Science
Mechanism of Action
By organizing into lamellar liquid crystals (LLCs), this ingredient mimics the natural lipid bilayer of human skin. It forms a 'matte velvety veil' that locks in moisture by reducing transepidermal water loss (TEWL) and shields the epidermis from external stressors such as pollution and water exposure.
Research
Clinical Evidence
High confidence2.5%
Key findings
- 01 Clinical HRIPT assessment on 49 subjects confirmed the ingredient is non-sensitizing even at 5% concentrations.
- 02 In vivo testing at 1-3% demonstrated significant water resistance and protective film-forming properties suitable for anti-pollution claims.
- 03 Structural analysis confirms the formation of lamellar liquid crystals at 2-3%, providing superior skin barrier mimicry.

Dusting Analysis
As a functional emulsifier and barrier support agent, concentrations below 1% typically fail to provide the structural lamellar benefits or the intended mattifying film-forming effect.
The Formula
Formulation
Stability
Requires neutralization with an alkaline base to reach its full emulsifying potential. While stable between pH 3.0 and 12.0, the most robust emulsions are formed in the 6.0-7.0 range.
