not explosive

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

One study (Dystar, 1980) was performed on the similar substance 1, by testing the explosive properties of the material under different conditions ( hammer test, dust explosion, exothermic reaction and flammability). Similar substance 1 did not show any explosive properties in any of the different tests.

Direct black 80 could be considered as a not-explosive substance for Read Across with similar substance 1 and based on the above considerations indicated in the attached report.

Justification for classification or non-classification

According to the definition set out in the CLP Regulation (EC 1272/2008) An explosive substance or mixture is a solid or liquid substance or mixture of substances which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to

cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases. Since there are no chemical groups associated with explosive properties present in the molecule and the specific test made on the similar substance 1 gives negative results, the substance is considered not Explosive.
