Results and discussion
Vapour pressure
- Temp.:
- 25 °C
- Vapour pressure:
- < 0.001 Pa
- Remarks on result:
- other: No vapour pressure was observed (up to 150.1°C)
Any other information on results incl. tables
- The vapour pressure was measured at: 33.3, 45.8, 56.9, 65.6, 75.3, 85.6, 93.9, 103.4, 113.4, 120.7, 129.3, 139.0, 146.5 and 150.1 °C
- As no vapour pressure was observed in the entire range, it is concluded that the vapour pressure of the substance is below the detection limit of the used test system, which is 0.001 Pa, in this temperature range
- The vapour pressure of the substance at 25 degrees Celsius will be much lower, as the vapour pressure of the substance is already below 0.001 Pa at 150.1 °C, but it is not considered needed to impose a regression slope on a chosen data point to provide a lower estimate
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the substance is <0.001 Pa (at 25 degrees Celsius), determined with the vapour pressure balance method in accordance with EU Method A.4 (1992) and GLP.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
