Conclusions:
The viscosity of test item was determined according to OECD 114 guideline, using a rotational viscometer.
The viscosity of test item was 22.3 mPa.s at 20°C and 10.9 mPa.s at 40°C for a speed of 10 rpm.
Executive summary:

The viscosity of test item was determined according to OECD 114 guideline, using a rotational viscometer.

The viscosity of test item was 22.3 mPa.s at 20°C and 10.9 mPa.s at 40°C for a speed of 10 rpm.

Description of key information

The viscosity of test item was 22.3 mPa.s at 20°C and 10.9 mPa.s at 40°C for a speed of 10 rpm.
