C11-15 PARETH-3.

Valuable CAS 173244-48-9 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A gentle non-ionic surfactant and emulsifying agent derived from fatty alcohols and ethylene oxide. With its low HLB value of approximately 8.0, it excels at stabilizing formulations while maintaining skin barrier integrity. This versatile ingredient enhances texture and spreadability across diverse product categories without compromising tolerability.

Summary

emulsifying surfactant cleansing texture enhancer

Science

Mechanism of Action

Functions by reducing interfacial tension between water and oil phases through its amphiphilic molecular structure. The low degree of ethoxylation (3 moles ethylene oxide) creates optimal hydrophile-lipophile balance for stable emulsion formation and improved product texture without disrupting natural skin barrier function.
