Sodium metabisulfite (also known as disodium disulfite) is an inorganic sodium salt composed of sodium and disulfite ions in a 2 to 1 ratio. It has a role as a food antioxidant. Sodium metabisulfite is used in chemical processing to activate polymerization of acrylonitrile and in waste treatment to reduce chrome wastes. It is also used in fruit and vegetable processing as a bleach and preservative. In addition, it is used in photo processing as a preservative for thiosulfate fixing baths and as a reductant for reversal developing. It is also used in tanneries to accelerate the depilatory action of lime for unhairing hides. In the textile industry it is used as an antichlor following chlorine bleaching of cotton and following shrink-proofing of wool and as a mordant. It is also used in dye manufacture to inhibit oxidation of sensitive amine groups, to replace chlorine groups with the sulfite radical and as an aid in the formation of naphthylamine derivatives. Also, it is used in water treatment as an antichlor and in the manufacture of explosives and detergents.
