Description of key information

EDDS and its trisodium salt do not contain any chemically instable or high energetic groups that might lead to an explosion. 

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

In accordance with column 2 of REACH Annex VII, the study (required in section 7.11) does not need to be conducted as there are no chemical groups associated with explosive properties present in the molecule.

In addition, the explosive properties of trisodium EDDS have been assessed from its molecular formula. According to an Expert statement, trisodium EDDS does not contain any chemically instable or high energetic groups that might lead to an explosion. Therefore, it can be concluded that trisodium EDDS is not explosive (van Helvoirt, 1993f). [Data on trisodium EDDS is considered relevant to use for understanding the potential explosiveness of EDDS acid, and is acceptable for using as read-across information].

Justification for classification or non-classification

As EDDS and its trisodium salt do not contain any chemically instable or high energetic groups that might lead to an explosion, they would not be classified as explosive substances according to EU CLP or DSD regulations.
