Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 (decamethyltetrasiloxane): 73 Pa at 25°C (OECD 104)
Key value for chemical safety assessment
- Vapour pressure:
- 73 Pa
- at the temperature of:
- 25 °C
Additional information
A measured vapour pressure of 52 Pa and 73 Pa at 20°C and 25°C were determined for the substance using an appropriate test method. The result is considered reliable and selected as key study. This value is supported by a predicted vapour pressure of 42 Pa at 25°C which was determined for the substance using a validated QSAR estimation method. In other secondary source to which no reliability could be assigned, a vapour pressure of 57 Pa at 25°C was reported for the substance. The supporting studies are 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.
