The influence of addition of the natural material, jojoba oil, on the corrosion of iron in molar hydrochloric acid had been studied using weight loss measurement and electrochemical polarisation methods. It was found that the corrosion rate was significantly reduced in the presence of jojoba. It was also found that the corrosion inhibition efficiency increased with the concentration of the jojoba oil to attain a 100 per cent inhibition at 0.515 g/l of jojoba oil, indicating that jojoba oil was an excellent corrosion inhibitor. The effect of temperature on the corrosion behaviour of iron indicated that the inhibition efficiency of jojoba oil decreased very slightly with the rise of temperature. It was found that the adsorption of jojoba oil on the iron, which followed the Frumkin isotherm, was the main cause to the corrosion inhibition.
