From the water you drink, the soap and detergents you use, and the clothes you wear, caustic soda is present in almost every part of your home. Also known as Sodium hydroxide (NaOH), caustic soda is one of the very few chemicals with a broad range of applications. It is commonly used in homes as an agent for unblocking drains, either in the form of dry crystal or as a thick liquid gel.
Caustic soda has a wide variety of industrial applications, such as in the manufacture of pulp and paper, textiles, bio diesel, soaps and detergents. And likewise, in water softening and treatment, refining petroleum products, in food preparation in the form of lye and washing beer and soft drink bottles. Caustic soda is the most common base used in chemical laboratories as cleaning-in-place (CIP) chemicals. Some popular food uses include chocolate and cocoa processing, caramel color production and poultry scalding.
