About Product
Caustic soda lye, also known as sodium hydroxide solution or caustic soda solution, is a liquid form of sodium hydroxide (NaOH) dissolved in water. It appears as a clear, colorless liquid with a slippery texture and strong alkaline nature. Due to its hygroscopic properties, this solution readily absorbs moisture from the air and maintains high chemical reactivity. Industries across the globe rely on caustic soda lye manufacturers and established caustic soda manufacturers for consistent quality, safety, and performance. Available in different concentrations, including industrial grades such as caustic liquid-320, caustic soda lye is widely used in chemical processing, water treatment, textiles, petroleum refining, and manufacturing applications.
