Sodium Hydroxide Pellets BP

Back to Excipients Page

Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations and hydroxide anions. Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air.

Sodium hydroxide is used in many industries, particularly in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents, and as a drain cleaner as well.
