Science
Mechanism of Action
This ingredient functions as an occlusive emollient by forming a breathable, hydrophobic film over the stratum corneum. Its specific triester structure allows it to integrate into the lipid matrix, effectively sealing in hydration and smoothing the skin's micro-relief.

Key findings
- 01 A 6% concentration was verified as non-sensitizing and non-irritating in Human Repeated Insult Patch Testing (HRIPT).
- 02 Formulations utilizing 0.5-30% demonstrate significant improvements in emulsion spreadability and viscosity stabilization.
- 03 Clinical data indicates a measurable reduction in transepidermal water loss (TEWL) for up to 3 hours following application due to the formation of a protective lipid film.
Transparency
Dusting Analysis
While often used for texture, at least 0.5% is required to provide functional barrier support. Concentrations below this are likely used only for label claims rather than physiological efficacy.
The Formula
Formulation
Stability
Highly resistant to oxidation when saturated; features a unique melting range of 30-44°C which creates a 'melt-on-skin' effect.
Synergies
- Ceramides
- Squalane
- Fatty Acids
Conflicts
- Strong oxidizing agents
- Extreme pH levels below 4.0 or above 8.0
Safety
Safety Profile
Considered safe by the CIR Expert Panel even at high concentrations, making it an excellent alternative to synthetic occlusives.
