Description
Sodium Hydroxide Product Overview
Sodium hydroxide (NaOH) is a white, highly hygroscopic solid supplied as flakes, pearls (prills) or 50% aqueous solution, with a purity of 98–99.5% for solids. It also dissolves in water with strong heat release and forms a very strongly alkaline solution.
In addition, pulp and paper mills use caustic soda for cooking and bleaching, and alumina refineries use it in the Bayer process. Similarly, soap and detergent producers use it to saponify fats, textile producers use it for mercerizing cotton, and water treatment plants use it for pH adjustment. It is also a key reagent in organic and inorganic chemical production, in biodiesel catalysis and, in food grade, as E524.
Furthermore, related alkalis and salts in our range include Sodium Bicarbonate, Potassium Carbonate and Lithium hydroxide.
Key Applications of Sodium Hydroxide

⚠️ Safety & Handling: Causes severe skin burns and eye damage; dissolving it in water releases much heat. Always add it slowly to water, never water to it, and also wear chemical-resistant gloves, face protection and protective clothing. Store in tightly closed containers in a dry place, away from acids and aluminium. Always consult the Safety Data Sheet (SDS), because it contains the full classification and handling instructions.
