Product Description

Product Description

Sodium Tripolyphosphate (STPP) 

Sodium Tripolyphosphate (STPP) is a white crystalline powder or granular material, widely used as a water softener, detergent builder, and dispersing agent. It effectively prevents the deposition of calcium and magnesium ions in hard water, improving cleaning efficiency in detergents and household cleaners. In the food industry, it serves as a preservative, emulsifier, and moisture retention agent for seafood and meat products. STPP is also used in ceramics, water treatment, and leather processing due to its excellent chelating and dispersing properties.
