Disclosed is an aqueous deicing and/or anti-icing composition, and the use thereof on areas in need of deicing and/or anti-icing, exhibiting substantially improved corrosion inhibition, conductivity inhibition and/or hydrogen embrittlement inhibition. Said composition comprises 40-60% by weight of at least one alkali metal carboxylate, 0.1-0.5% by weight of benzoic acid and/or at least one alkali metal benzoate, 0.05-0.5% by weight of at least one alkali metal phosphate, 0.005-0.05% by weight of at least one alkali metal metasilicate, and 0.01-0.15% by weight of succinic acid and/or at least one alkali metal succinate. Balance to 100% by weight is water and said composition is pH adjusted to pH 9-12 by addition of at least one alkali metal hydroxide and/or carbonate. Disclosed is also a method of obtaining corrosion inhibition, conductivity inhibition and/or hydrogen embrittlement inhibition by addition of 0.01-0.15% by weight of succinic acid and/or at least one alkali metal succinate to an aqueous deicing and/or anti-icing composition.
