Chemical Profile

Product Overview

Sodium Hypochlorite 8.25% is a pre-diluted aqueous solution of sodium hypochlorite (NaOCl) prepared with high-purity deionized water. This 8.25% concentration provides a convenient, ready-to-use form that eliminates the need for on-site dilution of concentrated stock. Appearance: Yellow-green liquid with strong chlorine odor. This Technical Grade product is manufactured for industrial and commercial applications where high purity is required for consistent performance.

Supplied by Alliance Chemical in sizes ranging from 1 quart to 330-gallon IBC totes, this solution is ideal for operations requiring consistent 8.25% strength with minimal handling risk compared to higher concentrations.

Common Applications

Water Treatment: Oxidizer dosed into municipal water, pool, and cooling-tower systems.
Surface Treatment: Oxidizing agent used on equipment and facility surfaces.
Wastewater Treatment: Used for oxidation of organic contaminants and cyanide destruction in effluent.
Laundry & Textile Bleaching: Effective whitening and stain removal agent for commercial and institutional laundry operations.
Food Processing: Used in produce-wash and CIP systems where an oxidizer is specified. Confirm suitability against your own process requirements.

Safety Precautions

Sodium Hypochlorite is an oxidizer and is corrosive to skin and eyes. Never mix with acids or ammonia — doing so releases toxic chlorine or chloramine gas. Handle in well-ventilated areas with appropriate PPE. Store in a cool, dark location in original HDPE containers.

PPE Requirements: Wear chemical-resistant gloves, splash goggles, and protective clothing. Avoid breathing vapors. In case of skin or eye contact, rinse immediately with large amounts of water for at least 15 minutes. Refer to the Safety Data Sheet (SDS) for detailed handling, storage, and emergency response procedures.

Shipping: UN 1791, Hypochlorite solution, Class 8, PG II/III.

Benefits

Ready-to-Use Strength: Pre-diluted to a known available-chlorine concentration, so no in-house dilution step is required.
Consistent Oxidizing Strength: Available-chlorine concentration verified per lot on the certificate of analysis.
Cost-Effective Supply: Available from small bottles to bulk totes for economical treatment operations.
