Description
Product Description
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.
