Sodium tripolyphosphate CAS No 7758-29-4
White granular or powder form, with a bulk density of 0.35–0.95 g/cm³ and a melting point of 622℃. It is readily soluble in water, and its aqueous solution is alkaline. It hydrolyzes gradually into orthophosphate in water and has a good ability to complex with metal ions. It can complex with metal ions such as calcium, magnesium and iron to form soluble complexes and is capable of softening hard water. As an inorganic surfactant, it exhibits certain properties of organic surfactants.
