Tetrasodium Pyrophosphate (TSPP)

Tetrasodium pyrophosphate (TSPP) is an inorganic phosphate salt widely used as a buffering, dispersing, and chelating agent. It is the sodium salt of pyrophosphoric acid and appears as a white crystalline powder, highly soluble in water. TSPP is valued for its ability to sequester metal ions, adjust pH, and improve product stability across multiple industries.

In food applications, TSPP is used as an emulsifier, thickening agent, and water-retention aid, commonly found in seafood, meats, and poultry products to enhance texture and reduce moisture loss. Industrially, it functions as a dispersant in ceramics, detergents, and water treatment formulations. Its sequestering properties also make it useful in preventing scale formation and stabilizing peroxide solutions in cleaning products.

Tetrasodium pyrophosphate is versatile, cost-effective, and highly functional, supporting applications from food processing and detergents to ceramics, textiles, and chemical manufacturing.
