Analysis of the molecular structure revealed, that no such chemical alert structures are present in the molecule.

Calculation of the oxygen balance according to the above mentioned formula is -118.63 and therefore higher than the trigger value of -200.

During the thermal analysis using Differential Scanning Calorimetry, the curve displays one exothermic peak between 200 and 260 °C with a total energy release of 17.75 J/g representing substance decomposition. 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:
The substance is considered to be non-explosive.
Executive summary:

Analysis of the chemical structure of Reactive Blue 050 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.

Description of key information

Reactive Blue 050 is considered to be non-explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Analysis of the chemical structure of Reactive Blue 050 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

Reactive Blue 050 is considered to be not explosive, hence does not warrant classification as per the Regulation (EC) No. 1272/2008
