Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
The vapour pressure was measured in the range of 26 to 150 °C. No signal was observed in the entire range, meaning that the vapour pressure was below the detection limit of 10 (exp-5) hPa. Subsequently the vapour pressure at 20, 25 and 50 °C was calculated.
Executive summary:

The vapour pressure was measured in the range of 26 to 150 °C. No signal was observed in the entire range, meaning that the vapour pressure was below the detection limit of 10 (exp-5) hPa. Subsequently the vapour pressure at 20, 25 and 50 °C was calculated.
