Description of key information

Non explosive

Key value for chemical safety assessment

non explosive

Additional information

According to the REACH Regulation (EC 1907/2006), Annex VII, Column 2, the study does not need to be conducted if the organic substance or a homogenous mixture of organic substances 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.

Based on the outcomes of the DSC analysis, decomposition occurs upon water / solvent release and 2 slight endothermic events, starting at 241 °C. The onset of decomposition is at 250 °C and the energy release is 140.2 J/g.

Further considerations

Solvent Red 122 is produced and used at the highest level in Europe, transported in ship from outside Europe under various temperature and storage conditions. Evidences connected to the long experience in handling and use confirm that no explosive properties have never been observed and reported up to now in the usual conditions of production, storage, transport and use.

Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008), Screening procedure section, the screening procedure is aimed at identifying the presence of such reactive groups and the potential for rapid energy release. If the screening procedure identifies the substance or mixture to be a potential explosive, the acceptance procedure (section 10.3 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria) has to be performed.

Screening procedure failed to evidence any reason for concern, on the basis of the thermal behaviour.

In conclusion, the substance can be considered non explosive, according to the CLP Regulation (EC 1272/2008).
