Reference
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.
