Science
Mechanism of Action
This amphiphilic molecule integrates into the lipid bilayer of the stratum corneum, where it stabilizes the membrane structure and modulates the penetration of potential irritants. By reducing the critical micelle concentration (CMC) of surfactants, it minimizes skin-protein denaturation during cleansing.

Key findings
- 01 In vitro evaluation of lipid membrane stabilization and transepidermal water loss (TEWL) reduction in surfactant-stressed skin models.
Transparency
Dusting Analysis
Frequently included at ultra-low concentrations (below 0.1%) to claim 'soothing' properties in rinse-off products, whereas concentrations of 0.5% or higher are required for measurable barrier protection.
