Science
Mechanism of Action
Functions as a surface-active agent that decreases interfacial tension between oil and water, enabling efficient removal of debris, sebum, and environmental pollutants while facilitating stable emulsion formation in skincare formulations

Clinical Evidence
High confidence2.5%
Key findings
- 01 Patch testing on 3,186-6,202 patients demonstrated exceptionally low sensitization rates of 0.25%-0.34% for related alkyl PEG ethers at 0.5-3.0% concentrations
- 02 High-concentration dermal studies (10-25%) on analogous pareth compounds showed only negligible to slight irritation, confirming excellent skin tolerance
Transparency
Dusting Analysis
As a functional surfactant with established safety data, this ingredient is typically used at effective concentrations rather than being subject to dusting practices
The Formula
Formulation
Stability
Demonstrates exceptional pH stability due to non-ionic structure, with optimal performance at skin-neutral pH 4.5-5.5. Shows superior resistance to hard water compared to ionic surfactants
Conflicts
- Strong oxidizing agents
- High electrolyte concentrations
Safety
Safety Profile
CIR assessment of 131 alkyl PEG ethers supports safety when formulated to minimize irritation. Leave-on products typically use 0.1-5%, while rinse-off formulations may contain up to 10%
