Safety score · 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A very-low-EO (1 EO) C12-13 fatty-alcohol ethoxylate. The minimal EO count makes it strongly lipophilic — excellent at solubilising oils but more defatting on skin than higher-EO grades, so use levels matter.

Function

SURFACTANT - CLEANSING

Skin benefits

  • Useful in waterless or oil-based cleansers
  • Compatible with surfactant blends

Known concerns

  • Very low EO count means more skin defatting potential
