PRODUCT PROFILE: Sodium triphosphate (STP) is an inorganic compound with formula Na5P3O10. It is the sodiumsalt of the polyphosphate penta anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespread use. Product characteristics â€¢ CAS No : 7758-29-4 â€¢ Molecular formula : Na5P3O10 â€¢ Appearance : White free flowing slightly hygroscopic granule or powder. â€¢ Form :Hydrated form and anhydrous form â€¢ Solubility in Water : 20% at 25 deg C â€¢ pH(1% solution) : 9.2-10.2 â€¢ Moisture (at 110 Â°C) : 0.50% â€¢ Water insolubles : 0.07% â€¢ Purity :94.0% â€¢ PH Value : 9.5-10.0 â€¢ Whiteness : 85% min. It has got salient chelating capacity to ions of Ca and Mg etc. and can soften hard water to make suspension solution become into clear solution; It has got weak alkalinity but no corrosiveness. It is a surfactant, and has got outstanding emulsification to lubricants and fat. This product has two crystalline forms, namely Type I (high temperature type) and Type II (low temperature type). The chemical properties of the two types are the same, and the difference between them lies in the thermo stability, hygroscopicity, solubility and hydration heat when dissolving. Applications of Sodium triphosphate (STP): Some of the applications of STPP are: â€¢ Used as one of the main auxiliaries for synthetic detergent, synergist for soap â€¢ water softener, tanning agent for leather making, auxiliary for dyeing â€¢ As an effective dispersion agent for suspension solutions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc. â€¢ As an oil contamination resistance agent in paper production. â€¢ In foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. â€¢ It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. â€¢ It may also serves as a softener or densifier in foodstuff industry. â€¢ Improves the water holding capacity of meat and seafood products â€¢ Prevents denaturation of proteins â€¢ Stabilizes the colour of the products â€¢ Improves the texture of meat and seafood products Food grade STPP is used as quality improver in the process of canned food, fruit juice beverages, foodstuffs from milk or soyabean and is also used as softener or densifier in food stuff industry. GLOBAL SCENARIO: Sodium Tripolyphosphate (STPP) is an inorganic sodium salt, which is used as a vital auxiliary in synthetic detergents sector. For several years, sodium tripolyphosphate has been used as a major ingredient in detergents, and played a vital role in enhancing the performance of detergents. The market for STPP is expected to benefit from the fact that phosphorus-free assistants are not a complete substitute for phosphorus-based assistants. In India, STPP predominantly finds application in the production of detergents. The other important areas of applications include ceramics and food industries. The application areas are highly relevant to the industrial and economic growth pattern. Therefore, the demand for STPP would go up in tune with the overall industrial and economic growth pattern. The global Sodium Tripolyphosphate market is projected to reach 3.4 million metric tons by the year 2015. Growth in the market is driven by the sustained demand from detergents market.
