Cas no 13472-36-1 (Sodium pyrophosphate decahydrate)

Sodium pyrophosphate decahydrate (Na?P?O?·10H?O) is a hydrated form of tetrasodium pyrophosphate, commonly used as a buffering agent, emulsifier, and dispersant in industrial and food applications. Its high solubility in water and stable pyrophosphate anion make it effective for sequestering metal ions, preventing oxidation, and stabilizing pH levels. In food processing, it acts as a leavening agent and improves texture in baked goods and processed meats. Industrially, it serves as a detergent builder and in water treatment for scale inhibition. The decahydrate form ensures consistent handling and dissolution properties, making it suitable for precise formulations requiring controlled phosphate release.
