Liquid sodium hydroxide (Caustic Soda) is a colorless, odorless liquid, produced in 50% and 32% purity, and highly corrosive at all concentrations.

Liquid Sodium Hydroxide is soluble in water and equal proportions such as Ethanol, Methanol and Glycerin. The freezing point of this material is 4.4 and the boiling point is 145 °C.


Sodium hydroxide is used in the aluminum industry to dissolve bauxite ore, the raw material for aluminum production, it is also used in pup and paper bleaching processes, chemicals, soaps, food and healthcare industries.


Caustic Soda Liquid Reactivity:


Caustic Soda Liquid is a highly reactive material which reacts rapidly with carbon dioxide. Although it is stable chemical, it start chemical reaction due to temperature changes. The heat causes the product to become unstable and reactions to start and in case of severe heat shock, it can cause explosion. Liquid Caustic Soda is highly corrosive and reacts easily with metals such as Aluminum, Magnesium, Zinc, Chromium, Bronze, Copper and Brass. Galvanized surfaces react rapidly in direct contact with caustic soda solution. As a result of the corrosion process of these metals, Hydrogen gas is released, which can cause explosion. If the temperature drops below 18 ° C, the viscosity of the liquid soda increases dramatically.

Although Liquid Caustic Soda is not flammable or explosive on its own, it can react with various acids such as Hydrochloric Acid to neutralize and release significant heat. It affects human and animal tissues such as leather, skin and eyes. Liquid Sodium hydroxide also easily reacts with Fructose, Galactose, Maltose, and produces Carbon Monoxide.

Safety tips

Storage life of Liquid Caustic Soda depends on storage conditions. Exposure to air will affect the quality of the product. Because liquid absorbs Carbon Dioxide from the air and then solid Sodium Carbonate particles are formed.

Another factor influencing storage life of this product is storage tanks. If the linings of these tanks are damaged and the Liquid Caustic Soda comes in contact with the steel and starts chemical reactions. Therefore, contact with air or metals can affect the quality and shelf life of Sodium Hydroxide storage.
