Safety score · 0–100

Fine

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

A long-chain olefin/maleic-ester copolymer used as a film-former in colour cosmetics and sunscreens. Skin-safe at use levels (too large to penetrate), but the persistence/microplastic environmental concern is the main caveat.

Function

FILM FORMING

Skin benefits

  • Film-former — transfer-resistant cosmetics
  • Water-resistance for sunscreens and make-up
  • Low dermal penetration (high MW)

Known concerns

  • Synthetic polymer — microplastic / persistence concern in wash-off
  • Possible residual maleic anhydride monomer at low ppm
