- Specific details on test material used for the study:
- - Trade name: Purasolv EL
- Batch number: 0909001195
- Appearance: Clear colourless liquid
- Purity: 99.83% w/w
- Storage: at room temperature, in the dark under nitrogen
- Expiry date: 2010-09-14 - Key result
- Auto-ignition temperature:
- 430 °C
- Atm. press.:
- >= 1 016.3 - <= 1 024.1 hPa
- 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.
Reference
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).
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
