- Executive summary:
The thermal behaviour of test item was assessed using the DSC analysis, according to the OECD guideline 102 and OECD guideline 113. To verify the results of the DSC measurement, three additional measurements with the capillary method were performed in the temperature range of 25 – 300 °C with a heating rate of 10 K/min.
The test item has no melting point up to its decomposition starting at a temperature of approx. 250 °C as determined by differential scanning calorimetry and capillary method. In the DSC-measurements the test item showed two small exothermic effects starting from 90 °C and 220 °C, with an overall decomposition energy of approximately -80 J/g.
Conclusion
In the DSC-measurements the test item showed two small exothermic effects starting from 90 °C and 220 °C, with an overall decomposition energy of approximately -80 J/g. Due to the fact that the energy of the exothermic decomposition was below the threshold of -500 J/g, further tests for explosive properties had not to be performed.
Reference
THERMAL STABILITY
The test item showed two exothermic effects starting from 90 °C and 220 °C, with an overall decomposition energy of approximately -80 J/g.
No. | Sample weight (mg) | Start of effect (°C) | Energy (J/g) |
PN14471 | 6.93 | 90 | -30 (exothermic) |
220 | -60 (exothermic) | ||
PN14472 | 7.37 | 100 | -30 (exothermic) |
220 | -40 (exothermic) |
MELTING POINT - DSC method
The test item showed a broad endothermic effect starting at a temperature of 40 °C and an exothermic effect starting from 250 °C with an average energy release of -50 J/g.
During the heating phase one broad endothermic effect was detected, which cannot be clearly assigned to a melting of the test item.
Results of DSC analysis
No. | Sample weight (mg) | Onset of Effect (°C) | Energy (J/g) | Weight loss (mg) | Atmospheric pressure (hPa) |
PN14226 | 17.11 | 40 | 340 | 4.74 | 997.8 |
250 | -20 | ||||
PN14231 | 13.74 | 50 | 360 | 4.05 | 997.8 |
330 | -80 |
MELTING POINT - capillary method
According to the observations during the tests with the capillary method, the broad endothermic effect starting at 40 °C in the DSC measurements with open crucibles cannot be assigned to the melting of the test item, since the test item did not change its appearance. Since the test item contains 2.5 % water, it can be assumed, that the endothermic effect is caused by the drying of the test item. Starting at a temperature of approx. 290 °C the test item becomes liquid and simultaneously blisters rise. Due to the fact that a sharp exothermic effect was observed in the DSC measurements starting at a temperature of approx. 250 °C, the effect can not be associated with a melting. It can be stated that the test item has no melting point up to its decomposition.

Justification for classification or non-classification
According to the CLP Regulation (EC) No 1272/2008, 2.1.4.2. Screening procedure section, the screening procedure is aimed at identifying the presence of such reactive groups and the potential for rapid energy release. If the screening procedure identifies the substance or mixture to be a potential explosive, the acceptance procedure (section 10.3 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria) has to be performed.
Screening procedure failed to evidence any reason for concern, on the basis that the enthalpy of decomposition of Acid Green 025: test item showed two exothermic effects starting from 90 °C and 220 °C, with an overall decomposition energy of approximately -80 J/g.
In conclusion, the substance can be considered non explosive, according to the CLP Regulation (EC) No 1272/2008.
