Menthol has been studied as a vapor phase corrosion inhibitor for the temporary protection of mild steel in a NaCl environment. Its vapor corrosion inhibition property was gravimetrically evaluated in 100% relative humidity (RH) at 40±1 ºC by a continuous condensation method. Electrochemical properties, such as Tafel polarization and AC impedance, of menthol impregnated craft paper was studied by a thin layer technique using an atmospheric corrosion monitor. It has been found from the results that the inhibition efficiency of menthol increases with an increase in the concentration of menthol from 250 mg/sq.ft to 1,000 mg/sq. ft. The adsorption behavior of menthol on mild steel surface was found to obey Temkin’s adsorption isotherm.
