Description of key information

Vapour pressure [dodecamethylcyclohexasiloxane]: 4.7 Pa at 25°C

Key value for chemical safety assessment

Vapour pressure:
4.7 Pa
at the temperature of:
25 °C

Additional information

A vapour pressure of 4.7 Pa at 25°C was predicted for the substance using an appropriate QSAR estimation method. In addition, a vapour pressure value of 4.6 Pa at 25°C was calculated for the substance by extrapolation from a temperature-vapour pressure correlation. Both results are considered to be reliable and are assigned as weight of evidence.

In available secondary sources to which reliability could not be assigned, vapour pressure values ranging from 1.2 Pa to 4 Pa at 20 -25°C were reported for the substance.
