A method inhibiting metal corrosion in a closed water system such as is found in industrial, commercial and institutional systems which utilizes a formulation comprising at least one water soluble fatty acid salt of the formulae R COOX and R1 (COOX)¿n? wherein R is alkyl C6-18, or hydroxyalkyl (6-18), R?1¿ is alkyl C¿2-18? or hydroxyalkyl C2-18, X is a salt forming cation and n is 2 or 3. The corrosion inhibiting salt(s) is present in an amount 1 to 1000 parts per million parts of the aqueous treatment system. Other additives for helping to reduce corrosion of metal such as benzoates, silicates, nitrates, molybdates, triazole and the like may also be present. |
