Science
Mechanism of Action
Functioning as both an astringent and a structural setting agent, this mineral facilitates an exothermic reaction when combined with water, converting from a hemihydrate to a dihydrate matrix. This process generates a mild, localized increase in skin temperature and creates an occlusive seal, which significantly enhances the skin's permeability and absorption of co-formulated nutrients.

Clinical Evidence
High confidence20%
Key findings
- 01 Clinical evaluation at 20.0% concentration using Finn chambers demonstrated zero irritation potential across test subjects.
- 02 Studies on alginate-based delivery systems confirm its role as a primary setting agent that maintains an occlusive environment for improved ingredient penetration.

Dusting Analysis
In performance skincare, this ingredient is typically used at high concentrations (10-40%) to achieve its structural and occlusive benefits. Usage below 1% generally indicates a secondary role as an anti-caking agent or opacifier rather than a functional skin-delivery tool.
The Formula
Formulation
Stability
Exhibits retrograde solubility, becoming less soluble as temperature rises. Highly stable in its dry, powdered state but reacts rapidly with water to form a solid mass.
