- Conclusions:

- Executive summary:
The dynamic viscosity od MDIPA Esterquat C18 unsatd was determined according to OECD Guideline 114 (12 May 1981) and DIN 53015 using a rolling ball viscosimeter.
The test substance did not behave like a Newtonian fluid: the measured viscosity depended on the history of the test item. As the measured viscosity data tend to approach asymptotically an equilibrium value, a lower limit for the viscosity of the test substance was deduced. The dynamic viscosity of MDIPA Esterquat C18 unsatd. is > 17000 mPa s at 20°C.
Reference
Visually the test substance was not homogeneous. Around the ball a corona was observed. In both series of measurements the fall time decreased with each repetition. For a Newtonian fluid constant fall times would have been expected. The measured viscosity depended on the history of the test item. However, as the measured viscosity data tend to approach asymptotically an equilibrium value, it seems to be possible to deduce a kind of lower limit for the viscosity of the test substance. Taking the differences of the two series measurements into account a safe estimation results in: The dynamic viscosity at 20°C of the test item is > 17000 mPa s.
