Sodium pyrophosphate decahydrate

Sodium pyrophosphate decahydrate (CAS 13472-36-1 ), commonly abbreviated as TSPP, is the fully hydrated crystalline form of tetrasodium pyrophosphate. It functions as a chelating agent, pH buffer, and dispersant across a broad range of industrial and food-grade applications. Procurement teams sourcing TSPP in hydrated form should note that water content affects active concentration relative to the anhydrous grade. In food processing, TSPP acts as an emulsifying and sequestering salt in processed cheese, seafood, and cured meat products. It is essential for controlling texture and preventing discoloration by binding metal ions. Water treatment operations use it to sequester calcium and magnesium hardness, preventing scale formation in boilers and distribution systems. In textile and leather processing, it disperses dyes and assists in removing metal impurities during preparation stages. Personal care formulators incorporate it as a pH buffer and tartar-control agent in oral care products, particularly toothpaste. Sodium pyrophosphate decahydrate is supplied as white crystalline granules or powder. It is available in food-grade specifications meeting FCC and technical-grade standards for industrial use. Packaging typically ranges from 25 kg bags to bulk quantities, with purity specifications commonly at 99% or higher on a dry basis. This ensures consistent performance across various manufacturing and chemical processing environments. Contact us for supply of Sodium pyrophosphate decahydrate Request Quote
