Tetrasodium pyrophosphate

Tetrasodium pyrophosphate ( CAS 7722-88-5 ), commonly known as TSPP or designated E450(iii) in food applications, is an inorganic phosphate salt used across food processing, industrial cleaning, and construction sectors. It functions primarily as a sequestrant, buffering agent, and dispersant, controlling metal ions and pH in complex formulations. In food manufacturing, TSPP acts as an emulsifying salt in processed cheese. It also serves as a moisture-retention agent in seafood and meat products. Detergent and industrial cleaning formulators use it to sequester calcium and magnesium ions, preventing scale buildup and improving surfactant performance. In hard-water conditions, it enhances cleaning efficiency. In cement and construction materials, it serves as a dispersant and set retarder, improving workability of cementitious mixes during the application process. Water treatment operations apply TSPP to control metal ion precipitation and inhibit scale formation in process water systems. This ensures the longevity and efficiency of industrial piping and equipment. Tetrasodium pyrophosphate is supplied as a white anhydrous powder or granules. Standard grades include food-grade ( FCC compliant) and technical-grade for various industrial applications and manufacturing needs. Buyers sourcing for food or regulated end uses should confirm compliance with relevant regional food additive specifications. This ensures the material meets the necessary safety and quality requirements for the market. Contact us for supply of Tetrasodium pyrophosphate Request Quote
