Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

21 °C

Additional information

A number of consistent value are reported for the vapour pressure across a variety of secondary sources indicating a vapour pressure of around 9.7 - 10.3kPa at around 20C. Because of the impact on exposure assessment (the cut off between medium and high fugacity bands as used in ECETOC TRA exposure prediction tool) a conservative choice of 10.3kPa is selected as the key parameter for this end point.
