Description:
Sodium Tripolyphosphate (STTP), also called Sodium Tripolyphosphate (STPP), is an inorganic compound with the formula Na₅P₃O₁₀. It is a white crystalline powder widely used in various industrial applications due to its excellent chelating, dispersing, and water-softening properties. STTP is commonly produced by heating a mix of disodium phosphate and monosodium phosphate and is highly soluble in water.
