Screening evaluation

No experimental test data according to EU Method A.14 or comparable methods for Acid Blue 340 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 molecular structure revealed, that no such chemical alert structures are present in the molecule.

Calculated oxygen balance was -168.69 and therefore slightly higher than the trigger value of -200.

Determination of the exothermic decomposition energy

The curve displays one peak between 320 and 350 °C which is considered to represent substance decomposition energy. 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.

Interpretation of results:
GHS criteria not met
Conclusions:
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 Acid Blue 340 are available. Hence an expert judgment based on the screening procedure as described in below mentioned guidelines was conducted:

- CLP, Annex I, Part 2, paragraphs 2.1.4.2 and 2.1.4.3

- Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria

- Technical Guidance Document on the Information Requirements for REACH, Part 2 EWG 1-7, REACH Implementation Project (RIP) 3.3 Phase 2, chapter 7.1.11.3

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.

Additional information

No experimental test data according to EU Method A.14 or comparable methods for Acid Blue 340 are available. Hence an expert judgment based on the screening procedure as described in below mentioned guidelines was conducted:

- CLP, Annex I, Part 2, paragraphs 2.1.4.2 and 2.1.4.3

- Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria

- Technical Guidance Document on the Information Requirements for REACH, Part 2 EWG 1-7, REACH Implementation Project (RIP) 3.3 Phase 2, chapter 7.1.11.3

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

The substance was concluded to be not an explosive based on the expert judgment, hence it does not warrant classification as per the criteria of Regulation (EC) No. 1272/2008.
