Fine

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

A polyurethane built from butanediol and isophorone diisocyanate (IPDI) — used as a long-wear film-former. Fully cured polymer is inert, but unreacted IPDI is a respiratory sensitizer, so QC really matters.
