Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

In accordance with Column 2 of REACH Annex VIII 9.2.2.1, hydrolysis as a function of pH does not need to be done. PFBE is a highly volatile liquid of low water solubility (15.6 mg/l).  Volatilisation from the aquatic environment is expected to be rapid, based on the estimated Henry's law constant (3 -100 atm.m3/mol) and this compound's high vapour pressure (22 kPa at 20°C). Consequently detectable concentrations will be hard to achieve in the aquatic enviroment.
