*Different capillaries were used at 20 °C and 40°C, resulting in different flow times

Conclusions:
The kinematic viscosity of the substance is 1.456 mm²/s at 20°C and 1,107 mm²/s at 40°C
Executive summary:

The kinematic viscosity of the substance is 1.456 mm²/s at 20°C and 1.107 mm²/s at 40°C when tested in a capillary viscometer.

Description of key information

 The kinematic viscosity at 40°C is < 7 mm²/s according to the SDS. This is confirmed in a study which showed a kinematic viscosity of 1.456 mm²/s at 20°C and 1,107 mm²/s at 40°C

Key value for chemical safety assessment
