Chemical Description

  • Sodium Trimetaphosphate is a chemical compound that is whitish and has a molecular formula Na3P3O9.
  • It is an inorganic compound, a salt consisting of sodium and trimetaphosphate.
  • Sodium Trimetaphosphate is produced industrially by heating sodium dihydrogen phosphate at 550℃.
  • In the food industry, it is used as a starch modifier, juice turbidity inhibitor, meat binding agent, dispersant, and stabilizer (for ice cream, cheese, etc.).
  • It can prevent food from discoloring and also prevents the decomposition of vitamin C.
  • It helps to improve the texture and water retention in processed meat and seafood, keeping the food fresh for consumption.
  • STMP is used in the industrial application of water treatment and as a water softener.
  • In water treatment plants, it prevents the deposition of scale and prevents corrosion.
  • It is soluble in water and used as an agent in detergent and cleaning chemical production.
  • It has a widespread application in industrial processes like textile processing, metal surface treatment, and ceramics manufacturing as buffering agents and sequestration.
  • It is used in many personal care products, especially in toothpaste.
  • In pharmaceuticals, it acts as a buffering agent in many reactions and controls the pH of different products.
  • Sodium Trimetaphosphate is an agriculture, industrial, electron, and food-grade chemical, with a major use as a food additive.
  • It works as a crosslinking agent in the crosslinked amylase-resistant starch.
  • It is used as a buffering agent in photographic development, as a hardening agent in photographic emulsion, and as an anti fogging agent in photographic processing.
  • Its major functions are separating water hardness, pH buffering, dirt emulsification, sedimentation prevention, oil hydrolysis, and dirt particle dissolution.
  • 99% pure sodium trimetaphosphate is available in 25 Kg bag packaging.
  • It can be stored at 20-25℃ in closed, light-resistant, dry, and cool places.
  • It is a hazard-free, food-grade chemical, not for direct consumption.
