Conclusions:
In summary, analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore, the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.
Executive summary:

No experimental test data according to EU Method A.14 or comparable methods for Disperse Red 086 are available. Considering that explosive properties are associated with the presence of certain chemical groups in the molecule, a screening evaluation can be conducted aimed to identify the presence of such reactive groups within the molecular structure harvesting the capability for a rapid high energy release.

According to CLP Regulation examples of groups which may indicate explosive properties are:

- C-C unsaturation (e.g. acetylenes, acetylides, 1,2-dienes);

- C-Metal, N-Metal (e.g. Grignard reagents, organo-lithium compounds);

- Contiguous nitrogen atoms (e.g. azides, aliphatic azo compounds, diazonium salts, hydrazines, sulphonylhydrazides);

- Contiguous oxygen atoms (e.g. peroxides, ozonides);

- N-O (e.g. hydroxyl amines, nitrates, nitro compounds, nitroso compounds, N-oxides, 1,2-oxazoles);

- N-halogen (e.g. chloramines, fluoroamines); - O-halogen (e.g. chlorates, perchlorates, iodosyl compounds).

Analysis of the above depicted molecular structure revealed, that no such chemical alert structures are present in the molecule.

Calculation of the oxygen balance according to the above mentioned formula is -184.13 and therefore slightly higher than the trigger value of -200.

Determination of the exothermic decomposition energy;

In order to assess if the substance Disperse Red 086 possesses the potential to rapidly release huge amounts of energy a thermal analysis (Differential Scanning Calorimetry) has been performed at the Analytical Department Huntsman Textile Effects (Germany) GmbH. The results of the measurement are shown in Annex 1. The curve displays one exothermic peak between 199 and 255 °C with a total energy release of 93.95 J/g. As a result, the overall energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.

Summary and Conclusion:

In summary, analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore, the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.

Justification for classification or non-classification

Disperse Red 86:1 is considered to be not explosive, hence it does not warrant classification as per the Regulation (EC) No. 1272/2008.
