Sodium Tripolyphosphate (Food Grade, Kosher)


Sodium tripolyphosphate, also known as sodium triphosphate or STPP, is mainly consumed as a component of commercial detergents. It serves as a builder or water softener, particularly in hard water containing high concentrations of magnesium and calcium ions. In such conditions, detergents can be deactivated. However, STPP, being a highly charged chelating agent, tightly binds to calcium and magnesium ions, preventing their interference with sulfonate detergent performance.

STPP is not only used in detergents but also serves as a preservative for seafood, meats, poultry, and animal feeds. In the food industry, it is commonly known as E451 and finds usage as an emulsifier and moisture retainer. Many governments regulate the quantities allowed in foods, as STPP can substantially increase the sale weight of seafood. The United States Food and Drug Administration recognizes STPP as "generally recognized as safe."

Sodium tripolyphosphate is available in low density, medium density, and high-density granular powders. The specific product being described here is a medium density variant. It is categorized as food (FCC) grade, granular, medium density, and Kosher-certified. Besides its primary uses in water softening and as a sequestering agent, STPP can also function as a peptizing or deflocculating agent. Furthermore, it has applications in detergents, soaps, and ceramics.

The chemical structure of sodium tripolyphosphate is [Na5P3O10]n. It is also known by synonyms such as sodium triphosphate, triphosphoric acid pentasodium salt, sodium phosphate tripoly, STPP, pentasodium triphosphate, and pentasodium tripolyphosphate. The product is packaged in 50-lb bags by the original manufacturer, while smaller quantities are repacked for laboratory, research, and industrial uses. The CAS number for sodium tripolyphosphate is [7758-29-4][Na5O10P3]n.

Sodium tripolyphosphate exhibits low toxicity, making it a safe choice for various applications.


Key Features:

  • Effective detergent component and water softener
  • Chelating agent that prevents interference with sulfonate detergents
  • Preservative for seafood, meats, poultry, and animal feeds
  • Emulsifier and moisture retainer in food production
  • Regulatory compliance and recognized as safe by FDA
