Safety score · 0–100
Good
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A high-molecular-weight crosslinked polyurea network — picture a stretchy plastic mesh that wears like a flexible second skin in long-wear foundations and sunscreens. Inert in finished product; residual isocyanate monomers are managed by spec.
Function
Skin benefits
- Forms tough flexible films for long-wear products
- Smooth comfortable skin-feel
- Crosslinked structure means no migration of small molecules
Known concerns
- Manufacturing residuals from isocyanate precursors are tightly controlled
- Polymer itself is too large to penetrate skin
