Sodium Tripolyphosphate - Versatile Detergent Component and Food Preservative
Sodium Tripolyphosphate, Food grade, Kosher (STPP_M)

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

What is a Steam Trap?
A steam trap is a device used in steam systems (mainly heating and ventilation systems) to reduce condensation and gasses while retaining the most steam possible. Many steam traps serve as automatic valves and open, close or modulate automatically. Other are turbulent two-phase flows that obstruct the flow of steam. In many industries, steam is used regularly for heating or as a driving force for mechanical power. Steam traps are used in such applications to ensure that steam is not wasted. Steam traps are particularly useful when determining the heat of vaporization with a steam calorimeter. This model below consists of a borosilicate glass chamber with a curved inner tube to prevent drops of condensed steam from escaping, as well as a drainage tube.

Uses for Steam Traps?
Air Ventilation: A steam trap can help your heater work more efficiently and warm up faster. When a heater turns on, the space is filled with air, which will reduce heat transfer causing an increase in warm-up time. Using a steam trap, you can purge air from the ventilation system as it mixes with steam allowing you to vent the air and keep the condensed steam running through the ventilation system. A float trap with a thermostatic air vent is especially useful because it's programmed to be fully open at start up. 

Condensation Removal: Once air is vented from the system, the trap must pass the condensate from the system, but not allow the steam to escape. Retaining the maximum amount of steam in the system allows the heat exchange to run at its most efficient and economical. If necessary, the trap allows for the condensate to be discharged immediately to maintain proper heat transfer. 
Plant Performance: In order for a heat exchanger to operate to its full performance, the steam space must be filled with clean, dry steam. You can use different types of steam traps to influence this. Thermostatic traps retain the condensate until its cooled below the temperature of saturation. Discharging the condensate at the lowest possible temperature may seem attractive, but the condensation could end up water-logging the system. Water-logging is the main source of inefficiency and corrosion in a steam system. The right steam trap will allow you to avoid this problem while ensuring your system is running at its best.
