Product Description

Tetrasodium Pyrophosphate (TSPP) is a white, free-flowing crystalline powder widely used in the food, detergent, ceramic, and water-treatment industries. As a versatile phosphate salt, TSPP functions primarily as a buffering agent, dispersant, emulsifier, sequestrant, and protein stabilizer.
Its excellent chelating ability for metal ions and its strong alkalinity make it indispensable in both food processing and industrial formulations.
