Conclusion on classification
Classification related key information
Physico-chemical properties and Efate
| log Pow | -3.86 (calculated) |
| water solubility | 400 g/L (literature) |
| Biodegradation | < 60% in 28d (OECD 301B) |
| Bioaccumulation | BCF = 1-2 L/kg (read across) |
Aquatic acute toxicity
For fish: LC50 (96h) | > 100 mg/L (WoE, read across) |
For algae: EC50 (72h) | > 100 mg/L (WoE, read across) |
For crustacea: EC50 (48h) | > 100 mg/L (WoE, read across) |
Aquatic chronic toxicity
For fish: NOEC (35d) | >= 35.1 mg/L (OECD 210, read across) |
For algae: NOEC (72h | > 48.4 mg/L (OECD 201, WoE, read across) |
For crustacea: NOEC (21d) | >= 25 mg/L (OECD 211, read across) |
Classification according to CLP
Based on the data above, edetic acid (CAS No. 60-00-4, H4EDTA) is not considered to be readily biodegradable. No acute aquatic toxicity was observed below 100 mg/L for fish, invertebrates and algae. Valid chronic data are available for all trophic levels showing no effect values below 1 mg/L. Therefore, edetic acid does not need to be classified and labelled as acute or chronic aquatic hazard according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).
