Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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)
- GLP compliance:
- no
- Type of method:
- effusion method: isothermal thermogravimetry
- Remarks on result:
- other: The vapour pressure of test item, STEARAMIDE DETA, could not be determined by isothermal thermogravimetric effusion method.
- Transition / decomposition:
- yes
- Transition temp.:
- > 68 - < 121 °C
- Conclusions:
- The vapour pressure of the substance was tested following OECD 104, by isotermal termogravimetric effusion method. Under the experimental conditions no vapour pressure could be determined since the substance melts/decomposes in a range of temperatures between 64.8 and 121°C. Moreover, the determination could not be performed in a temperature range under melting range, because the test item contains water which evaporates up to 100 °C. Therefore no vapour pressure could be measured.
- Executive summary:
The vapour pressure of the substance was tested following OECD 104, by isotermal termogravimetric effusion method. Under the experimental conditions no vapour pressure could be determined since the substance melts/decomposes in a range of temperatures between 64.8 and 121°C. Moreover, the determination could not be performed in a temperature range under melting range, because the test item contains water which evaporates up to 100 °C. Therefore no vapour pressure could be measured.
