Science
Mechanism of Action
Operates by reducing interfacial tension between oil and water phases through its amphiphilic structure—a hydrophobic C11-15 carbon chain paired with 12 hydrophilic ethylene oxide units. This molecular architecture allows it to stabilize oil-in-water emulsions while solubilizing lipophilic compounds like fragrances into aqueous bases. During cleansing, it forms micelles that encapsulate and lift sebum and impurities from the skin surface.

Dusting Analysis
Not typically subject to dusting practices due to its functional necessity as an emulsifier and surfactant rather than active ingredient status
The Formula
Formulation
Stability
Demonstrates exceptional stability across wide pH range and high-electrolyte environments. Non-ionic nature prevents reactions with most ionic ingredients, enhancing formula compatibility.
Synergies
- Other non-ionic emulsifiers for enhanced stability
- Compatible with most ionic and non-ionic ingredients
Conflicts
- Strong oxidizing agents
- High concentrations may reduce phenolic preservative efficacy through micellar encapsulation
Safety
Safety Profile
CIR Expert Panel approval with 0.3% limit for leave-on applications. Rinse-off products may safely contain up to 10-15% concentrations.
