Reference
Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2013
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: GLP guideline study; results were variable; a maximum value was estimated.
Qualifier:
according to guideline
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
effusion method: vapour pressure balance
Key result
Temp.:
25 °C
Vapour pressure:
< 0.001 Pa
Remarks on result:
other: estimated

No statistical analyses of the data were performed because the balance readings were too low and variable for a line of best fit to have any meaning. Higher temperatures could not be used due to the melting temperature of the test item. Instead it was considered more appropriate to impose a regression slope on a chosen data point to provide an estimate of the maximum value for the vapor pressure at 25 ºC.

Conclusions:
The vapour pressure of the test material was assessed according to OECD Guideline 104 and estimated to be less than 1.2 x 10-3 Pa at 25 ºC.

Description of key information

Vapour pressure is estimated to be less than 1.2 x 10-3 Pa at 25 ºC.

Key value for chemical safety assessment

Vapour pressure:
0.001 Pa
at the temperature of:
25 °C

Additional information
