What does microcrystalline mean for this hydroxyapatite?

The term microcrystalline describes the crystal form and physical structure rather than a separate chemical identity. Crystal size, particle-size distribution, specific surface area, and crystallinity can all influence how the powder behaves in an oral-care, cosmetic, or specialty formulation.

Where is Calcium Microcrystalline Hydroxyapatite mainly used?

It is used in oral-care formulations, cosmetic powders, nutritional or specialty calcium-phosphate programs, biomedical or research applications, and specialty powder systems. The suitable grade depends on particle profile, purity, and the intended formulation.

Which specifications should be checked before ordering?

Confirm appearance, hydroxyapatite content or calcium-to-phosphorus ratio, particle-size distribution, specific surface area, crystallinity, heavy metals, loss on drying, and microbial limits if required. The Ca/P ratio and powder profile should be matched to the final application.

How should Calcium Microcrystalline Hydroxyapatite be stored and handled?

Store it in tightly closed, moisture-protective containers in a cool, dry, well-ventilated area. Avoid dust formation and direct skin or eye contact, use suitable PPE, and confirm the offered package size, net weight, lot traceability, and transport requirements before dispatch.

Calcium Microcrystalline Hydroxyapatite CAS 1306-06-5

Calcium Microcrystalline Hydroxyapatite is an inorganic calcium phosphate material corresponding to hydroxyapatite chemistry. We supply this product for applications where hydroxyapatite is selected according to particle characteristics, purity profile, formulation compatibility, and end-use requirements. Because “microcrystalline” usually refers to crystal form and material structure, the applicable grade and particle specification should be confirmed before purchase.

Applications

oral care formulations, depending on grade, particle profile, and formulation design
cosmetic raw material use where hydroxyapatite is selected for compatible systems, depending on grade and regulatory requirements
nutritional or specialty calcium-phosphate material programs, subject to grade confirmation and compliance review
biomedical, laboratory, or research-related material use, depending on specification and intended application
specialty powder systems where crystal form, particle size, and surface characteristics are important to formulation performance

Any specific application should be confirmed according to grade, particle size distribution, morphology, purity requirements, and application validation.

For oral-care or nutritional formulations requiring a different calcium-phosphorus material, Calcium Glycerophosphate is supplied as a distinct water-soluble calcium salt.

Packaging and Storage

Standard packaging is available. The product may be packed in bags, drums, cartons, or other suitable containers as applicable to the offered grade and supply format. Customized packaging may be available upon request.

Store in a cool, dry place in tightly closed packaging. Protection from moisture and contamination is recommended during storage and handling. Where a finer particle specification or specialty grade is required, storage and handling conditions should be aligned with the offered grade and application requirements.

FAQ - Technical & Supply Chain

Q:
What is Calcium Microcrystalline Hydroxyapatite CAS 1306-06-5?

A: Calcium Microcrystalline Hydroxyapatite is a microcrystalline calcium phosphate hydroxide, also called hydroxyapatite, hydroxylapatite, or HAP. It is identified by CAS 1306-06-5 and EC 215-145-7, and is normally supplied as a white solid or white powder.
