Caustic soda, or sodium hydroxide, is a corrosive substance. It is used in a wide variety of industries, mainly in the production of pulp, paper, soaps, detergents, and textiles. It is also used to unblock drains.

Caustic soda is a strong base, a substance that can accept hydrogen ions, and is in widespread use in the chemical industry. It is used when there is a need to increase the alkalinity of a chemical mixture. It can also neutralise acids, such as carbon dioxide. Crude oil is sometimes treated with caustic soda to remove impurities. This is known as caustic washing, although, due to the toxic waste produced, it is banned in many countries.

Another major use of caustic soda is the making of paper. It is used in a solution that helps to separate lignin from cellulose fibers to make wood pulp. It can also be used to bleach the brown pulp created during the pulping process.
