Description of key information

Flammability K3EDTA: non-flammable

Key value for chemical safety assessment

non flammable

Additional information

Based on a read-across from a related substance disodium dihydrogen ethylenediaminetetraacetate the substance does not ignite in contact air or water; the result is considered reliable.

Due to calorimetric considerations the organic EDTA anion of sodium salts and the organic EDTA anion of potassium salts should have similar combustion behaviour; therefore a read-across for this endpoint is scientifically justified.
