Applications & Use Cases
- ▸ Reducing and bleaching agent in textile dyeing, used to reduce vat and sulfur dyes to their soluble leuco form and to strip or correct off-shade dyed cotton and cellulosic goods.
- ▸ Brightening and reductive bleaching agent in pulp and paper processing, including deinking of recycled fiber and color stripping of dyed broke.
- ▸ Reducing agent and oxygen scavenger in industrial synthesis, where it serves as a milder, more stable alternative to sodium dithionite (hydrosulfite) for reductive reactions.
- ▸ Reductant in metal recovery and electroless plating baths, and for reduction of metal ions in specialty chemical manufacturing.
- ▸ Reductive agent for color removal and decolorization in clay, kaolin, and mineral processing for coatings and construction fillers.
