Sodium Hydroxide, also known as lye or caustic soda, is a highly caustic metallic base and alkali salt. Available in pellets, flakes, and solution forms, this compound is widely recognized for its powerful cleaning capabilities and is essential across countless industrial applications.
Uses: Found in many household and commercial cleaning products, especially drain openers and oven cleaners, where it breaks down grease and organic blockages. Also used in soap making to saponify oils and fats.
Industrial Applications: Vital in pulp and paper production, sodium hydroxide is used to process wood into paper. In textiles, it is used for fiber treatment and dyeing. It's also an important pH adjuster in water treatment facilities and acts as a catalyst in biodiesel production.
Safety and Handling: Due to its corrosive nature, proper PPE is required—including gloves, safety goggles, and chemical-resistant clothing. Always store in a dry, well-ventilated space away from acids and organic compounds. If contact occurs with skin or eyes, flush immediately with water and seek medical attention if irritation persists.
