Comparing the chemical structures of the IDHA chelate it is apparent that they are closely related to each other. The chelating agent of the target substances and as well other IDHA chelates is iminodisuccinic acid (IDHA, known as D,L-Aspartic acid N-(1,2-dicarboxyethyl) tetrasodium salt) which is a pentadentate ligand. IDHA binds a central atom through one amine-, and four carboxyl- groups providing free electron pairs of nitrogen and oxygen atoms, respectively. Calcium is the central atom of coordination complexes of Ca(2Na)IDHA chelate.
All IDHA chelates are solids with comparable molecular weights and density. They are substances with low volatility since they have vapour pressures lower than 500 Pa and boiling points above 150°C (ECHA guidance R.7C, 2014). The chelates are highly soluble in water that is in agreement with the negative logPow values. The substances are non-flammable, non-explosive and do not possess oxidising properties (on basis of the chemical structure of chelates, they are incapable of reacting exothermically with combustible materials).
Taking into account information above and fact that the only difference between the target substance Ca(2Na)IDHA and the source substance is presence of calcium (Ca) cation instead Cu+ cations, it could be concluded that Ca(2Na)IDHA also does not possess oxidising properties.

Conclusions:

Copper chelate Cu(II) IDHA has no oxidizing properties in accordance with test A.17 criteria.

Executive summary:

Oxidising properties of Cu(II)IDHA were determined according to EU Method A. 17 ( Frączak, 2011) in compliance with GLP. In the preliminary test, it was not clearly indicated if the substance has oxidising properties. Therefore, it was necessary to go to the full test. In the train test, the maximum burning rate of the path with cellulose was smaller than the maximal burning rate of the reference mixture. In conclusion, the test substance has no oxidizing properties.

Interpretation of results:

GHS criteria not met

Conclusions:

Chelate Fe(III)IDHA does not have oxidising properties according to the UN O.1. test criterion by the ADR/RID regulations. 

Executive summary:

The test of the oxidising properties has been carried out by a method accredited in accordance with the UN O.1: Test for oxidizing solids published in “Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Fifth revised edition, New York and Geneva, ST/SG/AC.10/11/Rev.17.”

The determination procedure consists in initiating ignition of samples which are formed into cones and constitute a mixture of the material being tested and a combustible material (cellulose) at a mass ratio of 1:1 and 4:1 by means of a glowing resistance wire of an igniter and measuring their burning time. The results obtained relate to the determined burning times of standard mixtures of potassium bromate and cellulose at mass ratios of 3:7, 2:3 and 3:2.

The average burning time for the mixture of Chelate Fe(III) IDHA and cellulose (at both mass ratios) is much longer than the average burning time for the mixture of potassium bromate and cellulose at a mass ratio of 3:7. Chelate Fe(III)IDHA does not have oxidising properties according to the UN O.1. test criterion by the ADR/RID regulations.
