What is Sodium Tripolyphosphate?

It’s a mineral composite used by numerous people for multiple causes, generally utilized as the polyphosphate sodium salt, the conjugate triphosphoric acid-base. A stoichiometric combination creates it by exposing disodium phosphate and monosodium phosphate to heat. The procedure gets executed, considering well-ordered circumstances precisely and cautiously.

How it is traded?

Mainly trade of this compound is happening as a white, solid powder by sodium tripolyphosphate suppliers. This mineral composite doesn’t create any fragrance. However, it gives a slightly primary palate once consumed orally. It is stable at room temperature and likewise significantly soluble in the liquid. Sodium tripolyphosphate is usually referred to as STPP; it seems on maximum tags, as you have seen. It is non-combustion and highly noxious. The crucial use of STPP (sodium tripolyphosphate) is as a liquid leveler in multiple cleaner categories.

How Sodium Tripolyphosphate is made?

It assists in confirming that detergents execute fine in salty liquid. This compound’s additional prime use is to reserve numerous nutrition goods, such as animal feeds, seafood, and poultry products. It performs as an emulsifier and preserves moistness in spoilable foodstuff like meat as it’s considered a harmless composite (GRAS) by the FDA and other authorities.

Meanwhile, this substance is constant and much less noxious than other available options. It doesn’t necessitate any superfluous caution or consideration. It necessarily requires to be kept in an equable place, moist free area, and kept wrapped appropriately to not intermingle with anything in the atmosphere. Furthermore, it makes slight touchiness on direct exposure to skin or eyes, and if swallowed in massive amounts, it is quite harmful.

The demand for this product:

The inorganic substance is highly required in mass levels internationally. To understand the significance of this mineral, the requirement for two annuals is given under. Imagine how much in demand sodium tripolyphosphate suppliers were in 2005 and 2006; the Foundation of data is ICIS Chemical Business USITC.

  • 2005: 277,000 tons
  • 2006: 280,000 tons
  • 2010: 285,000 tons.

Demand equals production:

  • More imports (2005 YEAR: 142,000 tons 2006 YEAR: 142,000 tons),
  • Fewer exports (2005 YEAR: 10,000 tons 2006 YEAR: 6,000 tons).

Growth of sodium tripolyphosphate:

The development of the STPP in the 2001-2006 year was 1% per year. Future expansion was 0.5% per year by 2010.

Price of sodium tripolyphosphate:

Amid 2001 and 2006, it was costly, up to $41.40 per cwt. The property-owning tax-payable import rate was less, up to $27.85, a similar base.

Common uses:

  • Cleaner producers utilize approx. 48% (25% industrial and institutional cleaners, 23% dishwashing)

  • Food and beverage, 32% (15% in meat, poultry, seafood, 9% baking, 6% dairy, 3% other)

  • process and boiler water treatment uses 8% of chemical

  • miscellaneous uses 11%, including plastic and metal finishing and dentifrices.

Market viewpoint

In the late 1940s, along with artificial cleaner preparations, STTP or sodium tripolyphosphate arose as the leading high-quality amongst cleaner manufacturer ingredients. Cleaner sodium manufacturers advance the cleaner’s washing characteristics by growing dirt elimination and avoiding or lessening its re-deposition throughout the rinse rotation.

In the late 1960s, the liquid eutrophication difficulties engaged people’s attention to phosphate release from numerous foundations like a primary contributor to the occurrence. It was directed to prohibitions or restrictions on the utilization of phosphate in cleaners in the 1970s.

Diet-grade STPP or sodium tripolyphosphate remains to do reasonably fine with the current treated nutriments development – approx. 1.5% per year. It delivers a diversity of beneficial purposes similar to curing booster, appropriate emulsifier smoothing benefit, or, depending on the use, in preserved nutriments.

Market Tendencies

  • Aggregative usage in maintenance merchandises and make-ups

  • The rising medicinal service sector

  • Developing usages in the agronomic division


It appears that its affected failure in cleaner commerce has ended. Though these still get utilized in detergents - dishwashing powders and organized and manufacturing cleaners.
