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).
