Food Additive STPP Mono Sodium Phosphate Anhydrous Tripolyphosphate White Powder
Sodium Tripolyphosphate (STPP, Na₅P₃O₁₀) is an inorganic compound widely used in industrial and commercial applications including detergents, water treatment, ceramics, and food processing. This white crystalline powder features high water solubility and excellent dispersing, buffering, and sequestering properties. Its effectiveness in breaking down dirt, stains, and scale deposits makes it essential for cleaning agents and water-softening formulations.

Manufactured through controlled heating of phosphoric acid and sodium carbonate, followed by polymerization, purification, and crystallization processes. This ensures consistent high quality for diverse industrial applications.
In aqueous solutions, STPP dissociates into sodium (Na⁺) and tripolyphosphate ions (P₃O₁₀⁵⁻), which bind metal ions to prevent scale formation. This mechanism enables effective water softening, particle dispersion, and pH stabilization.
