Abstract

The invention provides the use of a surfactant as a corrosion inhibitor, wherein the surfactant is selected from derivatives of alkyl polyglucosides and derivatives of terpene alkoxylates, and mixtures thereof, provided that the derivatives are not sulfosuccinates. Also provided is a method of preventing or reducing corrosion of a metal component that is in contact with, or will be in contact with, an aqueous fluid, wherein the method comprises providing a surfactant and applying the surfactant to the metal component or adding the surfactant to the aqueous fluid that is in contact with, or will be in contact with, the metal component, wherein the surfactant is selected from derivatives of alkyl polyglucosides and derivatives of terpene alkoxylates, and mixtures thereof, provided that the derivatives are not sulfosuccinates.
