Safety score · 0–100

Fine

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

A C9-11 short-chain alcohol ethoxylate with 6 EO units. Combines wetting and emulsifying action; the short alkyl chain makes it more skin-active so it sits a bit higher on the irritation curve than C12-15 cousins.

  • Effective wetting and emulsifying agent
