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

A C12-15 fatty alcohol with 4 EO units — low-HLB co-emulsifier favored in oil-rich creams. CIR-cleared family; yellow rather than green because lower-EO grades have a mildly defatting balance on skin.
