Endpoint:
auto-ignition temperature (liquids)
Type of information:
other: publication
Adequacy of study:
key study
Study period:
2000
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Qualifier:
no guideline followed
Principles of method if other than guideline:
The method of determination of the auto-flammability temperature was not determined.
GLP compliance:
no
Key result
Auto-ignition temperature:
399 °C
Remarks on result:
other: The atmospheric pressure was not reported.
Conclusions:
The auto-flammability temperature of isopropanol was reported to be 399 °C.
Endpoint:
auto-ignition temperature (liquids)
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Justification for type of information:
A read-across to the main constituent was perfomed to cover this endpoint. As isopropanol as main constituent is the main trigger for the flammability, a read-across to isopropanol CAS 67-63-0 is considered acceptable. Additionally, both isopropanol and the target substance have flash points of 11 and 10 °C, respectively. This information confirmes that the flammability properties of the target substance are based on its main constituent - isopropanol.
Reason / purpose for cross-reference:
read-across source
Key result
Auto-ignition temperature:
399 °C
Remarks on result:
other: The atmospheric pressure was not reported.

Description of key information

The auto-ignition temperature if the test item was covered with a read-across to the main constituent. The auto-ignition temperature for the main constituent was determined to be 399 °C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
399 °C
