Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Density (hexamethylcyclotrisiloxane): 1.19 g/cm3 at 25°C
Key value for chemical safety assessment
Additional information
A solid phase density value of 1.19 g/cm³ is reported at 25°C in a handbook which has been subject to peer-review and in which the original data sources are traceable (DIPPR 2006). The result is considered to be reliable. A source to which reliability could not be assigned gave an extrapolated liquid phase density of 0.95 g/cm³ at 25°C. Another source to which reliability could not be assigned gave a density of 0.86 g/cm³ at 20°C. No details are available, therefore, this result may also relate to liquid phase density.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
