Supplier Qualification Packet
One zipped download containing the TDS, SDS, latest lot COA (when available), and a fresh Letter of Continuing Guaranty for Sodium Hypochlorite 8.25%. Every file included is SHA-256 hashed and listed in a manifest your QA team can audit.
Application Guidance
Sodium Hypochlorite 8.25% (Technical) 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
- Store out of direct sunlight in a cool area, in the original vented container. Keep away from acids, ammonia and organic materials. Strength declines with time and heat.Adjudicated
- 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
- Acids (release toxic chlorine gas); ammonia and ammonium compounds (form chloramines); reducing agents; hydrogen peroxide; organic and combustible materials; metals such as copper, nickel, cobalt and iron (speed decomposition).Adjudicated
- Shelf Life
- 6 months from date of manufacture in sealed, original packaging
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.
