Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Executive summary:

The kinematic viscosity was found to be 1.95 mm2.s-1at 20°C and 1.43 mm2.s-1at 40°C.

The dynamic viscosity was found to be 2.07 mPa.s at 20°C and 1.51 mPa.s at 40°C.

Description of key information

The kinematic viscosity was found to be 1.95 mm2.s-1 at 20°C and 1.43 mm2.s-1 at 40°C.

Key value for chemical safety assessment

Viscosity:
1.95 mm²/s (static)
at the temperature of:
20 °C

Additional information

Viscosity was measured as part of a package of physicochemical testing (Huntingdon Life Sciences, 2013, Study LBM0053). The viscosity was determined according to OECD Method 114 and CIPAC MT 22 and the study was conducted in compliance with GLP.

The kinematic viscosity was found to be     1.95 mm2.s-1at 20°C            and 1.43 mm2.s-1at 40°C.

The dynamic viscosity was found to be       2.07 mPa.s at 20°C              and 1.51 mPa.s at 40°C.

The static (kinematic) viscosity will be reported as the key value for risk assessment (classification for aspiration hazard) is based on this parameter.
