Potassium Metabisulfite
Potassium Metabisulfite, K2S2O5, is a white granular inorganic salt that dissolves in water to liberate sulfur dioxide gas, serving as a potent antioxidant and antimicrobial preservative. It has a sulfurous odor and is stable under dry conditions but decomposes in acidic media for controlled release applications.

Key in winemaking for sterilization and oxidation prevention; in pharmaceutical stabilizers for injectables; in textile dyes for color fixation; in food processing for fruit preservation; and in water treatment for chlorine neutralization in large-scale systems.
Releases irritating SO2 vapors triggering asthma attacks; corrosive to skin in wet forms. Acid interactions produce toxic gases; equip workspaces with gas detectors and respiratory protection, following strict exposure limits.
Contained in 25 kg multi-ply polyethylene bags with valve closures for easy dispensing. Ventilate storage silos, keeping distant from acidic inventories.
