Application Guidance

Sodium Hypochlorite 2% (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: 直射日光を避け、涼しい場所で元の通気孔付き容器内に保管すること。酸、アンモニアおよび有機物から遠ざけること。時間や熱により濃度が低下する。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: 酸類（有毒な塩素ガスを発生する）；アンモニアおよびアンモニウム化合物（クロラミンを生成する）；還元剤；過酸化水素；有機物および可燃性物質；銅、ニッケル、コバルト、鉄などの金属（分解を促進する）。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.
