Sodium tripolyphosphate STPP 94%
Product Description
Sodium tripolyphosphate(STPP), also known as pentasodium triphosphate, pentasodium tripolyphosphate or sodium triphosphate, is used in a wide range of applications in the manufacture of cleaning products and food preservatives as well as in water treatment facilities. STPP is a sodium salt of triphosphoric acid that has the appearance of white crystal powder. It is odorless and is water soluble. In a highly controlled environment, it is made by combining monosodium phosphate and disodium phosphate.
