Description of key information

For the vapour pressure endpoint we have two pieces of data which provides information on the vapour pressure of the material UC. A vapour pressure study as undertaken on the surrogate material EHMC and the vapour pressure was extremely low (2.8E-8 Pa). We have a QSAR on the test material UC which shows the vapour pressure to be a very similar value (1.96E-8 Pa).

Additional information

For the vapour pressure endpoint we have two pieces of data which provides information on the vapour pressure of the material UC. A vapour pressure study as undertaken on the surrogate material EHMC and the vapour pressure was extremely low (2.8E-8 Pa). We have a QSAR on the test material UC which shows the vapour pressure to be a very similar value (1.96E-8 Pa). In this case we have chosen the QSAR to be the key study as the result was undertaken on our actual substance rather than a surrogate material. Since the result of the QSAR was so low it was decided that an actual study was not necessary.
