Green inhibitors are widely used due to their comparative advantage over other means of corrosion control and prevention. The inhibition efficiency of Pergularia daemia extract on the corrosion of mild steel in hydrochloric acid solution was measured by mass loss and thermometric method in the presence and in absence of inhibitor. It is concluded that the inhibition efficiency increased with the increase in inhibitor concentration. The investigation showed optimal inhibition efficiency up to 94.16% and can safely be used without pollution and any toxic effect.
