Sodium Hypochlorite 12.5%

Product Overview

Sodium Hypochlorite 12.5% (Technical Grade) is a clear, pale yellow liquid with strong oxidizing properties suitable for demanding industrial environments. The solution is prepared to deliver available chlorine content in the 12.5–13.0 wt% range (typical 12.8%), enabling consistent performance across processes that require rapid oxidation and disinfection. Its density at 25°C is approximately 1.20 g/mL, and the boiling point is around 101.5°C, supporting predictable handling and dosing in large-scale systems. The product is supplied with rigorous quality control, including titration-based assay verification and comprehensive impurity profiling to minimize contaminants that could impact treatment efficacy or downstream reactions. The formulation is designed for use in water treatment, pH adjustment, and oxidative processes in accordance with Technical Grade specifications. Sodium hypochlorite solutions are widely adopted in environmental, chemical manufacturing, and laboratory settings where controlled oxidizing capacity is essential for process reliability and safety.

Applications span from drinking water and wastewater treatment to industrial bleaching and laboratory analytics. The product is compatible with HDPE and glass containers and is intended for storage in cool, dry environments away from direct sunlight to preserve stability. Proper handling requires appropriate PPE and adherence to SDS guidelines to mitigate irritation and oxidative hazards. This description reflects current TDS data, including assay, color, and impurity profiles, to ensure trusted performance in critical operations while aligning with industry expectations for quality and traceability.

Safety Precautions

Handle with appropriate PPE including chemical splash goggles, face shield if splashes are possible, chemical-resistant gloves, and protective clothing. Store in a cool, dry place away from direct sunlight, acids, and organic materials, using containers made of HDPE or glass. Ensure proper ventilation in storage areas to minimize vapor buildup. The material is a strong oxidizer and can pose risks of skin and eye irritation with potential for severe burns on contact; avoid inhalation of vapor and breathing difficulty. Regularly inspect storage containers for signs of degradation and follow established handling procedures per the SDS.

Additional safety considerations include monitoring for exposure limits, maintaining inert atmosphere when required, and adhering to emergency procedures in the event of spills or accidental release. Immediate steps include evacuating unprotected personnel, containing the spill, and consulting the SDS for first-aid actions such as eye rinsing, skin decontamination, and medical attention if exposure occurs. Transport should follow UN 1791 guidelines for hypochlorite solutions (Class 8, PG II).
