Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Vapour pressure (dodecamethylpentasiloxane): 7.8 Pa at 25°C (QSAR)
Key value for chemical safety assessment
- Vapour pressure:
- 7.8 Pa
- at the temperature of:
- 25 °C
Additional information
A predicted vapour pressure of 7.8 Pa at 25°C was determined for the substance using a validated QSAR estimation method. The result is considered to be reliable and selected as key study. This value is supported by a vapour pressure of 6±0.5 Pa at 25°C which was based on estimation correlating retention time with temperature. In a secondary source to which no reliability could be assigned, vapour pressure value of 7.99 Pa at 25°C was reported for the substance. The supporting study is in good agreement with the key study.
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.
