What is Sodium Tripolyphosphate (STPP)?

Sodium tripolyphosphate (chemical formula: Na₅P₃O₁₀) is a white, crystalline or granular powder widely used as a builder, sequestrant, emulsifier, and stabilizer in various industrial processes. As a multipurpose inorganic compound, STPP enhances cleaning efficiency, improves water softening, disperses dirt and soil, and stabilizes chemical formulations.

STPP is a key raw material in detergents, ceramic manufacturing, leather processing, water treatment, oil drilling, and food-grade applications. With excellent chelating and sequestration properties, sodium tripolyphosphate improves cleaning power, prevents scale formation, enhances product stability, and supports efficient industrial operations.

At Sri Varahi Chemicals, we manufacture and supply high-purity STPP with controlled moisture content, accurate particle size, and consistent chemical composition tailored to industrial requirements.
