Relative Density (hexamethyldisiloxane): 0.7638 at 20°C

Key value for chemical safety assessment

Relative density at 20C:
0.764

Additional information

A relative density value of 0.7638 at 20°C was reported in a handbook or 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 selected as key study. In another reliable study, a density value of 0.76 g/cm3 at 25°C was reported for the substance.

In other secondary sources to which no reliability could be assigned, density values of 0.7579 g/cm3 at 25°C, 0.765 g/cm3 at 20°C and approximately 0.8 g/cm3 at 20°C were reported for the substance.
