Sodium Tripolyphosphate Powder Applications 

-In detergents.

In hard water, detergents are deactivated. Being a highly charged chelating agent, TPP5−binds to dications tightly and prevents them from interfering with the sulfonate detergent.

-Food applications

STPP is a preservative for seafood, meats, poultry, and animal feeds. In foods, STPP is used as an emulsifier and to retain moisture. Many governments regulate the quantities allowed in foods, as it can substantially increase the sale weight of seafood in particular.

-Other uses

Ceramics (decrease the viscosity of glazes up to a certain limit);

Leather tanning (as a masking agent and synthetic tanning agent - SYNTAN);

Anticaking agents, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze, etc.
