Science
Mechanism of Action
This ingredient acts as a multi-functional emollient and co-surfactant. By forming a breathable film on the skin's surface, it physically restricts transepidermal water loss (TEWL) while simultaneously delivering high concentrations of linoleic acid and antioxidant selenium to reinforce the lipid barrier at a cellular level.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Clinical evaluations demonstrate significant reduction in TEWL and barrier restoration when used between 1.0% and 5.0% due to high Omega-6 content.
- 02 Safety assessments by the CIR confirm the ingredient is non-sensitizing and non-irritating even at elevated concentrations up to 31.0%.
Transparency
Dusting Analysis
To achieve measurable barrier restoration and TEWL reduction, concentrations should meet or exceed 1.0%. Formulations including this at 'label-only' levels (below 0.5%) are unlikely to provide the advertised emollient benefits.
The Formula
Formulation
Stability
Maintains integrity within standard cosmetic pH ranges; however, extreme environments (below pH 4 or above pH 9) can trigger hydrolysis of the ester bond.
Synergies
- Hyaluronic Acid
- Ceramides
- Glycerin
Conflicts
- Strong oxidizing agents
- Extreme acidic or alkaline environments
Safety
Safety Profile
While 5.0% is the standard industrial recommendation for aesthetic stability, safety data supports much higher usage levels.
