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

Water Soluble Starch
This starch is modified so that it can dissolve in water easily and at high concentration. It is used to make laundry starch and starch-based glues such as those used on the back of the stamps. Starch-based glues are highly demanded due to their safety when handled by children. They are also easily washable if they spill on the floor or on clothing. For many years, starch-based glues have been the only or predominant type of glue used at homes and offices. This trend changed after the invention of polymers such as white glue (Polyvinyl acetate). Starch-based glues can also be mixed with pigments to make watercolors.
