Description

Hydroxyapatite is a naturally occurring mineral form of calcium apatite and the primary inorganic component of bone and dental enamel. This high-purity synthetic grade offers exceptional biocompatibility and bioactivity, making it a critical material for advanced medical and life science applications. It is essential for manufacturers in the orthopedic, dental, pharmaceutical, and chromatography sectors seeking reliable, high-performance biomaterials.

Application

• Bone Graft Substitutes & Orthopedic Implants: Used as a bioactive coating on metallic implants or as a porous scaffold to promote osteointegration and bone regeneration.
• Dental Care & Restorations: A key component in toothpaste for remineralization, as well as in cements, composites, and coatings for dental implants.
• Chromatography Media: Serves as a robust stationary phase for the purification of proteins, antibodies, and nucleic acids due to its unique interaction properties.
• Drug Delivery Systems: Utilized as a biodegradable carrier for the controlled release of therapeutic agents in targeted treatments.
• Cosmetics & Personal Care: Incorporated as a gentle abrasive in exfoliants and a biomimetic ingredient in anti-aging skincare formulations.
• Biomedical Research: Employed as a standard substrate in cell culture studies to investigate cell-material interactions and bone tissue engineering.

Quality Control

Our Hydroxyapatite is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for purity, crystallinity, particle size, and specific surface area. Certificates of Analysis (COA) detailing these parameters are provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption.
