About
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
Skin benefits

- Useful in waterless or oil-based cleansers
- Compatible with surfactant blends
Known concerns
- Very low EO count means more skin defatting potential
- Ethoxylated material — purified grade required
- No direct skin-care benefit
