Sodium Hydroxide (Caustic Soda) Solution | 25% & 50% | NSF®-60 Certified Sodium Hydroxide (Caustic Soda) is an essential chemical used across municipal, industrial, and food-related applications. Available in 25% and 50% liquid solutions, this versatile product is supplied in 304 kg drums, 171 kg small drums, and 30 kg carboys to suit operations of any size. In municipal water treatment, sodium hydroxide is used to control water acidity (pH adjustment) and remove heavy metals such as lead, copper, and zinc. It is also a key raw material in the production of sodium hypochlorite, a powerful and widely used water disinfectant. Beyond water treatment, caustic soda is an industry standard for chemical manufacturing, pulp and paper processing, textiles, cleaning products, and food processing applications. Both concentrations are NSF/ANSI Standard 60 certified, making them safe for drinking water applications. They are also Kosher and Halal certified, with Canadian Food Inspection Agency approval for regulated establishments when used according to label directions.
