Caution

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

A fully fluorinated PFAS molecule, a so-called forever chemical. Even though it is inert on skin, it persists permanently in the environment — EU is phasing PFAS out.

Skin benefits

  • Oxygen-carrying property used in some specialty creams
  • Inert at point of application

Known concerns

  • PFAS — EU is restricting per- and polyfluorinated substances under REACH (universal PFAS restriction proposal 2023)
  • Extreme environmental persistence (forever chemical)
  • Bioaccumulation concerns
  • Likely phase-out from cosmetics
