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

A PEG-modified polyurethane built from saturated methylenebis(cyclohexyl isocyanate) (SMDI). Used as a long-wear film former. Cured polymer is inert; SMDI residue and PEG dioxane control are the key safety levers.
