Chemical Description

  • Sodium Pyrophosphate is an inorganic compound and a white crystalline powder.
  • It is a non-toxic and biocompatible compound used as an electroactive media for exfoliation of the surface coating.
  • TSPP is used as an additive in the food industry and has many other applications.
  • It is used as a leavening agent in baking powders. It helps to improve the texture and rising properties of the dough, making perfectly baked cookies, bread, and buns.
  • It is a water-binding agent in processed meat. It retains moisture in the meat, keeping it juicy and tender.
  • It also helps preserve food products and extend the shelf life of processed meat.
  • It is added as an emulsifier in food products to improve their texture and stability.
  • It also helps to prevent the separation of ingredients in many food products, such as sauces and salad dressings.
  • TSPP is widely used in food and beverages as a buffering agent to regulate the pH and acidity of products.
  • It is used in some pharmaceutical products or formulations as a buffering agent or stabilizer.
  • It can be used as an inorganic additive to improve the stability and electrochemical performance of redox flow batteries.
  • It is a stable compound when stored at ambient temperature, and it is incompatible with strong oxidizing agents.
  • It is soluble in water but insoluble in alcohol and ammonia.
  • Sodium pyrophosphate is used in many industrial and household cleaning products as a softener or detergent builder.
  • It enhances the overall working of the detergents by preventing the precipitation of mineral salts in hard water.
  • It also has industrial applications such as meta-cleaning, water treatment, and metal finishing.
  • This food-grade material is available in 25 Kg bags.
  • It is a stable compound at ambient temperature and should be stored in a cool, dry, and well-ventilated place away from heat.
