Key result

Auto-ignition temperature:

430 °C

Atm. press.:

>= 1 016.3 - <= 1 024.1 hPa

Three tests were performed, each in triplicate, varying the amount of ethyl lactate solution that was introduced into the auto-ignition chamber. The reported auto-ignition temperature is the lowest temperature at which auto-ignition was recorded (rounded).

Conclusions:

The auto-ignition temperature of PURASOLV®EL (ethyl (S)-lactate) is 430 °C.

Executive summary:

Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of PURASOLV®EL (ethyl (S)-lactate). The test substance is auto-ignitable with an auto-ignition temperature at 1016.3 – 1024.1 hPa of 430 °C.

Description of key information

Ethyl (S)-lactate is auto-ignitable with an auto-ignition temperature of 430 °C (at 1016–1024 hPa).

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

430 °C

Additional information

The atmospheric pressure during the performance of the study was between 1016.3 and 1024.1 hPa. The reported auto-ignition temperature is the lowest temperature at which auto-ignition was recorded (rounded). The unrounded values for the lowest auto-ignition temperature ranged from 434 to 439 °C in three tests. The reported minimum auto-ignition temperature of 430 °C is expected to be valid at the slightly lower standard pressure of 1013.25 hPa as well.
