Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Viscosity:
150 mPa · s (dynamic)
at the temperature of:
40 °C

Additional information

No classification for aspiration hazard is required, since the kinematic viscosity at 40°C >20.5 mm²/s (conversion: (Dynamic viscosity mPa s) / (Density g/cm³) = Kinematic viscosity mm²/s).
