- Conclusions:
- Disperse Red 086 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.
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
Screening evaluation
Analysis of the molecular structure revealed, that no chemical alert structures are present in the molecule. Calculation of the oxygen balance according to the above mentioned formula is -189.37 and therefore higher than the trigger value of -200.
Determination of the exothermic decomposition energy
The curve displayed two exothermic peaks. Peak 1 between 110 and 145 °C with an energy release of 47.97 J/g and Peak 2 between 250 and 350 °C with an energy release of 183.33 J/g. While the second peak is considered to represent substance decomposition energy, the reason for energy release of peak 1 is unknown. As a result, both peaks of energy release are below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.
Description of key information
Analysis of the chemical structure revealed 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.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
Disperse Red 086 is considered to be not explosive, hence it does not warrant classification according to the Regulation (EC) No. 1272/2008.
