About Caustic Soda

Caustic Soda, also known as Sodium Hydroxide, is an inorganic compound with the chemical formula NaOH. It is a highly caustic and reactive alkali that appears as white pellets, flakes, or granules and is also commonly supplied as a concentrated liquid solution. Caustic Soda is produced mainly through the electrolysis of brine (sodium chloride solution), which also yields chlorine and hydrogen as by-products. Due to its strong alkaline nature, it is widely used in chemical manufacturing, water treatment, and industrial cleaning processes.

This compound plays a critical role across numerous industries, including pulp and paper, textiles, detergents, food processing, and petroleum refining. It is a key ingredient in neutralising acids, producing soaps, and refining petroleum products. Because of its versatility and reactivity, Caustic Soda is considered one of the most important industrial chemicals globally.

Caustic Soda Uses

Chemical Manufacturing

Caustic Soda is an essential raw material in chemical manufacturing. It is used to produce a wide range of compounds, including sodium salts, detergents, and synthetic fibres. Its strong alkaline properties make it ideal for adjusting pH levels, facilitating reactions, and neutralising acidic by-products in various industrial processes.

Pulp and Paper Industry

In the pulp and paper sector, Caustic Soda is utilised in the pulping and bleaching processes. It helps break down lignin, a component of wood that binds cellulose fibres together, enabling the production of smooth, high-quality paper. It is also used to regenerate cellulose in the recycling of paper products.

Water Treatment

Caustic Soda plays a vital role in water treatment, where it is used to control acidity and remove heavy metals and impurities from wastewater. By raising the pH of water, it helps precipitate contaminants, allowing for cleaner and safer discharge or reuse of treated water.

Food and Beverage Processing

In the food industry, Caustic Soda is employed for food processing and cleaning. It is used to peel fruits and vegetables, process cocoa and soft drinks, and sterilise food processing equipment. Its effectiveness in removing organic residues and fats makes it a reliable cleaning agent in food-grade applications.

Cleaning and Industrial Maintenance

Due to its strong degreasing and saponification abilities, Caustic Soda is used in industrial cleaning and maintenance. It dissolves oils, fats, and protein-based deposits, making it ideal for cleaning tanks, pipes, and machinery across industrial facilities.
