Abstract (en)

[origin: DE4436764A1] Guanidine salts of monounsaturated or polyunsaturated fatty acids with 6 to 44 C atoms are used to achieve a temporary anticorrosive protection of metallic surfaces. The guanidine salts are preferably dissolved in a oil-in-water emulsion. Also disclosed are oil-in-water emulsions whose oil phase may consist of various oil-like solvents that contain unsaturated fatty acid guanidine salts.
