Product Overview

Sodium Hypochlorite 12.5% is a clear, pale yellow liquid characterized by strong oxidizing properties, making it essential for demanding industrial environments. Commonly referred to as industrial bleach or liquid chlorine, the solution is prepared to deliver available chlorine content in the 12.5–13.0 wt% range (typical 12.8%). This concentration enables consistent performance across processes requiring rapid oxidation. Its density at 25°C is approximately 1.20 g/mL, with a boiling point around 101.5°C, ensuring predictable handling and dosing in large-scale systems.

This product is supplied with rigorous quality control, including titration-based assay verification and impurity profiling to minimize contaminants that could impact downstream reactions. The formulation is strictly designed for use in water treatment, pH adjustment, and oxidative processes in accordance with specifications. Sodium hypochlorite solutions are widely adopted in environmental engineering, chemical manufacturing, and laboratory settings where controlled oxidizing capacity is essential for process reliability.

Applications span from wastewater treatment to industrial textile bleaching and laboratory analytics. The product is compatible with HDPE and glass containers and must be stored in cool, dry environments away from direct sunlight to preserve stability. Proper handling requires appropriate PPE and adherence to SDS guidelines. This description reflects current TDS data to ensure trusted performance in critical operations.
