- Key result
- Parameter:
- other: Screening evaluation for presence of chemical structures associated with explosive properties
- Remarks on result:
- other: no such structure is present
- Parameter:
- other: Determination of the exothermic decomposition energy
- Remarks on result:
- other: a total energy release of 218.45 J/g up to 350 °C. As a result the energy release was below a critical trigger level of 500 J/g with the onset of energy release being below 500 °C.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Disperse Red 302:1 is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008.
- Executive summary:
A screening evaluation for the explosive properties of Disperse Red 302:1 was carried out according to internationally accepted guidelines. Analysis of the molecular structure revealed no alerts for explosive properties. The calculated oxygen balance is -199.76 and therefore slightly higher than the trigger value of -200. While the determination of the exothermic decomposition energy, revealed one exothermic peak with a total energy release 218.45 J/g 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 was below 500 °C. 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 Disperse Red 302:1 revealed, that no chemical alert structures associated with explosive properties are present in the molecule.
The oxygen balance was calculated to be -181.22 and therefore slightly higher than the trigger value of -200.
Determination of the exothermic decomposition energy
The curve displayed one exothermic peak with a total energy release of 44 J/g up to 350 °C. As a result the energy release was below a critical trigger level of 500 J/g with the onset of energy release being below 500 °C.
Description of key information
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.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
