Abstract

1. The use of sulfur-containing hydroxycarboxylic acids corresponding to the following general formula see diagramm : EP0025125,P8,F1 in which R**1 is an alkyl radical containing from 6 to 16 carbon atoms and preferably from 6 to 12 carbon atoms, R**2 is an alkyl radical containing from 1 to 3 carbon atoms and n=1 or 0, or water-soluble salts thereof for preventing the corrosion of metals in aqueous systems in the pH range from 6 to 9, more particularly in industrial water systems.
