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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7950 (Vapor Pressure)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- effusion method: isothermal thermogravimetry
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- < 0 Pa
- Test no.:
- #1
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- The vapour pressure of the substance was determined to be very low (< 0.000000013 Pa at 20°C).
Reference
The calculated vapour pressure of the test item was outside the validated range of the method. According to this, the vapour pressure of the test item was determined to be lower than that of benzo(ghi)perylene.
Description of key information
A reliable guideline study conducted via an isothermal TGA effusion method provided very low vapour pressure values (less than the lowest of the reference substances used). The actual value is expected to be lower than the key value used for chemical safety assessment (the lowest reference value available).
Key value for chemical safety assessment
- Vapour pressure:
- 0 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.
