Description of key information

Melting point (hexamethyldisiloxane): -68.2°C at 101.3 kPa

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-68.2 °C

Additional information

A melting point value of -68.2°C was reported for the substance in a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable and is assigned as key study. This value is supported by another melting point of -66°C which was reported for the substance in a handbook or collection of reliable data.

In secondary sources to which no reliability can be assigned, melting point values of -68°C, and -68.2 to -68.7°C were reported for the substance.
