Sodium dithionite (CAS 7775-14-6, Formula: Na₂S₂O₄) is a powerful reducing agent widely used in textile dyeing auxiliaries. It functions by decolorizing vat dyes and discharging printed patterns through selective reduction of chromophores.
Store in cool, dry, well-ventilated areas away from oxidizers. Avoid inhalation of dust; wear PPE including gloves and goggles. Do not ingest; toxic if absorbed. Decomposes rapidly in acidic conditions releasing sulfur dioxide gas.
