Product Description
Tetrasodium Pyrophosphate (TSPP) E450 CAS 7722-88-5
Tetrasodium Pyrophosphate is an inorganic compound with the chemical formula Na₄P₂O₇. It appears as a white crystalline powder that readily absorbs moisture from the air, leading to deliquescence. TSPP is soluble in water but insoluble in ethanol and other organic solvents, and exhibits strong complexing ability with metal ions such as Cu²⁺, Fe³⁺, and Mn²⁺.
Key Benefits
- Strong complexing agent for metal ions
- High solubility in water
- Stable in aqueous solutions below 70°C
- Versatile industrial applications
Target Industries & Applications
Commonly used in detergents, water treatment, food processing, and as a dispersing agent.
