The structure presented has no structural groups associated with the substance that are indicative of explosivity. As the substance is deemed to be a multicomponent mixture, assessment of oxygen balance values of the smallest and largest theoretical molecules has been undertaken. The results of this indicate that on the basis of oxygen balance, there is a variable propensity towards explosivity. However, based on the guidance, oxygen balance needs not be considered if no structural alerts are present. Based on the information and review of the above substance, it is deemed not to be potentially explosive, based on the chemical structure and oxygen balance values.

Yes

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
The results indicate that on the basis of oxygen balance, there is a variable propensity towards explosivity. However, based on the guidance, oxygen balance needs not be considered if no structural alerts are present. Based on the information and review of the registered substance, it is deemed not to be potentially explosive, based on the chemical structure and oxygen balance values.
Executive summary:

Calculation based on structure and oxygen balance was carried out and determined that the registered substance was not potentially explosive. In accordance with EU-REACH regulations no further study needs to be carried out.

Description of key information

Explosivity.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

There are no chemical groups associated with explosive properties present in the molecule, and the oxygen balance value is not considered to support explosivity.
