According to the REACH Regulation, Annex VII, Column 2, the study does not need to be conducted if there are no chemical groups associated with explosive properties present in the molecule. The screening procedure, aimed at identifying the presence of certain chemical groups in a molecule which can react to produce very rapid increases in temperature or pressure and the potential for rapid energy release, has not evidenced reasons for concern.
Direct Red 079 contains chemical groups associated with explosive properties, but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500 °C. Furthermore this substance is produced and used at the highest level in Europe, transported in ship from outside Europe at various temperature and stoking conditions. Evidences connected to the long experience in handling of the molecule confirm that no explosive properties have never been observed and reported up to now in the usual conditions of production, stock, transport and use.
In conclusion, Direct Red 079 does not meet the criteria to be classify as explosive.
