Science
Mechanism of Action
It organizes into a structured, biomimetic lipid bilayer on the stratum corneum. This 'intelligent' barrier dynamically adapts to external environmental shifts, specifically increasing its resistance to water loss in low-humidity conditions to maintain hydration and elasticity.

Key findings
- 01 Demonstrated statistically significant improvements in skin smoothness (p=0.0273) and radiance (p=0.0674) in double-blind trials.
- 02 Clinically proven to provide up to 72 hours of continuous hydration through barrier reinforcement.
- 03 Instrumental analysis confirmed a measurable reduction in visual xerosis (dryness) and enhanced sensorial perception of moisturization.

Dusting Analysis
Because it is often part of a larger moisturizing complex (like DuraQuench IQ), brands may include it at sub-functional levels (<1%) for marketing claims. Efficacy for 72-hour hydration is typically validated at 1% or higher.
The Formula
Formulation
Stability
A stable waxy solid requiring a melting phase of 65-75°C. It is resilient within standard cosmetic pH ranges but should not be exposed to extreme alkaline or acidic conditions which may trigger hydrolysis.
Synergies
- Ceramides
- Squalane
- Glycerin
- Cholesterol
Conflicts
- Strong oxidizing agents
- Strong acids
- Strong bases
Safety
Safety Profile
Reviewed by the CIR Expert Panel in 2015 and 2020; it is considered non-irritating and safe for use in concentrations significantly higher than required for efficacy.
