Science
Mechanism of Action
By lowering the surface tension of aqueous solutions, this ingredient acts as a bridge between immiscible phases. With a Hydrophile-Lipophile Balance (HLB) of approximately 12, it primarily stabilizes oil-in-water (O/W) emulsions and enables the removal of lipophilic impurities from the skin surface.
Research
Clinical Evidence
High confidence10%
Key findings
- 01 A Human Repeat Insult Patch Test (HRIPT) documented by the Cosmetic Ingredient Review (CIR) evaluated concentrations between 5% and 25%, concluding the ingredient is a non-sensitizer despite occasional mild, transient irritation at high thresholds.

Dusting Analysis
As a functional emulsifier rather than a primary bioactive, it is rarely 'dusted' for marketing claims. It is typically included at levels necessary for structural stability.
The Formula
Formulation
Stability
Exhibits exceptional stability in the presence of hard water, electrolytes, and both oxidizing and reducing agents. Concentrations exceeding 20% may result in increased viscosity or formulation haziness.
Synergies
- Anionic surfactants
- Cationic surfactants
- Non-ionic surfactants
Conflicts
- None identified; highly compatible across diverse chemical systems.
Safety
Safety Profile
Safety is contingent on purity standards. Ethoxylated ingredients must be monitored for 1,4-dioxane and ethylene oxide, with finished products ideally containing less than 1 ppm of these impurities.
