+: positive response (flame, blast or deflagration)

-: negative response (nothing or smoke only in a delay of 300 seconds)

Conclusions:
Under the conditions of the study, the auto-ignition temperature of the test material was determined to be 390 ± 10 °C.
Executive summary:

In a non-GLP study conducted in line with EU Method A.15 and DIN 51794, the auto-ignition temperature of hexenyl-3-cis salicylate was determined in a SUR BERLIN oven. The lowest temperature giving a positive effect was 390°C; at a temperature of 380°C no ignition was observed. The auto-ignition temperature of the substance was determined to be 390 ± 10°C.

Description of key information

Auto-ignition temperature was determined to be 390 ± 10°C; study conducted in accordance with EU A.15, DIN 51794; Bolzonella (2011)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
390 °C
