Sodium hydrosulfite or Sodium dithionite, an Inorganic Chemicals, is a whitish to light yellow crystalline solid having a sulfur dioxide-like odor. Sodium dithionite spontaneously heats on contact with air and moisture. This heat may be sufficient to ignite surrounding combustible materials. Sodium dithionite is soluble in water. Under prolonged exposure to fire or intense heat containers of Sodium dithionite may violently rupture. Sodium dithionite is used in dyeing and to bleach paper pulp. Wuhan Ruisunny Chemical Co., Ltd has been focusing on trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide, Hydrogen Peroxide and Silane etc. since 2007. We hereby have following details for the product as:

Toxic and an irritant. An allergen. Flammable when exposed to heat or flame. Ignites on contact with water or sodium chlorite. To extinpsh fires, flood the reacting mass with water. Decomposes violently when heated to 19OOC and emits toxic fumes of SOx and NazO
4) Application:
Sodium dithionite is widely used in industry owing to its reducing properties and ability to react with oxygen. It is used in textile industry for dyeing, in the pulp and paper industry as a reducing bleach to remove yellow discoloration from cellulose based products, as an oxygen scavenger in boilers, in conservation to remove iron stains on cultural artifacts, and in water treatment for controlling iron flash on white fabrics in bleaching environments. It is also used in photographic film, clay, wine, leather goods, foods and beverages, polymers, cleaners, gas purification, environmental remediation, metal recovery, and chemical processing.
