A composition comprises a poly(oxyalkylene)glycol derivative and a long chain anhydride and optionally a hydroxy-oxime. The long chain anhydride can be an alk(en)yl succinic anhydride in which the alk(en)yl group contains at least six carbon atoms. The optional hydroxy-oxime can be an alkyl-substituted benzaldoxime. The composition has improved corrosion resistance and can provide protection of a metal even in the form of a thin film.
