Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- other: expert statement
- Adequacy of study:
- key study
- Study period:
- 24 April, 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Justification for type of information:
- None
- Qualifier:
- according to guideline
- Guideline:
- other: According to the screening evaluation recommnded in CLP, UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria as well as REACH
- Version / remarks:
- The screening procedure as described in:
- 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 - Deviations:
- not applicable
- Principles of method if other than guideline:
- Screening evaluation
- GLP compliance:
- no
- Specific details on test material used for the study:
- None
- Key result
- Parameter:
- other: Expert assessment
- Remarks on result:
- negative (not further specified)
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 40278 is considered to be non-explosive.
- Executive summary:
A screening for the explosive properties of FAT 40278 was carried out according to internationally accepted guidelines. Analysis of the molecular structure revealed that one nitro-group representing a chemical alert structure for explosive properties is present in the molecule. The calculated oxygen balance is -170.07 and therefore higher than the trigger value of -200. The determination of the exothermic decomposition energy, revealed a curve displaying one exothermic peak with a total energy release up to 350 °C. 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. 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
Results for screening evaluation:
Analysis of the molecular structure of the substance revealed that one nitro group representing a chemical alert structure for explosive properties is present in the molecule.
Calculation of the oxygen balance according to the above mentioned formula is -170.07 and is therefore higher than the trigger value of -200.
Determination of the exothermic decomposition energy:
The curve obtained from thermal analysis, displayed one exothermic peak with a total energy of 356.37 J/g up to 350 °C with an overall energy release of 313.23 J/g. 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.
Summary and Conclusion:
In summary, analysis of the chemical structure reveals one nitro group representing an alert structure for explosive properties is 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 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.
Description of key information
A screening for the explosive properties of Disperse Blue 077 was carried out according to internationally accepted guidelines. Analysis of the molecular structure revealed that one nitro-group representing a chemical alert structure for explosive properties is present in the molecule. The calculated oxygen balance is -170.07 and therefore higher than the trigger value of -200. The determination of the exothermic decomposition energy, revealed a curve displaying one exothermic peak with a total energy release up to 350 °C. 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.Therefore, the substance is considered to be non-explosive according to 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 Blue 77 has been considered to be non-explosive based on the expert statement, hence does not warrant classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
