Science
Mechanism of Action
This short-chain (C8) alkyl ether carboxylic acid reduces the surface tension of water to facilitate the removal of impurities. Its high degree of ethoxylation (9 units) grants it exceptional wetting and dispersing properties, allowing it to solubilize complex oils and prevent debris from re-depositing onto the skin surface.
Research
Clinical Evidence
High confidence2.5%
Key findings
- 01 Clinical evaluations in mixed surfactant systems demonstrate high soil dispersion and lime soap solubilization without disrupting the skin's lipid barrier at 1.0-5.0%.
- 02 Dermatological assessments indicate mild antibacterial and antifungal activity, specifically targeting yeast species like Candida, at concentrations between 0.1-1.0%.
Transparency
Dusting Analysis
In high-end cleansers and micellar waters, this ingredient is typically used at functional levels (1-5%) for its surfactant properties. Concentrations below 0.1% are generally insufficient for effective cleansing or antimicrobial benefits.
The Formula
Formulation
Stability
Demonstrates exceptional stability across extreme pH ranges and is resistant to hydrolysis. It maintains performance in the presence of electrolytes and hard water (lime soap dispersion) and is peroxide-stable.
Synergies
- Mixed surfactant systems
- Low-solubility active ingredients (as a co-surfactant)
Conflicts
- Cationic surfactants
- Concentrated strong oxidizing agents
Safety
Safety Profile
While the pure raw material is a skin and eye irritant, it is non-sensitizing and safe in consumer products at concentrations up to 10%.
