Description of key information

Two separate TGD-approved handbooks report that the susbtance has an auto ignition temperature of 399°C to 455.6°C

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
425 °C

Additional information

Data are available for the two constituents. It is concluded that the self-ignition temperature for the reaction mass will be in the same range as the two constituents.


Only one reliable figure has been identified for the autoignition temperature of ethanol.


Information regarding auto flammability of IPA was sourced from two separate handbooks. CRC Handbook of Chemistry and Physics (81st Ed.) and Merck Index: An Encyclopedia of Chemicals, Drugs, and Biologicals (14th Ed.), which are known to contain peer-reviewed data of Klimisch-2 reliability report that the substance has an auto ignition temperature of 399°C and 455.6°C, respectively. This value is above boiling point of 82.5°C, and represents the lowest temperature at which vapours of IPA will spontaneously ignite in a normal atmosphere without an external source of ignition.
