Conclusion on classification
Official classification:
Aquatic compartment
According to Regulation (EC) No 1272/2008 Annex VI Table 3.1 and Table 3.2 the substance holds no relevant classification.
Self-classification:
Aquatic compartment
Following CLP the substance is not considered to be acutely hazardous to the aquatic environment.
Following CLP the substance is not considered to be chronically hazardous to aquatic organisms.
Rationale:
According to the criteria outlined in Table 4.1.0(a) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance (CAS 280-57-9) is not to be classified as acutely hazardous to the aquatic environment since the acute toxicity to aquatic organisms (LC/EC50) is greater than 100 mg/L in all cases.
Long-term toxicity data are available for daphnia and algae. Therefore, classification is based on the available chronic data and on acute toxicity data for the trophic level not covered by chronic data (fish).
Chronic toxicity data:
The lowest EC10 is > 1 mg/L (Daphnia, 21d EC10 = 12.3 mg/L; QSAR Toolbox, BASF SE, 2022) indicating that the substance does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (i) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for non-rapidly degradable substances.
Acute toxicity data:
The LC50 determined for fish is > 100 mg/L (Air Products, 2000). The substance is not rapidly degradable, the log Kow is < 4, and the BCF value is < 500. Therefore, according to the criteria outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance is not to be classified as chronically hazardous to the aquatic environment.
Conclusion:
Following CLP, the substance is not to be classified as acutely/chronically hazardous to the aquatic environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
