Description of key information

Vapour pressure: 45 Pa at 20 °C

Key value for chemical safety assessment

Additional information

A vapour pressure value of 45 Pa at 20 °C was obtained using an appropriate QSAR method (Reconsile 2009). The result is considered to be reliable and has been assigned as the key study. No other results are available.

 

The vapour pressure of the silanol hydrolysis product has been predicted to be 0.00012 at 20 °C, using a validated QSAR prediction method. The result is considered to be reliable.
