Hydrogen Peroxide 25% Technical Grade

Product Overview

Hydrogen Peroxide 25% Technical Grade (H₂O₂) is a colorless, highly reactive oxidizing liquid widely used across chemical manufacturing, bleaching, water treatment, and analytical laboratories. This technical grade solution provides a strong oxidizing capacity with a typical assay of 25% and a color appearance close to standard references (APHA/Hazen color typically around 8, max 15). The product is supplied as an aqueous solution with a density around 1.11 g/mL at 25°C and a refractive index near 1.406, enabling predictable handling and dosing in process streams. Its pH typically ~4.5 in water allows compatibility with many inorganic and organic substrates while maintaining stability when stored under recommended conditions. Suitable for use in industrial processes, this solution demands careful management to prevent decomposition and ensure consistent performance.

Technical grade hydrogen peroxide is leveraged as a powerful oxidizing agent for oxidation-reduction reactions, bleaching, and disinfection steps across multiple sectors. The material is maintained under controlled conditions to preserve efficacy; iron and heavy metal impurities are monitored to ensure product quality (typical iron ≤0.05 ppm, heavy metals ≤0.005 ppm). The product’s decomposition temperature is a consideration in process design, with stabilization strategies recommended to keep the solution within safe operating temperatures below ~60°C for concentrated samples. This ensures reliable reactivity while reducing the risk of hazardous decomposition during storage and use.

Safety Precautions

Handle and store this product in a cool, dry place away from direct sunlight, with containers made of HDPE or glass to minimize container-oxide interactions. Maintain proper ventilation during handling and operation to minimize inhalation risks, and ensure that compatible PPE is worn, including chemical resistant gloves and splash-protective goggles. Keep containers tightly closed when not in use and segregate from organic materials and reducing agents to reduce the risk of hazardous reactions. Follow established handling procedures in accordance with your site’s safety program and local regulations.

Secondary safety considerations include recognizing its strong oxidizing nature and the potential for exothermic decomposition if exposed to heat or contaminants. Follow SDS guidance for emergency measures, use appropriate spill containment and neutralization protocols, and ensure that emergency eyewash and shower facilities are readily accessible. Refer to UN 2014 packaging and handling requirements for transport and ensure staff are trained in spill response, first aid, and emergency procedures for oxidizers. Always consult the Safety Data Sheet before use and implement the site-specific risk assessment for storage, usage, and disposal.
