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) R1—(NH—R2)n—NH2 ??(I) wherein n is an integer from 0 to 7, in particular 0, 1 or 2, R1 is a linear or branched, acyclic hydrocarbon group having 12 to 22 carbon atoms; R2 is C2-C4-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.
