Sodium Tripolyphosphate (STPP) About

Sodium Tripolyphosphate (STPP) is a high-quality inorganic phosphate chemical widely used in industrial, detergent, water treatment, ceramic, textile, and food processing applications. It is a white, free-flowing crystalline powder or granular material with excellent water solubility and strong sequestration, dispersing, and buffering properties. STPP effectively softens hard water by binding calcium and magnesium ions, improving the performance of detergents and cleaning formulations. It is also used as a dispersing agent, emulsifier, stabilizer, and pH regulator in various manufacturing processes. Available in industrial, technical, and food grades, Sodium Tripolyphosphate offers high purity, consistent quality, and reliable performance, making it an essential raw material for a wide range of commercial and industrial applications.
