Science
Mechanism of Action
This ingredient functions through internal occlusion; its unique molecular structure—combining a branched isostearate chain with a long-chain 1,2-eicosanediol backbone—allows it to seamlessly integrate into the stratum corneum's lipid bilayers. By mimicking the skin's natural architecture, it stabilizes the barrier, effectively reducing transepidermal water loss (TEWL) and restoring elasticity from within.

Key findings
- 01 Clinical data indicates that concentrations between 1-5% provide an immediate 21% increase in skin smoothness. Longitudinal studies over 60 days demonstrate a 100% improvement in skin nourishment metrics when integrated into rich cream formulations.
Transparency
Dusting Analysis
To achieve the lipid-mimetic restructuring effects noted in clinical benchmarks, a concentration of at least 1% is required. Inclusion below 0.5% is typically for label claims and will not provide significant barrier repair.
The Formula
Formulation
Stability
Highly resistant to oxidation due to its fully saturated carbon chains. It remains stable during standard cosmetic heat processing but may undergo hydrolysis in extreme pH environments (<3 or >9).
Synergies
- Ceramides
- Cholesterol
- Squalane
- Phytosterols
Conflicts
- Strong oxidizing agents
- Highly alkaline systems
