Weight loss method was used for studying corrosion behavior of iron in hydrochloric acid, with and without castor oil. It was observed that in acidic medium the % inhibition efficiency for corrosion increased with increasing castor oil concentration. The adsorption of castor oil on iron was found to follow the Langmuir adsorption isotherm at all concentrations.
