Description

Calcium Phosphate Dibasic Dihydrate is a high-purity inorganic salt widely used as a critical functional ingredient. Its primary value lies in its role as a highly bioavailable calcium and phosphorus source, essential for nutritional fortification and as a pharmaceutical excipient. This compound is indispensable for manufacturers in the food & beverage, pharmaceutical, nutraceutical, and animal feed industries seeking a reliable, compliant, and consistent raw material.

Application

• Pharmaceutical Tableting: Acts as a diluent and calcium source in solid dosage forms like tablets and capsules.
• Food & Beverage Fortification: Used to enrich products such as breakfast cereals, flour, beverages, and dairy alternatives with calcium and phosphorus.
• Nutraceutical & Dietary Supplements: A key active ingredient in calcium supplement formulations due to its favorable bioavailability.
• Animal Feed Premix: An essential mineral supplement for livestock, poultry, and pet food to support bone health and development.
• Dentifrice Applications: Employed as a mild abrasive and calcium source in certain toothpaste formulations.
• Bioceramics & Bone Graft Materials: Serves as a precursor in the synthesis of calcium phosphate-based biomaterials for medical implants.
