Description of key information

The viscosity was determined according to OECD 114 guideline using a rotational viscometer.
The viscosity of the test item is:
4.93 at 40°C

Key value for chemical safety assessment

Viscosity:
4.93 mPa · s (dynamic)
at the temperature of:
20 °C

Additional information

The substance shows Newtonian behaviour. Small irregularities in the shear rate vs. shear stress plot are due to instrumental errors caused by the low forces at small shear rates. To minimise such errors, evaluation of the viscosity was performed only for shear rates above 100 s-1. Dynamic viscosity: 4.93 ± 0.09 mPa.s at 40 °C

Since the test material was only partially liquid at 20°C the test was only performed at 40°C. The keyparameter presented is the viscosity at 40°C
