(NaOH)
Sodium hydroxide, commonly known as caustic soda or NaOH, is a highly versatile and widely used inorganic chemical. It is available in various purity grades, including industrial-grade (≥96%), food-grade (≥98%), and laboratory-grade (≥99%), meeting different requirements across multiple industries. The purity level ensures reliable chemical reactions, consistent quality, and compliance with both industrial and regulatory standards.
Sodium hydroxide is typically supplied in solid and liquid forms. The solid form, known as caustic soda flakes or pellets, is white, crystalline, and highly hygroscopic, while solutions are clear, colorless, and highly caustic. These forms are designed for safe transportation, easy handling, and suitability for diverse industrial applications. From production to end-use, the material maintains its chemical stability under recommended storage conditions. Analytical parameters, including moisture content, alkalinity, and purity, are strictly monitored to guarantee product quality.
Sodium hydroxide production adheres to ISO, ASTM, and ANSI standards, ensuring consistent chemical composition and safety. Quality control measures include purity testing, chloride and carbonate content checks, and moisture analysis, which are critical for industrial, chemical, and food applications. Certified suppliers provide Certificates of Analysis (COA) to validate compliance and product integrity.

Sodium hydroxide is offered in 25–50 kg bags, 500–1000 kg jumbo bags, drums, and bulk liquid tanks, depending on customer needs. Packaging is designed to protect the product from moisture, prevent caking, and facilitate safe transport and handling.
Sodium hydroxide is highly caustic and corrosive. Direct contact with skin, eyes, or mucous membranes can cause severe burns. Dust inhalation can irritate the respiratory tract. Appropriate personal protective equipment (PPE), including gloves, goggles, and protective clothing, is essential. Spills should be neutralized and contained immediately. Sodium hydroxide is generally manageable in the environment if properly diluted, but concentrated forms must be handled carefully to prevent harm to aquatic life or soil.
Sodium hydroxide should be stored in cool, dry, and well-ventilated areas, away from moisture, acids, and incompatible chemicals. Solid forms should be kept in sealed, corrosion-resistant containers to prevent caking and degradation, while liquid solutions require corrosion-resistant tanks. Proper storage ensures chemical stability, safety, and long-term usability.
Sodium hydroxide (caustic soda) is an essential industrial chemical with applications spanning chemical processing, water treatment, food, textiles, petrochemical, and pharmaceutical industries. Its availability in multiple grades and forms, combined with strict quality control and adherence to international standards, makes it a reliable and indispensable solution for industries worldwide. Proper handling, storage, and safety practices ensure efficiency, environmental responsibility, and operational reliability.
