Description of key information

HFP kinetic dimer is not readily biodegradable (≤12 % BOD/ThOD) in a 28-day Closed Bottle (OECD301D) test.

Key value for chemical safety assessment

Additional information

HFP kinetic dimer is not readily biodegradable and is unlikely to be substantially biodegraded in water systems based on the result of the OECD301D test. However, with a water solubility of 649 µg/L at 22 °C, a vapor pressure of 34.7 kPa at 20 °C, and a dimensionless Henry's Law constant of 5690 at 22 °C, it is unlikely that HFP kinetic dimer would remain in the aquatic compartment over the long term.
