Abstract

The present invention relates to aqueous oil-in-water emulsion containing: a) an oil phase comprising at least one organic amine of the formula (I) R 1 -(NH-R 2 ) n -NH 2 (I) wherein n is an integer from 0 to 7, in particular 0, 1 or 2, R 1 is a linear or branched, acyclic hydrocarbon group having 12 to 22 carbon atoms; R 2 is C 2 -C 4 -alkanediyl; b) and water, wherein the amount of amines of formula (I) with n being 1 or 2 is at least 90 % by weight, based on the total amount of amines of the formula (I) contained in the oil phase. The invention also relates to the use of these emulsions as a corrosion inhibitor in water-bearing systems.
