Science
Mechanism of Action
Bakuhan utilizes a high-surface-area porous structure (approximately 6 m2/g) to act as a molecular sieve, trapping heavy metals, excess sebum, and environmental toxins within its 0.5-micron pores. Simultaneously, it engages in mineral elution, releasing over 19 essential trace elements including Zinc and Selenium, while providing natural antibacterial activity against pathogens like S. aureus.

Key findings
- 01 Certified as an approved medicinal substance by the Japanese Ministry of Health (1995) for skin applications.
- 02 Demonstrated 0.5-micron filtration effect for the adsorption of Lead, Mercury, and Chromium in clinical cleansing trials.
- 03 Proven inhibition of Candida albicans and Staphylococcus aureus growth in medical school studies.

Dusting Analysis
Because it is a cost-effective mineral, it is rarely 'dusted' for marketing; however, concentrations below 1% may fail to provide the significant ionic exchange and adsorption surface area required for clinical-grade purification.
The Formula
Formulation
Stability
Highly stable mineral powder. While the bulk material is water-insoluble, it elutes water-soluble ions over time, naturally buffering the formulation toward a slightly alkaline state.
Synergies
- Micronized Silica
- Hydrating Humectants
- Zinc
Conflicts
- Low-viscosity aqueous solutions (requires suspension agents)
- Non-micronized particles (can cause mechanical abrasion)
Safety
Safety Profile
While not specifically reviewed by the CIR, its primary components—natural silicates—are considered safe. It is medically certified in Japan for therapeutic use.
