Description of key information

Boiling point [dodecamethylcyclohexasiloxane]: 245°C at 1013 hPa

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
245 °C

Additional information

A boiling point value of 245°C was reported for the submission substance in a handbook which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable. In addition, a boiling point value of 220°C at 1013 hPa was obtained for the substance using a validated QSAR estimation method. The result is considered to be reliable. These two sources of data are used as weight of evidence for this endpoint.

In available secondary sources to which reliability could not be assigned, a boiling point of 245°C at 1013 hPa was reported for the substance.
