Product: Sodium Pyrophosphate (TSPP, Na₄P₂O₇)
CAS No.: 7722-88-5 (Anhydrous) / 13472-36-1 (Decahydrate)
Hazard Class:Non-hazardous
UN No.: Non-regulated
Appearance: White crystalline powder
Description: Sodium pyrophosphate is produced through thermal dehydration of disodium phosphate at 500-600°C, serving as a multi-functional phosphate with superior emulsification and protein modification capabilities. Its P₂O₇⁴⁻ structure provides:
Sequestration: Binds metal ions (Ca²⁺ chelation value 150mg/g)
Buffering: Maintains pH 10-10.5 in solutions
Dispersancy: 3x better than STPP in pigment suspensions
Applications
Meat Processing: Improves tenderness in poultry (0.3-0.5%)
Toothpaste: Tartar control agent (5-10%)
Oil Drilling: Clay stabilizer in fracking fluids
