Conclusions:
DTPA-MnNa3 (MnDTPA) does not have the oxidizing properties in accordance with test A.17 criteria.

Executive summary:

Determination of oxidizing properties of DTPA-MnNa3 was performed according to method A.17 Oxidizing properties for solids.

The preliminary test with a mixture of the test substance and cellulose (ratio 2: 1) was performed. The sample charred only in the place of applying the flame of the burner. The sample did not ignite. The burning time of standard mixture was 34 s.

In train test, were used mixtures containing 10% to 90% of cellulose and tested substance. As a reference was used mixtures containing 10% to 90% of cellulose and barium nitrate (V). The maximal burning rate of the reference mixture was 1.82 mm/s. The mixtures od tets substance and cellulose did not burn. DTPA-MnNa3  (MnDTPA) does not have the oxidizing properties in accordance with test A.17 criteria.

 


Description of key information

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Justification for classification or non-classification

As DTPA-MnNa3 chelate does not meet criteria for oxidising properties acc. Method A.17, the classification ans labeling acc Reg 1272/2008 are not required.
