Conclusions:
The determined kinematic viscosity of the substance at 20°C temperature is 16.3 mm2/s and at 40°C temperature 7.63 mm2/s.
Executive summary:

Viscosity of the substance was determined according to the OECD Guideline 114 (GLP study). Ubbelohde capillary viscometer was used to measure the kinematic viscosity at 20 and 40 ºC. The determined average kinematic viscosity of the substance at 20°C temperature is 16.3 mm2/s and at 40°C temperature 7.63 mm2/s.

Description of key information

Key study: OECD 114. GLP study. The determined kinematic viscosity of the substance at 20°C temperature is 16.3 mm2/s and at 40°C temperature 7.63 mm2/s.
