- Remarks on result:
- not measured/tested
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 20041/D TE is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008.
- Executive summary:
No experimental test data according to EU Method A.14 or comparable methods for Acid Yellow 104 are available.
Considering that explosive properties are associated with the presence of certain chemical groups in the molecule, a screening evaluation was conducted aimed to identify the presence of such reactive groups within the molecular structure harvesting the capability for a rapid high energy release.
Analysis of the chemical structure revealed one azo groups representing a chemical alert structure for explosive properties is present in the molecule. The calculated chemical oxygen balance was 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 FAT 20041/D TE 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 FAT 20041/D TE revealed that one azo group representing a chemical alert structure for explosive properties is present in the molecule.
Calculated oxygen balance was -128.35 and therefore higher than the trigger value of -200.
Determination of the exothermic decomposition energy
The curve displayed one exothermic peak between 280 °C and 350 °C with a total energy release of 168.86 J/g which was considered to represent substance decomposition. 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.
Description of key information
FAT 20041/D TE is considered to be non-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 Yellow 104 are available.

Justification for classification or non-classification
FAT 20041/D TE is considered to be non explosive, hence no classification is required as per Regulation (EC) No. 1272/2008 criteria.
