Overview
Sodium hypochlorite solution is one of the most widely used chlorine-based disinfectants globally. As an aqueous solution of NaClO, it's commercially available in concentrations ranging from 5% to 15% available chlorine. The pale yellow color indicates the presence of dissolved chlorine gas. First produced in 1789 by Claude Louis Berthollet, modern industrial production primarily involves reacting chlorine gas with sodium hydroxide solution. Its effectiveness against bacteria, viruses and fungi makes it indispensable in healthcare, water treatment and sanitation industries.
Physical and Chemical Properties
The solution has a characteristic chlorine odor and exhibits strong oxidative properties. Its stability depends on pH (optimal 11-13), temperature (degrades rapidly above 30°C) and light exposure (requires opaque containers). Under acidic conditions, it decomposes to release chlorine gas. The available chlorine content decreases by about 0.5-1% per month under proper storage. Industrial grades often contain sodium hydroxide to stabilize the solution and prevent metal corrosion during storage and transport.
Main Applications
In water treatment, it serves as both disinfectant and algicide at 1-5 ppm residual chlorine. The food processing industry uses it for equipment sanitation at 50-200 ppm concentrations. Healthcare facilities employ it for surface disinfection against pathogens like C. difficile. Textile industries utilize its bleaching properties for fabric treatment, while municipal applications include wastewater treatment and swimming pool sanitation. Emerging uses include odor control in waste management and mold remediation in buildings.
Safety and Storage
Proper storage requires HDPE or fiberglass-reinforced plastic containers, avoiding metals except certain stainless steel grades. Storage areas should be well-ventilated and temperature-controlled below 25°C. Spill response requires neutralization with sodium bisulfite or sodium thiosulfate. Never mix with acids or ammonia-containing products. Decomposition products include oxygen (fire risk) and chlorine gas (respiratory hazard). Emergency showers and eye wash stations are mandatory in handling areas.
B2B Procurement Guide
Industrial buyers should specify: available chlorine content (±0.5% tolerance), stabilizer content, heavy metal limits, and packaging specifications. Bulk shipments (road tankers or isotanks) offer cost savings for large-volume users. Quality verification should include titrimetric analysis for available chlorine and impurity testing. Consider regional suppliers to minimize transport time and degradation. Contracts should include provisions for product degradation compensation and delivery temperature controls.
