Science
Mechanism of Action
As a non-ionic amphiphilic molecule, it lowers surface tension to facilitate the mixing of incompatible liquids. It organizes into micelles that trap lipophilic debris, such as excess sebum and pollutants, allowing them to be rinsed away without disrupting the skin's moisture barrier.

Key findings
- 01 Evaluation of related alkyl PEG ethers (C14-15 Pareth-7) indicates that while undiluted forms may cause mild irritation, concentrations standardized for cosmetic use remain non-irritating.
- 02 Safety assessments on ethoxylated fatty alcohols suggest that leave-on concentrations below 5% maintain an excellent safety profile with zero sensitization.

Dusting Analysis
Because it is a functional surfactant rather than an active treatment, 'dusting' is less relevant; however, concentrations below 1% in primary cleansers may indicate it is used only as a secondary solubilizer rather than a primary cleaning agent.
