Excipients: Calcium phosphates

Together with Canberra Chemicals, Alsiano offers a line of calcium phosphates at competitive prices

Canberra Chemicals, founded in 1975, is an India-based manufacturer of calcium phosphates with manufacturing facilities that comprise state-of-the-art equipment and a fully equipped laboratory operated by a highly skilled staff.

Canberra manufactures the following types of calcium salts of phosphoric acid:
•    Dibasic calcium phosphate dihydrate/anhydrous
•    Tribasic calcium phosphate

Dibasic calcium phosphate
The unmilled granules of dibasic calcium phosphate have excellent flow properties and an ideal compressibility index with a nearly 70% retention at 100 ASTM and fines below 5% at 325 ASTM. This makes it ideal for direct compression tableting formulations. For applications exceeding 45°C, the anhydrous form is preferred.

Tribasic calcium phosphate
This is a bulky powder with an ideal Ca/P ratio of 2:1 for better bio-availability in calcium supplements. The crystalline powder is manufactured by a special process that gives it high porosity. This high porosity makes it ideal for application as an anticaking agent.

All Canberra phosphates conform to California Proposition 65 regarding lead and fluorine levels. It is also worth mentioning that for direct compression into tablets, Canberra can offer calcium phosphates with specific particle sizes tailored to the customer’s need.

Applications
Canberra calcium phosphates are sold to pharmaceutical companies in India, USA, Western Europe, and other markets. The main scope of application includes:
