Administrative data
Link to relevant study record(s)
- 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.
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- 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.
