EC number: 309-304-0 | CAS number: 100208-97-7
In the temperature range of 100 – 130 °C a small endothermic effect can be observed, which is followed by two exothermic effects in the temperature ranges of 210 – 310 °C and 320 – 450 °C, with an overall decomposition energy of approximately -110 J/g.
Table 2: Results of the DSC-measurements
Sample weight / mg
Start of effect / °C
+20 (endothermic)-10 (exothermic)-90 (exothermic)
+30 (endothermic)-50 (exothermic)-60 (exothermic)
Due to the decomposition energy being below the threshold of -500 J/g, further tests for explosive properties did not have to be performed.
In the DSC-measurements the test item Leuco Sulfur Blue 15 showed two exothermic effects in the temperature ranges of 210 – 310 °C and 320 – 450 °C, with an overall decomposition energy of approximately -110 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.
According to the results of the test on thermal stability, the test item is classified as following:
UN Transport Regulation: The test item does not have to be classified as explosive substance in class 1 according to the UN Transport Regulation.
GHS (CLP Regulation EC 1272/2008: Annex 1: 2.1): The test item does not have to be classified as explosive substance according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.1, respectively.
Regulation EC 440/2008 and Directive 67/548/EEC: The test item has no explosive properties according to the Regulation EC No. 440/2008 Method A.14. Explosive Properties.
