Caustic soda (also known as sodium hydroxide, lye or NaOH) is a solid white product supplied as flakes. It is a highly caustic base and alkali, and in contact with the skin it can cause severe burns. It is a versatile product used in a wide variety of processes.
Sodium hydroxide is used in many industries: in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents, and as a drain cleaner. It is one of the most widely used chemicals in the world.
