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, this substance is hydrolytically unstable with hydrolysis rate estimated to be within 1 hr. The hydrolysis products have been identified to be 2-propanol, isostearic acid and titanium dioxide. The physical property of the hydrolysis products were used for evaluating the target substance.
