Sodium Hypochlorite 12.5%

Product Overview

Sodium Hypochlorite 12.5% is a highly concentrated aqueous solution widely utilized across heavy industrial sectors as a powerful oxidizing agent. Under normal conditions, this liquid solution appears as a colorless or slightly yellow watery liquid with a characteristic sweetish, bleach-like odor. With a molecular formula of ClNaO and a molecular weight of 74.44, this chemical serves as a critical processing aid in industrial environments. Alliance Chemical supplies this bulk Sodium Hypochlorite 12.5% chemical to meet the rigorous demands of modern manufacturing, ensuring consistent quality and stability in every container shipped.

This 12.5% concentration provides a robust active chlorine profile, making it far more efficient than standard commercial or consumer-strength alternatives. It mixes readily with water and is denser than water, with a density of 1.093 for a 5% solution, meaning it will sink in dilute systems. Industry professionals utilize this solution in applications ranging from pulp and paper bleaching to municipal and industrial wastewater processing where oxidation performance must be carefully controlled and monitored.

Why This Grade

Selecting the appropriate concentration of sodium hypochlorite is critical for process efficiency and equipment lifespan. The 12.5% concentration represents an industrial-strength sweet spot, providing maximum oxidative capacity while remaining stable during transport and short-term storage. Using a lower concentration, such as consumer-strength variants, introduces excess water into chemical formulations, which can dilute active reactants and cause severe failure modes in continuous-flow industrial reactors. Conversely, excessively concentrated formulations are highly unstable and degrade rapidly under ambient conditions.

Industrial facilities rely on this precise 12.5% concentration to maintain predictable reaction kinetics. Choosing an incorrect grade or concentration can result in under-oxidation of organic compounds in wastewater treatment systems, leading to process failure and non-compliance with local discharge regulations. Furthermore, incorrect dilution calculations can accelerate the corrosion of expensive pipeline infrastructure, particularly when handling delicate alloys. Selecting this professional-grade solution from Alliance Chemical ensures that your processes operate within designed tolerances, safeguarding equipment and stabilizing operating parameters.

Industrial Applications

• Wastewater Odor Control: Used in municipal and industrial facilities to oxidize odor-causing compounds, including hydrogen sulfide, ensuring standard air quality compliance in wastewater treatment operations.
• Pulp and Paper Bleaching: Serves as a key processing agent in the bleaching stage of paper manufacturing, helping to brighten cellulose fibers efficiently.
• Textile Processing: Applied as an industrial bleaching agent in fabric manufacturing to remove natural coloration from raw cotton and synthetic fibers.
• Industrial Laundry Systems: Utilized in commercial laundry facilities as a heavy-duty destaining agent to restore whites and remove persistent industrial organic soils.
• Chemical Synthesis: Acts as an essential intermediate and oxidizing agent in the production of various specialized organic and inorganic chemicals.

Hazmat & Shipping

Due to its chemical properties, Sodium Hypochlorite 12.5% is classified as a regulated hazardous material for transport. It is officially designated as UN1791, Hazard Class 8, Packing Group III. The proper shipping name is Hypochlorite solution. Under GHS standards, this material carries the signal word Danger. It poses significant risks of skin corrosion (H314) and serious eye damage (H318), alongside being highly toxic to aquatic life with long-lasting effects (H400 and H410). Consequently, transport must comply fully with DOT regulations governing corrosive liquids, and shipment must occur through authorized channels.

When handling this corrosive solution, operators must wear appropriate personal protective equipment (PPE). Given the GHS hazard statements H314 and H318, required gear includes chemical-resistant gloves (such as nitrile or neoprene), splash-resistant safety goggles, a face shield, and protective clothing to prevent any dermal contact. In areas with inadequate ventilation, a certified respirator is recommended to protect against irritating vapors. Proper spill containment and neutralization protocols must be established before unloading shipments to mitigate the risk of accidental release.

Handling & Storage

To maintain product stability and prevent rapid decomposition, Sodium Hypochlorite 12.5% must be stored in a cool, dry, well-ventilated area away from direct sunlight, ideally at temperatures below 20 °C (68 °F). Storage containers must be made of compatible materials such as high-density polyethylene (HDPE), PVC, or titanium; contact with metals like iron, copper, and nickel must be avoided as they catalyze decomposition. Furthermore, keep this liquid solution separated from incompatible substances, especially strong acids, ammonia, and organic compounds, to prevent the release of hazardous chlorine gas.
