Science
Mechanism of Action
It acts as a breathable occlusive agent by creating a hydrophobic film over the stratum corneum. This layer physically prevents trans-epidermal water loss (TEWL) while also serving as a structural stabilizer that improves the spreadability and viscosity of emulsions and anhydrous systems.
Research
Clinical Evidence
High confidence2%
Key findings
- 01 A 2015 CIR safety assessment confirmed that concentrations up to 2% are non-irritating and safe for leave-on face and neck applications.
- 02 Clinical data from US Patent 9,913,792 demonstrated that a 0.3% concentration, when combined with niacinamide, effectively supports skin health and appearance.

Dusting Analysis
While often used at lower levels for texture, concentrations below 0.2% may not provide significant barrier-repair benefits. It is rarely used as a marketing 'claim' ingredient, reducing the likelihood of intentional dusting.
