ECHEMI Editorial Reference

Sodium tripolyphosphate (STPP) is a white powder, soluble in water, its water solution is alkaline. It is a crystalline inorganic salt that can exist in two anhydrous crystalline forms (phase I and phase II) or a hydrous form (Na5P3O10 . 6H2O). STPP is used in a large variety of household cleaning products, mainly as a builder, but also in human foodstuffs, animal feeds, industrial cleaning processes and ceramics manufacture. white or colourless crystals, granules or powder
