Product Introduction:

Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP) is an inorganic compound. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespread use.


Sodium tripolyphosphate has functions such as chelation, suspension, dispersion, gelation, emulsification, and pH buffering. It can be used as a main auxiliary for synthetic detergents, industrial water softeners, tanning pre tanning agents, dyeing aids, organic synthesis catalysts, pharmaceutical industry dispersants, and food additives.
