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 built from HPMA, polybutanediol-9 and TMHDI for flexible long-wear films. Safe when fully cured; residual diisocyanate monomer is the safety driver.

Skin benefits

  • Polyurethane-style film former built on TMHDI for flexibility
  • Long-wear performance in cosmetics
  • Stays surface-only at high MW

Known concerns

  • TMHDI is a diisocyanate; residual monomer in the polymer must be controlled
  • Limited public toxicology on this exact copolymer
  • Possible sensitisation if monomer is free
