Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- (Q)SAR
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Qualifier:
- according to guideline
- Guideline:
- other: QSAR method (MPBPVPWIN)
- GLP compliance:
- not specified
- Type of method:
- other: QSAR model
- Test no.:
- #1
- Temp.:
- 25 °C
- Vapour pressure:
- 0 mm Hg
- Remarks on result:
- other: Antoine method (estimated)
- Test no.:
- #2
- Temp.:
- 25 °C
- Vapour pressure:
- 0 mm Hg
- Remarks on result:
- other: Modified Grain method (estimated)
- Test no.:
- #3
- Temp.:
- 25 °C
- Vapour pressure:
- 0 mm Hg
- Remarks on result:
- other: Mackay Method (estimated)
- Conclusions:
- The vapor pressure has been estimated by QSAR tool (MPBPVPWIN) using 3 validated method Antoine Method, Modified grain Method and Mackay Method.
As expected for a sodium organic salt, the vapor pressure of the test item is very low, comprised between 3.85E-9 and 1.91E-8 mm Hg at 25 °C calculated using the QSAR tool.
The modified Grain method is estimated to be the best all-around VP estimation method currently available as described in the MPBPVPWin user guide. The value 1.91E-8 mmHg (2.54E-6 Pa) estimated with the modified Grain method will be retained.

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.
