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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 7 July - 9 August 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- GLP compliance:
- yes
- Type of method:
- dynamic method
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- <= 37 Pa
- Conclusions:
- The test item has an estimated vapour pressure of <= 37 Pa at 20 °C
- Executive summary:
The vapour pressure of the test item was determined by DSC according to EU Method A.4. The vapour pressue was estimated as <= 37 Pa at 20 °C based on the lowest possible boiling temperature ( Grain-Watson estimation).
Reference
Based on the DSC data, an experimental vapour pressure curve was established. The experimentally-determined vapour pressure of the test item was << 1 mbar at 20 °C which is not in the recommended range of 1 to 1000 mbar for DSC measurements. Estimation using the Grain-Watson method was performed using the lowest possible boiling temperature.
Description of key information
The vapour pressure of the test item was determined by DSC according to EU Method A.4. The vapour pressue was estimated as <= 37 Pa at 20 °C based on the lowest possible boiling temperature ( Grain-Watson estimation).
Key value for chemical safety assessment
- Vapour pressure:
- 37 Pa
- at the temperature of:
- 20 °C
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.
