Good

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

A high-EO (40) C12-14 secondary-alcohol ethoxylate used as a mild non-ionic solubiliser and emulsifier. Higher EO count makes it gentler on skin than low-EO siblings, with the routine ethoxylate purity caveat.
