other: Oxygen balance
Remarks on result:
other: Oxygen balance is -190.69 which is above the trigger value of -200
Parameter:
other: Exothermic decomposition energy
Remarks on result:
other: no exothermic peak up to 350 °C.

Screening evaluation

Analysis of the above depicted 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 -190.69 and therefore above the trigger value of -200.

Determination of the exothermic decomposition energy

In order to assess if the substance Acid Violet 109 possesses the potential to rapidly release huge amounts of energy a thermal analysis (Differential Scanning Calorimetry) has been performed at the Analytical Department Huntsman Textile Effects (Germany) GmbH. The curve displays no exothermic peak up to 350 °C. As a result, no energy release takes place.

Summary and Conclusion

In summary, analysis of the chemical structure 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 no energy release up to 350 °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.

Interpretation of results:
GHS criteria not met
Conclusions:
FAT 20200/C considered to be non-explosive.
Executive summary:

Analysis of the chemical structure of FAT 20200/C 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 no energy release up to 350 °C. Therefore the substance is considered to be non-explosive according to Regulation (EC) 1272/2008 and no further testing is required.

Description of key information

Analysis of the chemical structure of Acid Violet 109 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 no energy release up to 350 °C. Therefore FAT 20200/C is considered to be non-explosive according to Regulation (EC) 1272/2008 and no further testing is required.

non explosive

Additional information

Justification for classification or non-classification

As Acid Violet 109 is considered to be not explosive, classification is not needed according to the EU CLP Regulation (EC) No. 1272/2008.
