Applications This product is widely used across numerous industries, including soap and detergent production, water and wastewater treatment, pulp and paper processing, textile manufacturing, general chemical production, petroleum refining, approved food-grade processing applications, metal degreasing and cleaning, drain-clearing formulations, biodiesel manufacturing, industrial pH regulation, and alumina refining and surface treatment processes.

Storage Guidelines Keep the product in tightly sealed containers made from corrosion-resistant materials, stored in a cool, dry, and properly ventilated space. Avoid exposure to moisture, acids, aluminum, organic substances, and other incompatible materials. Shield containers from humidity and direct sunlight at all times. Secondary containment measures should be used where appropriate, and all containers must be clearly labeled in line with recognized chemical safety guidelines.

Safety & Handling Information (SDS Overview) This is a highly corrosive substance capable of causing severe skin and eye burns. Protective equipment — including chemical-resistant gloves, safety goggles, a face shield, and protective clothing — must be worn at all times when handling this product. Avoid breathing in dust particles and prevent any skin or eye contact. When mixing, always add the flakes gradually into water; never pour water into the caustic soda, as this can trigger a violent, splashing reaction.
