- Executive summary:
In the DSC-measurement the absolute value of the energy of the exothermic decomposition of the test item, Dilithium salicylate, was <-500 J/g. Therefore, further tests on explosive properties did not have to be performed.
According to the results of the test on thermal stability, the test item is classified as follows:
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.
Reference
The DSC runs in closed glass crucibles PN14502 and PN14507 are shown in the table below. In the DSC measurement a first endothermic effect was oberserved in the temperature range of 140 to 160 °C. A second endothermic effect was observed in the temperature range 190 to 200 °C. This effect led to an exothermic effect starting at 200 °C with a decomposition energy of -60 J/g. A third endothermic effect was observed in the temperature range of 210 to 250 °C. Subsequently a second exothermic effect was observed starting at 390 °C with an average decomposition energy of –60 J/g.

Due to the absolute value of the decomposition energy being below the threshold of -500 J/g, further tests on explosive properties did not have to be performed.
Description of key information
In the DSC-measurement the absolute value of the energy of the exothermic decomposition of Dilithium salicylate was <-500 J/g. Therefore, further tests on explosive properties did not have to be performed.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
This study was GLP compliant and followed the UN Manual of Tests and Criteria, Part I and OECD guideline 113.
The study was given a reliability rating of 1 (reliable without restrictions).
Justification for classification or non-classification
In the DSC-measurement the absolute value of the energy of the exothermic decomposition of Dilithium salicylate was <-500 J/g. Therefore, further tests on explosive properties did not have to be performed.
According to the results of the test on thermal stability, the test item is classified as follows:
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.
