Application Guidance

Sodium Chlorite Flakes 80% - ACS Grade (ACS) is supplied for applications where controlled, selective oxidation is required. Grade selection drives the choice between bulk industrial oxidation, electronics/semiconductor cleaning, and pharmaceutical-grade disinfection.

Pulp and textile bleaching
Wastewater treatment and odor control
Etching and surface cleaning (electronics-grade only)
Disinfection and sterilization (food/pharma-grade only)
Chemical synthesis and polymerization initiation

Materials of construction must be rated for the concentration and temperature in service. Avoid contact with reducing agents, transition metals, and organic combustibles.

Storage & Handling

Recommended Storage: Cool, well-ventilated area, away from heat, sunlight, and combustibles. Vented containers only — pressure may develop from slow decomposition. Original sealed containers; segregate from organics, metals (especially copper, iron, manganese), and reducing agents.Class-level guidance — not product-specific; the SDS controls.
Handling Precautions: Use PPE including face shield, chemical-resistant gloves, and apron. Avoid contamination — never return unused material to the original container. Ground all transfer equipment.Class-level guidance — not product-specific; the SDS controls.
Incompatibilities: Combustible materials, organic compounds, reducing agents, transition metal salts (catalytic decomposition), strong bases.Class-level guidance — not product-specific; the SDS controls.
Shelf Life: 60 monthslobachemie.com

For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
