Chemical Description

  • Tricalcium Phosphate is an inorganic white, odorless, tasteless powder with a low solubility in water.
  • Tricalcium phosphate consists of a variable mixture of calcium phosphates obtained from the neutralization of phosphoric acid with calcium hydroxide.
  • Its approximate composition is 10CaO3P2O5H2O, which complies with the specifications of GB25558-2010, FCC, and the EC Regulation for food additives.
  • In the food industry, it is used as a nutritional supplement, Anti-caking agent, pH regulator, buffer, clouding agent, chelating agent, etc.
  • Tricalcium phosphate is commonly used in powdered food products as an anti-caking agent to prevent clumping. It is also used as a calcium supplement in some food items.
  • In pharmaceuticals, TCP has been extensively used as a tablet excipient, providing binding and disintegration properties. It has wide usage in calcium supplements.
  • TCP is used in animal feed due to its rich source of calcium and phosphorus. The feed carrying this chemical is more nutritious and provides better bone health and overall growth of livestock.
  • It has a wide application in industrial processes and is used as a polishing agent and flame retardant additive.
  • It improves soil health and fertility when added to fertilizers.
  • Tricalcium Phosphate is a non-hazardous chemical and is generally recognized as safe (GRAS) by the Food and Drug Administration (FDA).
  • TCP can regulate the pH by releasing calcium and phosphate ions into the solution.
  • It is used as an ingredient in many dental care products like toothpaste and mouthwash. It helps to clean the teeth by removing plaque and surface stains from teeth.
  • It also can resist changes in pH and act as a buffering agent in many chemical reactions.
  • It is used as a pH regulator and a buffering agent in various industries, such as pharmaceuticals, agriculture, food, and beverages.
  • 95% pure TCP is available in 25 Kg Kraft paper or plastic woven bags with a PE inner.
