SODIUM CHLORITE

Sodium Chlorite is an inorganic, highly reactive oxidizing agent used primarily for bleaching, disinfection, water purification, antimicrobial formulations, and specialty chemical synthesis.
Sodium Chlorite is valued for its ability to generate chlorine dioxide under controlled conditions, making it a powerful disinfectant used in municipal water treatment, food processing, sanitation, and industrial applications.
Sodium Chlorite provides strong antimicrobial action against bacteria, viruses, fungi, and biofilms, and is widely incorporated into surface disinfectants, deodorizing solutions, and cleaning agents.
Sodium Chlorite is chemically stable in alkaline solutions but decomposes under acidic conditions to release chlorine dioxide, enabling versatile use in controlled oxidation reactions.
