C12-13 PARETH-3.

Valuable CAS 66455-14-9 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A non-ionic surfactant and lipophilic emulsifier that stabilizes oil-water interfaces in skincare formulations. With its low HLB value of approximately 8.0, it functions as an effective dispersing agent and spreading enhancer that improves product texture without significant skin barrier disruption.

Summary

emulsifying surfactant cleansing dispersing

Science

Mechanism of Action

Reduces interfacial tension between oil and water phases through its amphiphilic structure, enabling stable emulsion formation while acting as a wetting agent for pigments and enhancing the spreadability of topical formulations

Research

Clinical Evidence

Medium confidence
Effective range 0.125–0.45%
Optimal

0.125%

Key findings

  1. 01 Maximum safe concentration established for topical medicines to minimize irritation potential
  2. 02 Effective as co-emulsifier in foaming cleansers without compromising skin barrier function

Transparency

Dusting Analysis

Not commonly dusted

Used as a functional emulsifier and surfactant rather than an active ingredient, making dusting unlikely in skincare formulations
