Key result
Remarks on result:
no self ignition observed under the test conditions

An exothermic effect was observed between 250°C and 257°C, with a temperature peak of about 290°C.

The test material, Balsalazide acid does not self-ignite up to 400°C.

Description of key information

The relative self-ignition temperature of Balsalazide acid was determined according to EC Method A.16 and was found not to self-ignite up to 400°C.

Key value for chemical safety assessment
