Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 941-784-2 | CAS number: -
Explosiveness
Administrative data
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: Well documented expert statement
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- The screening procedure is 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 structures associated with explosive properties are present in the molecule
- Parameter:
- other: Oxygen balance
- Value:
- -170.1
- Remarks on result:
- other: slightly 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 with a total energy release of about 548.31 J/g. As a result, the overall energy release is slightly above 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 Green 40 is considered to be non-explosive.
- Executive summary:
No experimental test data according to EU Method A.14 or comparable methods for Acid Green 40 are available. Hence an expert judgment based on the screening procedure as described in below mentioned guidelines was conducted:
- CLP Regulation, 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.
Reference
Screening evaluation
Analysis of the molecular structure of the substance revealed, that no chemical alert structures associated with explosiveness are present in the molecule.
Calculation of the oxygen balance according to the above mentioned formula is -170.10 and therefore above the trigger value of -200.
Determination of the exothermic decomposition energy
The curve displayed one exothermic peak between 220 and 290 °C with an energy release of 43.9 J/g. As a result, energy release is far below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.
Description of key information
Acid Green 40 is considered to be not 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 Green 40 are available. Hence an expert judgment based on the screening procedure as described in below mentioned guidelines was conducted:
- CLP Regulation, 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 Green 40 is considered to be non-explosive, hence no classification is warranted as per the criteria set by Regulation (EC) No.1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
