Science
Mechanism of Action
Functions by positioning its hydrophilic polyethylene glycol chain toward water while its hydrophobic C11-15 carbon chain orients toward oil, creating stable microemulsions that improve product spreadability and ingredient solubilization.

Clinical Evidence
High confidence3.25%
Key findings
- 01 Human Repeated Insult Patch Test at 30% concentration (6% effective) demonstrated no primary or cumulative skin irritation or sensitization (CIR, 2012)
- 02 Hair care formulations show optimal anti-frizz and conditioning benefits at 1.5-5% concentrations as co-emulsifier
Transparency
Dusting Analysis
Primarily used as functional emulsifier rather than marketing ingredient, dusting unlikely due to technical necessity in formulations
The Formula
Formulation
Stability
Demonstrates broad compatibility with anionic, cationic, and non-ionic surfactants due to non-ionic nature; particularly stable in microemulsion systems
Synergies
- Other non-ionic surfactants
- Anionic surfactants
- Cationic surfactants
- Lipophilic actives requiring solubilization
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
CIR Expert Panel confirms safety when formulated to be non-irritating; manufacturing requires control of potential trace impurities including 1,4-dioxane and ethylene oxide
