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 predicted vapour pressure of 4.7 Pa is calculated at 25°C by using an appropriate QSAR prediction method, and a vapour pressure value of 4.6 Pa is determined at 25°C by extrapolation from a temperature-vapour pressure correlation. Both results are considered to be reliable and are assigned as weight of evidence.

Vapour pressure values ranging from 1.2 Pa to 4 Pa at 20 -25°C were reported in various sources. The original references were not available for review and no further information is available. The reliabilities of these results are not assignable.
