Caustic soda (sodium hydroxide) is a versatile alkali. Its main uses are in the manufacture of pulp and paper, alumina, soap and detergents, petroleum products and chemical production. Other applications include water treatment, food, textiles, metal processing, mining, glass making and others. Around three-quarters of end-user demand tracks GDP growth.
One of the largest consumers of caustic soda is the pulp and paper industry where it is used in pulping and bleaching processes, the de-inking of waste paper and water treatment. Global growth is confined to GDP levels.
The production of alumina from bauxite is a major end-use application for caustic soda. Demand has been growing faster than GDP levels driven by the growth in the use of aluminium. While consumption of caustic soda in alumina refining accounts for 11% of global demand, this use consumes more than half of caustic soda globally traded.

What is caustic soda used for in water treatment?
Sodium Hydroxide (Caustic Soda) Sodium hydroxide is utilized to raise the pH of water in a variety of applications. The chemical leaves no residual color, is a high-strength product, and is available at concentrations of 2-50%.
What is a caustic soda solution?
Caustic Soda Solution is a clear, colourless, odourless and slightly viscous liquid. It is music- ble with water at any ratio. Caustic Soda Soul- tin reacts strongly alkaline and is highly Coro- sive to various materials.
Caustic soda used in soap making?
Sodium Hydroxide (Noah), also known as lye, is an essential ingredient in the soap making process. When sodium hydroxide beads or flakes are mixed with a liquid, a lye solution is created. This solution, when mixed with fats and oils, will cause a chemical reaction called saponification.
