STPP is White powder or powder, apparent density 0.35-0.90g/cm3, melting point 622 ºC. soluble in water. The aqueous solution is alkaline, and the pH of 1% aqueous solution is 9.7. It is gradually hydrolyzed into phosphite in water and has a good ability to complex metal ions. It can complex with calcium, magnesium, iron and other metal ions to form soluble complexes. Can soften hard water. As an inorganic surfactant, it has the properties of a certain organic surfactant.

1.A Powerful Cleaning Agent:Sodium tripolyphosphate(Na5P3O10) is a strong cleaning ingredient that typically can rid dishes and fabrics of soil and spots. Its key function is that it allows surfactants to work at their full potential. Also, it prevents deposition of soil and acts as a pH buffer. It softens detergent water and can be used as a water treatment, as well. Many household cleaning products, including surface and toilet cleaners, contain STPP due to its cleaning component. Most chemical plants that make STPP list "detergents" as the primary area of use for this chemical.
