Description of key information

No self ignition.

Key value for chemical safety assessment

Additional information

Evidences connected to the long experience in handling and use of the molecule confirm the not spontaneous ignition property.

Moreover, two existing study on a different salification of the substance was considered as supporting information:

The self-ignition temperature of the test item was investigated according to the guideline VDI 2263, sheet 1 (Grewer-Oven). Self-ignition was observed at approximately 200 °C. Due to this result further tests are necessary for the classification therefore another test was conducted according to the UN test N.4, Due to the fact that a negative result was obtained in the test using a 10 cm sample cube at 140 °C the test item has not to be classified in division 4.2 (self-heating substances) and also has not to be classified as “self-heating substance” according to chapter 2.11[1], category 2of the GHS (CLP) regulations.


The evaluation of the similarity between the target substance and the Similar Substance 02 is attached at section 13.
