Usuage

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.

Food additives

The uses of STPP also include using it as a preservative. It can be used to preserve foods such as red meats, poultry, and
seafood, helping them to retain their tenderness and moisture. Pet food and animal feed have been known to be treated with STPP,
serving the same general purpose as it does in human food. STPP also has been used in helping to preserve the quality of drinks
such as milk and fruit juices.

Other uses

As a builder, sodium tripolyphosphate mainly is used in detergents and soaps. This includes dishwasher detergents as well as laundry detergents. It is used in most gel, liquid, tablet, and powder forms of each type of detergent. In the detergent, it helps strengthen the cleaning action.
It is used in paint as a pigment dispersant. Ceramics use it to help disperse clay, and paper mills use it as an oil-resistant agent when coating paper. It additionally has been used as a tanning agent in making leather, and the minerals in cement have been
known to be treated with it. Sodium tripolyphosphate also has been used as an additive in toothpaste due to its cleaning action.
