In detergent
Most of STPP is consumed as a component of commercial detergents. It is used as an industry term for "manufacturers" of water softeners. In hard water (water containing high concentrations of Mg2 + and Ca2 +), the detergent will be inactivated. As a highly charged chelating agent, TPP5- binds firmly to fingerprints and prevents them from interfering with sulfonate detergents.

STPP is a preservative for seafood, meat, poultry and animal feed. The E number E451 is usually used in food production. In food, STPP is used as an emulsifier and retains moisture. Many governments regulate the amount allowed in food because it can greatly increase the weight of seafood sales. The US FDA lists STPP as "generally considered safe."
