metamsodium

Metamsodium, chemically known as sodium chlorite (NaClO₂), is an inorganic compound widely used as a disinfectant and sanitizer. It is typically sold as a white or off-white powder that dissolves readily in water. The compound is derived from sodium chlorate (NaClO₃) through a reduction process, often involving hydrogen peroxide or other reducing agents.

Metamsodium is primarily utilized in the food industry as a sanitizing agent for equipment and surfaces to control microbial growth. It is effective against a broad spectrum of bacteria, viruses, and fungi, including pathogens such as *E. coli*, *Salmonella*, and norovirus. Due to its strong oxidizing properties, it breaks down organic contaminants and inactivates microorganisms upon contact.

In addition to food processing, metamsodium is employed in other sectors such as agriculture, where it is used to sanitize irrigation water and soil to prevent disease transmission. It is also utilized in municipal water treatment systems, though its use is regulated due to potential environmental and health concerns.

The compound decomposes in water to release chlorine dioxide (ClO₂), a potent disinfectant. However, its application requires careful handling, as improper use can lead to the release of toxic gases or residues. Safety protocols, including proper dilution and ventilation, are essential to minimize risks.

Metamsodium is generally recognized as safe by regulatory agencies when used according to established guidelines. However, exposure to high concentrations may cause skin or respiratory irritation, and ingestion can be harmful. Proper storage in sealed containers and adherence to manufacturer instructions are recommended to ensure safe and effective use.
