Function

BINDING

Skin benefits

  • High molecular weight polymer used as film former and rheology modifier
  • Polyurethane class generally inert on intact skin once cured
  • Provides long-wear film performance in color cosmetics and treatments
  • Class reviewed broadly by CIR with several variants deemed safe

Known concerns

  • Built from IPDI (isophorone diisocyanate); residual isocyanates are sensitizers and respiratory irritants
  • HEMA (2-hydroxyethyl methacrylate) end groups are known skin sensitizers when unreacted
  • Quality depends heavily on full polymerization and removal of unreacted monomers
  • No dedicated CIR or SCCS opinion located for this specific copolymer
