Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018-09-11 to 2018-11-06
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- effusion method: Knudsen cell
- Key result
- Temp.:
- 150 °C
- Vapour pressure:
- 0.002 Pa
- Conclusions:
- The vapour pressure of the test item is 0.00248 Pa at 150 °C.
- Executive summary:
The vapour pressure of the test item was determined according to OECD 104 resp. EU A.4 using the effusion method (weight loss) and was examined at nine different temperatures. No temperatures could be evaluated as they showed no reproducible or relevant weight loss. As a calculation on base of the measured weight losses was not possible, the highest vapour pressure, derived from all measurements, is stated as limit value. Vapour pressure at 150 °C: 0.00248 Pa.
Reference
Vapour pressure was examined at nine different temperatures. No temperatures could be evaluated as they showed no reproducible or relevant weight loss. As a calculation on base of the measured weight losses was not possible, the highest vapour pressure, derived from all measurements, is stated as limit value. Vapour pressure at 150 °C: 0.00248 Pa.
Positive control:
For Diethylphthalate the following vapour pressure was determined: 0.169 Pa at 30 °C. The criterion for the vapour pressure of the positive control is 0.044 - 0.244 at 30 °C. Therefore, the study result can be considered valid.
Description of key information
The vapour pressure of the test item is 0.00248 Pa at 150 °C.
Key value for chemical safety assessment
- Vapour pressure:
