- <= 0 Pa
- Remarks on result:
- other: extrapolated
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- <= 0 Pa
- Remarks on result:
- other: extrapolated
- Conclusions:
- The vapour pressure of the substance is determined to be 0.00012 Pa at 25 °C (extrapolated) or 0.000061 Pa at 20 °C (extrapolated).
- Executive summary:
The vapour pressure of the substance was determined in a study conducted acccording to EU Method A.4 and OECD Guideline 104. The thermobalance (diffusion controlled evaporation) method was used for this purpose. Based on the findings of the study, the vapour pressure of the substance is determined to be 0.00012 Pa at 25 °C (extrapolated) or 0.000061 Pa at 20 °C (extrapolated).

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.
