DESCRIPTION

Mica Hydroxyapatite Zinc Oxide is a multifunctional composite powder combining mica, hydroxyapatite, and zinc oxide.
Mica Hydroxyapatite Zinc Oxide appears as a fine, white to off-white powder with a silky texture.

Mica Hydroxyapatite Zinc Oxide is insoluble in water but dispersible in cosmetic oils and emulsions.
Mica Hydroxyapatite Zinc Oxide combines the reflective properties of mica with the bioactivity of hydroxyapatite and the UV protection of zinc oxide.

Mica Hydroxyapatite Zinc Oxide exhibits excellent photostability under prolonged sun exposure.
Mica Hydroxyapatite Zinc Oxide is biocompatible and non-toxic, making it suitable for skin-contact products.
Mica Hydroxyapatite Zinc Oxide shows strong adhesion to skin and hair surfaces, enhancing long-lasting protection.

Mica Hydroxyapatite Zinc Oxide is produced through advanced surface modification and composite synthesis techniques.
Mica Hydroxyapatite Zinc Oxide is widely used in cosmetics, pharmaceuticals, dental care, and biomedical applications.

Mica Hydroxyapatite Zinc Oxide is a plate-like, fine mineral composite where ZnO and/or hydroxyapatite are deposited or co-processed on mica substrates.
This engineered morphology provides optical soft-focus, controlled scattering, and improved dispersion in oils and water-based systems.
The presence of hydroxyapatite imparts biocompatibility and enamel affinity, while ZnO contributes broad-spectrum UV attenuation.

Mica Hydroxyapatite Zinc Oxide exhibits good pressability, slip, and adherence on skin and substrates, enabling long-lasting cosmetic performance.

FIRST AID

Inhalation:
If dust is inhaled, move the affected person to fresh air.
Seek medical attention if coughing or breathing discomfort persists.
Provide rest and monitor for irritation.

Skin Contact:
Wash skin with soap and water to remove residual powder.
If irritation develops, seek medical advice.
Remove contaminated clothing and launder before reuse.

Eye Contact:
Rinse cautiously with water for at least 15 minutes, lifting upper and lower eyelids.
Remove contact lenses if present and easy to do; continue rinsing.
Seek medical attention if redness or irritation persists.

Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs or large amounts are swallowed.

Note to Physicians:
Treat symptomatically.
No specific antidote is required; manage irritation conservatively.

HANDLING AND STORAGE

Handling:

Personal Protection:
Wear appropriate PPE such as gloves, safety goggles, and dust mask or respirator when handling powders.
Avoid generating or inhaling dust during processing.

Ventilation:
Ensure adequate local exhaust or general ventilation to control airborne particulates.
Use enclosed transfer where feasible.

Avoidance:
Avoid direct contact with eyes and prolonged skin contact.
Do not eat, drink, or smoke while handling.
Wash hands thoroughly after handling.

Spill and Leak Procedures:
Avoid dust formation; gently sweep or vacuum using HEPA filtration.
Collect material in suitable, labeled containers for reuse or disposal.
Dispose of waste according to local regulations.

Storage:
Store in a cool, dry, well-ventilated area away from moisture and reactive chemicals.
Keep containers tightly closed and properly labeled.
Protect from direct sunlight and high humidity to maintain free-flowing properties.

Handling Cautions:
Use anti-static and dust-control measures during filling and blending.
Ensure containers are sealed properly to prevent contamination and caking.
