Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A crosslinked polymer made by reacting hexamethylene diisocyanate (HDI) with polyvinyl alcohol and ethylenediamine — gives tough, flexible films for masks and long-wear makeup. Cured polymer is inert; the watch-out is residual HDI from manufacture.
Function
Skin benefits
- Tough flexible films for long-wear cosmetics
- PVA backbone is water-friendly
- Ethylenediamine crosslinks add resilience
Known concerns
- Manufacturing involves 1,6-HDI, a known respiratory sensitiser
- Cured polymer is inert but residual HDI must be controlled
- Polymer too large to cross intact skin
