Science
Mechanism of Action
Utilizes its dual-natured molecular structure—featuring a lipophilic C12-15 carbon chain paired with a hydrophilic PEG-11 head—to reduce interfacial tension between oil and water phases, enabling stable emulsion formation and enhanced product spreadability.

Key findings
- 01 Human Repeat Insult Patch Tests on related alkyl PEG ethers showed zero sensitization events and no clinically significant irritation at 5-15% concentrations
- 02 Rabbit primary irritation studies demonstrated minimal dermal irritation potential even at 50% concentration

Dusting Analysis
As a functional emulsifier rather than a marketed active, this ingredient is rarely featured prominently in marketing claims or used in ineffective concentrations for appearance purposes.
The Formula
Formulation
Stability
Demonstrates exceptional stability across acidic, neutral, and alkaline conditions with superior resistance to strong bases compared to other ethoxylated alcohols. Cloud point occurs at 60-64°C in 10% NaCl solution.
Conflicts
- Strong oxidizing agents
- Strong reducing agents
Safety
Safety Profile
Safety contingent on proper manufacturing processes that minimize 1,4-dioxane and ethylene oxide impurities through vacuum stripping or equivalent purification methods.
