Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- other: Expert statement
- Adequacy of study:
- key study
- Study period:
- 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Expert statement
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The screening procedure described in the following guidances was used:
- 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 - GLP compliance:
- no
- Parameter:
- other: Presence of chemical structures associated with explosive properties
- Remarks on result:
- other: no structures associated with explosive properties are present in the molecule
- Parameter:
- other: Oxygen balance
- Value:
- -123.06
- Remarks on result:
- other: higher than the trigger value of -200.
- Parameter:
- other: Exothermic decomposition energy
- Remarks on result:
- other: The curve displays one exothermic peaks 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.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Acid Orange 154 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 Orange 154 are available. Hence the assessment was carried out using the screening procedure described in the following guidances :
- 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 below the trigger value of -200 and the determination of the exothermic decomposition energy demonstrated no energy release up to 350 °C. 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 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 -123.06 and therefore higher than the trigger value of -200.
Determination of the exothermic decomposition energy
The curve displays one exothermic peaks up to 350 °C with a total energy release of 237.30 J/g. This peak is considered to represent substance decomposition. 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.
Description of key information
Acid Orange 154 is considered to be non-explosive.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
No experimental test data according to EU Method A.14 or comparable methods for Acid Orange 154 are available. Hence the assessment was carried out using thescreening procedure described in the following guidances :
- 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 below the trigger value of -200 and the determination of the exothermic decomposition energy demonstrated no energy release up to 350 °C. 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
Acid Orange 154 is considered to be not explosive, hence it does not require classification as per the Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
