Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Principles of method if other than guideline:
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
GLP compliance:
no
Parameter:
other: Presence of chemical structures associated with explosive properties
Remarks on result:
other: no such chemical alert structures are present in the molecule.
Parameter:
other: Calculated oxygen balance
Value:
-156.18
Remarks on result:
other: higher than the trigger value of -200.
Parameter:
other: Exothermic energy
Remarks on result:
other: The curve displays one exothermic peak between 340 and 350 °C with an energy release of 21.18 J/g. As a result, 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 Blue 277 is considered to be not explosive.
Executive summary:

The explosiveness of Acid Blue 277 was assessed using the 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

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

Acid Blue 277 is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008, hence does not warrant classification.
