Screening evaluation

Analysis of the molecular structure revealed that one azo-group representing a chemical alert structure for explosive properties is present in the molecule.

The oxygen balance was calculated to be -169.63 and therefore higher than the trigger value of -200.

Determination of the exothermic decomposition energy

The curve displayed one exothermic peak between 230 and 320 °C with an overall energy release of 313.23 J/g. 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.

Interpretation of results:
GHS criteria not met
Conclusions:
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.
Executive summary:

No experimental test data according to EU Method A.14 or comparable methods for Disperse yellow 114 are available. Hence an expert judgment based on the screening procedure as described in below mentioned guidelines was conducted:

- 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 revealed one azo-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 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.

Additional information

Justification for classification or non-classification

Based on the screening evaluation, the test substance is considered to be non-explosive. Hence no classification is warranted as per the CLP (1272/2008) regulation.
