Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
(from handbook)
Kinematic viscosity ca 0.202 mm2/s, corresponding to dynamic viscosity ca 0.13 mPa.s, at 20°C.
Very fluid liquid.
Viscosity at 40°C cannot be determined, as the substance is a gas at this temperature.
Key value for chemical safety assessment
- Viscosity:
- 0.202 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
Two literature sources, considered as reliable, provide consistent values, between 0.20 and 0.30 mm2/s at 20-25°C. The result at 20°C, corresponding to the standard, is retained as key data.
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.
