Science
Mechanism of Action
This long-chain fatty alcohol functions by organizing into lamellar (liquid crystal) structures that replicate the skin's natural lipid bilayer. This organization strengthens the epidermal barrier and facilitates a sustained release of hydration while providing significant water resistance and structural integrity to the formulation.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 A 30-day clinical evaluation of a 3% C20-22 blend demonstrated a significant reduction in skin roughness and visible wrinkle depth.
- 02 In vivo testing at 2% concentration showed a 48.6% increase in skin moisturization after one hour, with 34.2% retention maintained at the 24-hour mark.

Dusting Analysis
Because this ingredient is a structural co-emulsifier, it is typically used at functional levels (2-5%) to ensure emulsion stability; use below 1% is generally insufficient to achieve its clinical hydration or texture-modifying benefits.
The Formula
Formulation
Stability
Highly resilient across a wide pH range and salt-tolerant. Requires heating to 75-80°C during the oil phase for proper integration. Improves freeze-thaw stability of emulsions.
Synergies
