Key result

Parameter:

other: exothermic decomposition energy (J/g)

Value:

51.68

Remarks on result:

other: energy release was below a critical trigger level of 500 J/g

Screening evaluation

Analysis of the molecular structure of the substance revealed, that no chemical alert structures associated with explosive properties are present in the molecule.

Oxygen balance was calculated to be -183.45 and therefore slightly higher than the trigger value of -200.

Determination of the exothermic decomposition energy

The curve displayed one peak at about 180 °C with an energy release of 51.68 J/g. As a result, the overall energy release was below a critical trigger level of 500 J/g and the onset of energy release was below 500 °C.

Interpretation of results:

non explosive

Remarks:

Migrated information

Conclusions:

The substance is considered to be non-explosive.

Executive summary:

No experimental test data according to EU Method A.14 or comparable methods for Disperse Blue 60 are available. Considering that explosive properties are associated with the presence of certain chemical groups in the molecule, a screening evaluation was 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 molecular structure revealed, that no chemical alert structures associated with explosive properties are present in the molecule.

Oxygen balance was calculated to be -183.45 and therefore slightly higher than the trigger value of -200.

During exothermic decomposition energy release test, the curve displayed one peak at about 180 °C with an energy release of 51.68 J/g. As a result, the overall energy release was below a critical trigger level of 500 J/g and the onset of energy release was below 500 °C.

In summary, analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance was 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

FAT 36152/M is considered to be non-explosive, hence no classification for explosiveness is required as per the Regulation (EC) No. 1272/2008 (CLP) criteria.
