Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

At 40°C: 26.522 and 26.443 cSt

Conclusions:
The kinematic viscosity of the substance was determined to be 71.93 cSt (mean of 2 results) at 20°C and 26.48 cSt (mean of 2 results) at 40°C.

Description of key information

The kinematic viscosity of the substance was determined in a GLP study according to CIPAC test method MT 22 to be 71.93 cSt at 20 °C, applying a capillary U-tube viscometer (Younis S, 2012)
