Safety score · 0–100

Fine

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

A polyurethane-style film former made from polybutanediol-22 and IPDI. Gives long-wear cosmetic films better water resistance. Cured polymer is generally safe; residual monomer is the concern.

Skin benefits

  • Film-forming polymer for long-wear cosmetics
  • Helps water and rub resistance
  • Skin-surface only at high molecular weight

Known concerns

  • IPDI base raises questions about residual diisocyanate monomer
  • Limited compound-specific safety data
  • Potential sensitisation if unreacted monomer is present
