Science
Mechanism of Action
It physically binds to excess sebum and lipids on the skin surface for a mattifying effect. In formulations, its thixotropic 'house of cards' structure thickens products and suspends insoluble particles.

Key findings
- 01 Topical application of 2.0g Magnesium Aluminum Silicate daily for 1 week produced no adverse effects or irritation on human skin.
- 02 Aluminum Silicate up to 25% was predicted non-irritating in EpiDerm skin assays and non-sensitizing in LLNA studies.

Dusting Analysis
Inhalation of fine dust or respirable particles is a safety concern in occupational settings or when used in spray formulations, requiring minimized exposure.
The Formula
Formulation
Stability
Highly stable across a wide pH range (4.0-11.0). Exhibits thixotropic behavior, thinning upon shear and thickening at rest, with enhanced stability in acidic conditions (pH 4-5).
Conflicts
- High electrolyte concentrations
- Certain cationic surfactants
Safety
Safety Profile
Not significantly absorbed through skin. The primary safety concern is inhalation of fine dust in occupational settings or spray applications.
