Fine

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

A C12-15 fatty alcohol with only 5 EO units — sits on the lipophilic side of the alkyl-ether family. CIR-cleared, but lower-EO grades earn yellow because they are slightly more defatting and less water-soluble.
