Safety score · 0–100

Fine

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

A C12-15 fatty alcohol with just 3 EO units — basically a low-HLB co-emulsifier with emollient character. CIR-cleared family; yellow because very low EO behaves more like a lipid than a true surfactant.

Function

SURFACTANT - EMULSIFYING
