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.
