Description of key information
No data is available for the substance itself. The value has been read across from a structurally similar substance (C10 alkyl chain with CAS no. 7396-58-9). The auto ignition temperature of the structurally similar substance has been measured to be 252 °C. The conclusion is that the substance registered (C12-18 alkyl chain) has a similar auto ignition temperature of 252 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 252 °C
Additional information
