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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Validity criteria for the measurement of the vapour pressure:
| Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
| The vapour pressure should be determined for at least two temperatures. Three or more are preferred in the range 0 to 50 °C, in order to check the linearity of the vapour pressure curve. | 17 values in a temperature range of 50 to 170 °C are stated. | Yes (considering the huge amount of measured data, the preferred temperature range may be neglected, here) |
| A log p versus 1 /T curve should be stated. | The curve can be found in the raw material data. | Yes |
| An estimate of the vapour pressure at 20 or 25 °C should be stated. | Both are extrapolated and stated. | Yes |
Description of key information

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
