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

An isoprene/maleic-anhydride/PEG-40 copolymer used as a film-former. Large polymer, low skin absorption, but PEG component grade quality drives the overall safety story.

Skin benefits

  • Film former — improves wear and water resistance
  • Texture/viscosity modifier
  • Compatible with both oil and water phases

Known concerns

  • PEG residual ethylene oxide and 1,4-dioxane depend on grade
  • Limited skin penetration but data is grade-dependent
