Additional information
A measured kinematic viscosity value of 0.585 mm2/s at 20°C was obtained for the substance using a Ubbelohde viscosimeter in accordance with DIN 51562 test method. The result is considered to be reliable and is selected as key study.
In a second study, kinematic viscosity value of 0.55 mm²/s at 25°C was measured for the substance using relevant test methods. Although, full details are not available, the result is considered reliable. Similarly, a predicted kinematic viscosity value0.7 mm2/s at 20°C of was determined for the substance using a validated QSAR estimation method.
In a secondary source to which reliability could not be assigned, a dynamic viscosity value of 0.6 mPa.s at 25°C was reported for the substance.
