to 21 carbon atoms, the total number of carbon atoms of the substituents R 1 and R 2 being in the range of from 8 to 22; R 3 and R 4 represent methyl, ethyl, 2-hydroxyethyl or 2-hydroxypropyl; R 5 represents an alkyl residue having from 4 to 6 carbon atoms or a phenalkyl residue having from 1 to 3 carbon atoms in the alkyl residue; and X - represents the anion of benzoic acid, of benzoic acid monosubstituted with CH 3 , NH 3 , NO 2 , COOH, OH or SO 3 H, of an aliphatic dicarboxylic acid having the general formula HOOC--(CH 2 ) n --COOH wherein n is a number from 2 to 8, of fumaric acid, of maleic acid or of sulfosuccinic acid; and the use of such cationic surfactants in industrial cleaning agents.
