Key value for chemical safety assessment

Genetic toxicity in vitro

Description of key information

Based on negative Ames tests on two fluorine-containing monomers structurally close to HFIB, it can be considered that HFIB is not susceptible to show mutagenic activity in bacterial systems.

Conclusions:
Based on negative Ames tests on two fluorine-containing monomers structurally close to HFIB (C4H2F6): Hexafluoropropylene (HFP, C3F6 - CAS 116-15-4) and Hexafluoroacetone (HFA, C3F6O - CAS 684-16-2), it can be considered that HFIB is not susceptible to show mutagenic activity in bacterial systems.

Endpoint conclusion:
no study available

Additional information

Justification for classification or non-classification

Based on the limited information available showing absence of mutagenic effects in vitro, no classification for genetic toxicity is warranted.
