Science
Mechanism of Action
It forms an invisible mineral film that adsorbs sweat and odors without physically blocking sweat glands. Zinc ions contribute antibacterial and astringent effects. In sunscreens, it functions as a physical UV filter, scattering light to boost SPF.

Key findings
- 01 At 20%, in-vivo tests showed a significant reduction in sweat rate for 24-48 hours, non-irritating and supported skin homeostasis.
- 02 General hydroxyapatite studies indicate 4-7% is optimal for UV screening and SPF boosting, and 10% nano-HA is optimal for enamel remineralization.

The Formula
Formulation
Stability
Stable as an inorganic mineral salt; however, solubility increases and constituent ions are released in acidic environments below pH 4.5. It's designed to release active ions at the skin's natural pH (4.7–5.5).
Conflicts
- Strong acids (causes dissolution/degradation)
- Chelating agents (may sequester the metal ions)
Safety
Safety Profile
While this specific composite lacks CIR review as a single entity, its components are extensively reviewed. It is considered a safe, non-irritating alternative to aluminum chlorohydrate in deodorants.
