Summary and Conclusion:
In summary, analysis of the chemical structure reveals two azo groups representing chemical alert structures for explosive properties are present in the molecule. 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.
Reference
No experimental test data according to EU Method A.14 or comparable methods for Reactive Brown 011 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 two azo groups representing chemical alert structures for explosive properties are present in the molecule.
Calculation of the oxygen balance according to the above mentioned formula is -105.73 and therefore higher than the trigger value of -200.
Determination of the exothermic decomposition energy:
In order to assess if the substance Reactive Brown 011 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 no exothermic peak up to 350 °C. 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.

In summary, analysis of the chemical structure reveals two azo groups representing chemical alert structures for explosive properties are present in the molecule. 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
In accordance with Column 2 of section 7.11 of REACH Annex VII, the full study has not been conducted as there are no chemical groups associated with explosive properties present in the substance. Therefore, no classification is warranted according to CLP (Regulation EC 1272/2008) criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
