The process comprises adding an amine compound selected from the group consisting of a) alkanolamines, b) aminocarboxylic acids and c) oligopeptides to a surfactant comprised of a member selected from the group consisting of nonionic and anionic surfactants. The amine compound is preferably selected from the group consisting of a) an alkanolamine containing 2 to 15 carbon atoms, b) an aminocarboxylic acid containing 2 to 8 carbon atoms, and c) an oligopeptide with an average molecular weight of 500 to 5000. The nonionic and anionic surfactants preferably contain 1 to 100 ethylene oxide units in the form of at least one polyethylene glycol chain. The amine compound is preferably added in a quantity of 50 to 6000 ppm, based on active substance of said surfactant.
