Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Relative self-ignition temperature:
- 400 °C
- Remarks on result:
- other: The temperature of the oven at which the sample reaches 400°C by self-heating is appointed as the self-ignition temperature of the test substance.
- Conclusions:
- The substance is not self-ignitable. The temperature of the oven at which the sample reaches 400°C by self-heating is appointed as the self-ignition temperature of the test substance.
Reference
Small differences (<20°C) between sample and oven temperature were observed during the performance of the test.
Using a linear increase in temperature of 0.5°C/min, the test substance showed two exothermic reactions. The first exothermic reaction started at an oven temperature of about 150°C. The test substance increased to a maximum temperature of 200°C at an oven temperature of 150°C. The second exothermic reaction started at an oven temperature of about 315°C. The test substance temperature increased to a maximum of 395°C at an oven temperature of 315°C. This second exothermic effect was observed after melting of the test substance (melting temperature of the test substance: see results of the DSC study) and has therefore not to be seen as relevant.
The test substance had melted and changed into a white/gray residue.
Description of key information
The substance is not self-ignitable. The temperature of the oven at which the sample reaches 400°C by self-heating is appointed as the self-ignition temperature of the test substance.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 400 °C
Additional information
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.
