Additional information

A measured kinematic viscosity value of 3.43 mm²/s at 20°C was obtained for the substance using a relevant test method and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study.

The key study is supported by a predicted kinematic viscosity of 3 mm²/s (static) at 20°C using a validated QSAR estimation method.

In available secondary sources to which reliability could not be assigned, viscosity values of 3.65 mPa · s (dynamic) at 20°C and 3 cSt (static) at 25°C were reported.
