other: the overall energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C

Screening evaluation

Analysis of the molecular structure of Acid Red 195 revealed that one azo group representing a chemical alert structure for explosive properties was present in the molecule. Calculation of the oxygen balance according to the above mentioned formulas was -134.01 for main constituent 1 and -122.87 for main constituent 2 and therefore higher than the trigger value of -200.

Determination of the exothermic decomposition energy

The curve displayed no exothermic peak 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:
FAT 20042/E TE is considered to be non-explosive.
Executive summary:

FAT 20042/E TE was assessed for explosiveness using the screening procedure 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 molecular structure of FAT 20042/E TE revealed that one azo group representing a chemical alert structure for explosive properties was present in the molecule. The calculated oxygen balance was -134.01 for main constituent 1 and -122.87 for main constituent 2 and therefore higher than the triggervalue of -200. During the determination of the exothermic decomposition energy, the curve displayed no exothermic peak 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 is below 500 °C. Therefore the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008.

Description of key information

FAT 20042/E TE was considered to be non explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

FAT 20042/E TE was assessed for explosiveness using the screening procedure 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

Therefore the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008.

Justification for classification or non-classification

In accordance with Column 2 of section 7.11 of REACH Annex VII, the full study has not been conducted as there are no chemical groups associated with explosive properties present in the substance.
