Frequently Asked Questions (FAQs)

Q: What is Calcium Stearate made from?

A: Calcium Stearate is produced by reacting stearic acid (typically from vegetable or animal fats) with calcium hydroxide or oxide. The result is a metallic soap that is non-toxic and widely used in industrial applications.

Q: Is Calcium Stearate safe for use in food and pharmaceuticals?

A: Yes, food-grade Calcium Stearate is recognized as Generally Recognized as Safe (GRAS) by the FDA. In pharmaceuticals, it complies with USP and EP monographs, ensuring it's suitable for human consumption when used appropriately.

Q: What are the storage recommendations for Calcium Stearate?

A: Store in a cool, dry place away from direct sunlight and moisture. Keep containers tightly sealed to prevent contamination. Ideal storage temperature is below 30°C.

Q: How does Calcium Stearate compare to other stearates like Magnesium Stearate?

A: Calcium Stearate offers better thermal stability and hydrophobicity than Magnesium Stearate, making it preferable for high-temperature processes. However, Magnesium Stearate is often chosen for its superior lubricating properties in certain tablet formulations.

Q: Is Calcium Stearate environmentally friendly?

A: Yes, it is biodegradable and does not persist in the environment. Our production processes minimize waste, aligning with sustainable practices.
