Safety score · 0–100
Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A fatty PEG-400 / isocyanate copolymer used as a film former and thickener. Large polymer, low skin uptake; safety depends on residual purity of PEG and isocyanate monomers.
Skin benefits
- Film former / texture enhancer
- Thickening and viscosity control
- Compatible with anhydrous systems
Known concerns
- PEG residual ethylene oxide / 1,4-dioxane depend on grade
- Isocyanate-based prepolymer chemistry — pure cured polymer is inert, but residuals matter
- Limited public safety review
