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).
