Description of key information
In a GLP study conducted according to EU Method A.10, EDDS acid was considered "not highly flammable".
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
In a GLP study conducted according to EU Method A.10, the flammability of EDDS acid was examined on six occasions by the application of a flame or hot wire to a strip of the powdered material (250 mm long, 20 mm wide and 10 mm high). The test material ignited briefly, but no flame propagation occurred. EDDS acid is considered 'not highly flammable' according to the test conditions (Gair et al. 2002).
In addition, in a GLP study conducted according to EU Method A.10, trisodium EDDS could not be ignited by a flame (van Helvoirt, 1993e). [Data on trisodium EDDS is considered relevant to use for understanding the potential flammability of EDDS acid, and is acceptable for using as read-across information].
Justification for classification or non-classification
EDDS acid and its trisodium salt were not easily ignited by brief contact with an ignition source in reliable tests and, therefore, would not be classified as flammable solids according to EU CLP or DSD regulations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
