Science
Mechanism of Action
Functions as a 'mineral sponge' with a porous crystalline structure that selectively adsorbs moisture and volatile malodorous molecules like ammonia and lactate. Beyond simple absorption, it releases essential calcium and magnesium ions to trigger keratinocyte differentiation, while providing bacteriostatic benefits that balance the skin microbiome without disrupting the acid mantle.

Key findings
- 01 Clinical gravimetric studies at 7% concentration demonstrated a 35.5% reduction in sweat after 24 hours, meeting FDA efficacy benchmarks for antiperspirant activity.
- 02 Research indicates that topical application modulates pro-inflammatory cytokines and accelerates collagen I/III production for enhanced wound healing.
- 03 Comparative trials show that concentrations between 10-20% provide superior whitening and surface-polishing effects compared to lower doses.
Transparency
Dusting Analysis
To achieve functional sweat control or significant barrier repair, this mineral requires high inclusion rates (typically 7% or higher). Products listing it near the bottom of the INCI list for 'mineral benefits' are likely using it at sub-therapeutic levels.
The Formula
Formulation
Stability
Highly stable in neutral and alkaline conditions; however, the crystalline structure begins to dissolve if the formulation pH drops below 5.5.
Synergies
- Ceramides
- Glycerin
- Non-acidic soothing botanicals
Conflicts
- Strong Alpha Hydroxy Acids (AHAs)
- Chelating agents
- Formulations with pH < 5.0
Safety
Safety Profile
Recognized by the SCCS as safe up to 29.5% in oral care; it is considered a non-irritating, aluminum-free alternative for sensitive skin types.
