Endpoint:
auto-ignition temperature (liquids)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
Justification for type of information:
According to hydrolysis test results, the hydrolysis rate is estimated to be within 30 minutes. The hydrolysis products have been identified to be triethanolamine and zirconium dioxide.
The target substance was a highly viscous liquid (dynamic viscosity c.a. 27000 mPa.s at 25°C), the vapour pressure was expected to be very low.
Testing would record the results of the key degradation products which are relatively volatile, including triethanolamine.
