Science
Mechanism of Action
By forming a hydrophobic, occlusive film, it limits trans-epidermal water loss (TEWL) and reinforces the stratum corneum's lipid phase behavior. This physical barrier smooths the skin's micro-relief while maintaining essential moisture levels within the epidermis.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Plastic occlusion stress tests indicate that related alkyl esters significantly enhance the water permeability barrier function of the stratum corneum.
- 02 Human clinical trials using concentrations between 1.5% and 5% demonstrated zero evidence of sensitization or irritation across diverse skin profiles.
Transparency
Dusting Analysis
As a structural emollient, it is rarely 'dusted' because its primary value lies in its texture-enhancing and occlusive properties, which typically require inclusion rates above 1% to be functional.
The Formula
Formulation
Stability
Highly resistant to oxidation and rancidity; however, exposure to extreme pH levels (below 3.0 or above 10.0) can trigger hydrolysis.
Synergies
- Ceramides
- Isostearyl Isostearate
- Fatty Acids
Conflicts
- Strong oxidizing agents
- Highly alkaline environments
