Hydroxylapatite is a natural mineralization of calcium apatite (Ca5(PO4)3(OH)), and one is chemically synthesized. Hydroxylapatite powder is mostly used in bone substitute materials, and has good biocompatibility and affinity.

Applications of Hydroxyapatite Powder

Hydroxyapatite Powder is extensively used in the dental, orthopedic, pharmaceutical, and cosmetic sectors. In oral care, it is formulated into toothpastes, mouthwashes, and whitening products to help restore enamel, reduce sensitivity, and promote oral health. In the biomedical field, it serves as a component in bone grafts, coatings for implants, and bone tissue engineering due to its natural compatibility with bone mineral.

Cosmetic applications include use in mineral-based skincare and anti-aging formulations, where it contributes to cellular repair and collagen support. It is also a functional ingredient in nutritional supplements aimed at supporting bone density, joint health, and calcium absorption.
