The effect of addition of cosmetic argan oil (CAO) on the corrosion of copper in 2 M H3PO4 and NaCl 0.3 M has been studied by weight loss measurements, potentiodynamic polarisation and Electrochemical Impedance Spectroscopy (EIS) measurements. The inhibition efficiency was found to increase with inhibitor content to attain 98% for CAO at 7g/L. Inhibition efficiency E (%) obtained from the various methods is in good agreement. The temperature effect on the corrosion behaviour of copper in (2 M H3PO4+ 0.3 M NaCl) was studied by potentiodynamic technique in theb range from 298 to 323 K. The associated activation energy has been determined.
