SODIUM TRIPOLYPHOSPHATE (STPP) - LIGHT DENSITY
A Versatile Phosphate Ingredient for Detergent Manufacturing and Industrial Processing
Sodium Tripolyphosphate (STPP) – Light Density is an inorganic phosphate compound widely used in detergent manufacturing and various industrial applications. Typically supplied as a white powder or granular solid, it is valued for its ability to bind hardness ions, support water softening, and disperse particles in aqueous systems. In detergent formulations, STPP helps improve cleaning efficiency by managing mineral ions that can interfere with surfactant performance. Its sequestration and dispersing properties also make it useful in ceramics, water treatment, and other industrial processes. The light-density grade is particularly relevant to detergent formulations where bulk density and powder characteristics are important considerations.
