Description of key information

Three tests were available, the UN 2(a), 2(b) and 2(c)i tests.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

All three tests, viz. the UN gap test (alternative test), the Koenen test and the Time/Pressure test were negative, indicating that GLDA-Na4 has no explosive properties. Although these tests differ from the EU test (EU A14), it was clear that the exothermic heat was 123 J/g, which is below the value of 500 J/g and therefore can be considered non-explosive. Also based on the molecular structure of GLDA-Na4 it is not expected that GLDA-Na4 would have explosive properties. Finally, EU A14 tests carried out with other chelating agents such as DTPA-Na5, EDTA-MnNa2 and EDTA-FeNa) did not show explosive properties either.

Justification for classification or non-classification

Based on the data indicated above, it was concluded that GLDA-Na4 has no explosive properties and as such classification is not warranted.
