Science
Mechanism of Action
By mimicking the skin's natural lipid structure, it diffuses into the epidermis to reinforce the lipid barrier and facilitate efficient water retention. Its unique molecular density (~1.01 g/cm³) allows it to remain suspended in emulsions, preventing phase separation while acting as a delivery vehicle that enhances the diffusion of moisture throughout the stratum corneum.

Clinical Evidence

Key findings
- 01 A 2% concentration was clinically validated as an anti-inflammatory and hydrating agent that preserves skin matrix integrity.
- 02 12-week clinical trials demonstrated significant objective improvements in skin texture, hydration levels, and the appearance of fine lines.

Dusting Analysis
While frequently used at high levels as a base emollient, clinical evidence suggests its active skin-repairing benefits require a minimum concentration of 2%. Formulations using it below 0.5% are likely utilizing it for tactile enhancement rather than therapeutic hydration.
The Formula
Formulation
Stability
Highly resistant to oxidation and maintains a liquid state even at 0°C. Its density, which is nearly identical to water, makes it the gold standard for stabilizing two-phase 'shaking' products and creating uniform oil-droplet dispersions.
Synergies
- Sunscreens (improves pigment dispersion)
- Ceramides (reinforces lipid barrier repair)
Conflicts
- Strongly alkaline environments (causes hydrolysis)
- Strong oxidizing agents
Safety
Safety Profile
Extensively reviewed by the CIR Expert Panel; demonstrated a primary irritation index of only 0.5 in Draize tests. Human patch testing confirms it is non-sensitizing and safe even for eczematous skin.
