Description of key information
Isobutyl-(S)-lactate shows an auto-ignition temperature of 410 °C at 1019.0 to 1019.9 hPa.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 410 °C
Additional information
The auto-ignition temperature of isobutyl-(S)-lactate was tested in a GLP compliant study according to EU method A.15 (Regulation EC 440/2008), DIN Guide 51794 from May 2003 and the IEC standard 79-4, Part 4, Method of Test for Ignition Temperature from 1975, using a commercially available auto-ignition temperature apparatus. Samples were injected into the heated-up test vessel. The occurrence of clearly perceptible flames and/or explosions served as indication for auto-ignition. Preliminary findings indicate an auto-ignition temperature of 420 °C. The main study refined the final temperature to 410 °C at 1019.0 to 1019.9 hPa. Varying across the sample volumes, the ignition was delayed between 10 and 14 seconds. All flames observed were of orange/blue colour.
The value can be extrapolated to the target substance isobutyl-(R)-lactate without restrictions, since being the optical antipode.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
