Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Conclusion on classification

In order to compare the experimental results among the different EDTA species the results were related to the H4-EDTA by molecular-weight correction.

Degradation

Biodegradation: not readily biodegradable but ultimately biodegradable under special conditions. 

 

Bioaccumulation

Log Kow: -3.8 at ambient temperature at pH value of 7.2 to 8.7 (OECD 105, 107 and 117)

 

Aquatic acute toxicity

For fish: 96 h, LC50 (Lepomis macrochirus): >100 mg/L under environmental relevant conditions

For aquatic invertebrates: 48 h, EC50 (Daphnia magna): 140 mg/L

For algae/aquatic plant: 72 h, ErC50 (Desmodesmus subspicatus): >100 mg/L

 

Aquatic chronic toxicity (for each species only one key information)

For fish: no data available

For aquatic invertebrates: 21 d, NOEC (Daphnia magna): 25 mg/L

For algae/aquatic plant: 72 h, EC10 (Desmodesmus subspicatus): >100 mg/L

 

Based on the data above, the substance isnot readily biodegradable but ultimately biodegradable under special environmental conditions.The acute aquatic toxicity L(E)C50 values are > 100 mg/L for fish, invertebrates and algae. Therefore, the substance does not need to be classified and labelled as acute aquatic hazardous according to the consolidated version of Regulation (EC) No. 1272/2008 (CLP).

Valid chronic toxicity data are available. The lowest NOEC of 25 mg/L was determined for invertebrates. Therefore, the substance does not need to be classified and labelled for long-term aquatic hazards according to the consolidated version of Regulation (EC) No. 1272/2008 (CLP) and all further amendments.
