Safety score · 0–100

Fine

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

A complex polymer network of polyethyleneimine crosslinked with HDI and SMDI diisocyanates. Cured polymer is inert; concerns center on residual diisocyanates (respiratory sensitizers) and trace ethylenimine.
