Additional information
A study was conducted to assess the viscosity of the test substance. The study was considered reliable as it was conducted on the registered substance according to OECD Testing Guideline 114. The dynamic viscosity of the test substance was found to be 21000 mPa.s at 20°C and 1800 mPa.s at 40°C. Using the dynamic viscosity and the densities the kinematic viscosity was calculated as 19000 mm2/s at 20°C and 1600 mm2/s at 40°C.
