Science
Mechanism of Action
This ingredient functions by intercalating within the lipid bilayers of the stratum corneum, effectively smoothing the skin surface and reinforcing the barrier through semi-occlusive protection. Its low surface tension allows it to act as a precision spreading agent, ensuring uniform delivery of active ingredients and efficient dissolution of lipophilic molecules like UV filters.
Research
Clinical Evidence
High confidence15%
Key findings
- 01 Clinical evaluations at 10-20% concentrations demonstrate a statistically significant reduction in Trans-Epidermal Water Loss (TEWL) compared to standard petroleum derivatives.
- 02 Human Repeat Insult Patch Tests (HRIPT) conducted at 5-15% confirm the ingredient is non-sensitizing and biologically inert on human skin.
Transparency
Dusting Analysis
While often used as a functional solvent at low levels, concentrations below 2% may not provide the characteristic 'dry-touch' emolliency or significant barrier reinforcement seen in clinical data.
