About

A perfluoroalkane (PFAS precursor) with significant environmental persistence and bioaccumulation concerns, raising EU regulatory red flags.

Perfluoroisohexane is a fully fluorinated C6 hydrocarbon. As a PFAS-class compound, it is subject to increasing regulatory scrutiny under EU REACH and the proposed PFAS restriction. PFAS compounds are persistent, bioaccumulative, and toxic (PBT). The EU is moving toward broad restrictions on PFAS in consumer products including cosmetics.

Known concerns

  • PFAS-class substance with PBT properties
  • EU regulatory restriction under consideration
  • Environmental persistence and bioaccumulation
  • Aquatic toxicity concern
