    Product Overview

    Sodium tripolyphosphate STPP is an inorganic compound, also known as pentasodium triphosphate or sodium triphosphate. It appears as a white crystalline powder. STPP is soluble in water, forming alkaline solutions, and also soluble in acids but insoluble in organic solvents. In food processing, STPP is used as an acidity regulator, chelating agent, and preservative. In industrial applications, STPP is utilized as a water treatment chemical, detergent, cleaner, and flame retardant.
