Science
Mechanism of Action
This ingredient utilizes a long-chain carbon backbone (C20-40) paired with extensive ethoxylation to reduce interfacial tension between incompatible phases. On the stratum corneum, it organizes into a hydrophilic occlusive film that traps water molecules, preventing transepidermal water loss (TEWL) without the heaviness typically associated with traditional waxes.
Research
Clinical Evidence
High confidence1.25%
Key findings
- 01 Demonstrated 0.05%–0.1% efficiency in stabilizing nano-emulsions (droplets <350nm) and volatile oils.
- 02 Proven to function as a potent moisture-donating agent and barrier support at concentrations between 0.5% and 2.0%.

Dusting Analysis
While it functions as a stabilizer at very low levels (0.05%), its primary skin-conditioning and barrier-protective benefits require a concentration of at least 0.5%. Formulae using it below this threshold are likely using it for emulsion stability rather than active skin benefit.
The Formula
Formulation
Stability
Highly resilient to high-shear processing and maintains structural integrity across wide temperature variations. It is exceptionally effective at housing sensitive lipophilic actives like retinol.
Synergies
