Additional information

A GLP study was conducted (BASF 11L00464) in accordance with the OECD Guideline for the Testing of Chemicals 114, Viscosity of liquids.                                                                   

The kinematic viscosity was measured by a capillary viscosimeter. The dynamic viscosity was calculated by the equation n = v * p (p is density).

The dynamic viscosity of the substance was determined to be

1.47 mPa*s at 20°C and 0.95 mPa*s at 40 °C and

the kinematic viscosity of the substance was determined to be

1.73 mm²/s at 20°C and 1.15 mm²/s at 40°C.
