Science
Mechanism of Action
Functions as a dual-action anionic/non-ionic surfactant that reduces interfacial tension between water and oils to facilitate emulsion formation. Its 18-19 mole polyoxyethylene chain structure enables formation of a continuous, flexible barrier film on skin surfaces while adjusting ionic character responsively to pH changes for optimal cleansing efficacy.

Clinical Evidence
Medium confidence2.5%
Key findings
- 01 Patent studies demonstrate water-resistant barrier formation and enhanced conditioning when combined with polyamines at 0.1-10% concentrations
- 02 Research at 0.5-5% shows effective stabilization of antimicrobial formulations with excellent skin tolerance
