Science
Mechanism of Action
It functions by lowering surface tension between oil and water phases through its amphiphilic structure, where a C13-15 lipophilic alkyl chain binds to debris and a 21-unit hydrophilic head binds to water, facilitating smooth removal and emulsion stability.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Clinical assessments on related alkyl ethers at 0.5%–3.0% concentrations demonstrated exceptionally low sensitization, with under 1.77% of subjects showing mild reactions.
- 02 Occlusive patch testing at a 10% concentration for related ethoxylated alcohols confirmed only slight irritation, highlighting the inherent mildness of this chemical class.

Dusting Analysis
Because it is primarily used as a functional emulsifier rather than an active, it is rarely 'dusted' for marketing purposes. Concentrations below 0.5% may indicate it is used purely for additive stabilization rather than active cleansing or emulsification.
The Formula
Formulation
Stability
Highly robust across a wide pH spectrum; it maintains structural integrity in the presence of electrolytes, hard water, and both acidic or alkaline environments.
Synergies
- Anionic surfactants
- Cationic conditioning agents
- Nonionic stabilizers
Conflicts
- High concentrations may diminish the antimicrobial efficacy of phenolic preservatives like parabens.
Safety
Safety Profile
Safe for use when formulated to be non-irritating; our standards require high-purity grades to ensure the absence of ethoxylation byproducts like 1,4-dioxane.
