Additional information
Conclusion on classification
Experimental acute toxicity data are available only for aquatic invertebrates (Daphnia EC50 > 100 mg/L). The acute toxicity to fish and algae was assessed using QSAR models (fish and algae: L(E)C50 > 100 mg/L). No chronic toxicity data are available.
Official classification regarding environmental hazards
Aquatic compartment
In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is not officially classified.
In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is not officially classified.
Self-classification
Aquatic compartment
Acute (short-term) aquatic hazard
Following CLP, the substance is not to be classified as acutely hazardous to the aquatic environment.
Rationale:
The substance is not to be classified as acutely hazardous to the aquatic environment as the L(E)C50 is > 100 mg/L.
Long-term aquatic hazard
Following CLP, the substance is not to be classified as chronically hazardous to the aquatic environment.
Rationale:
Toxicity data are available only for acute effects on aquatic invertebrates. Therefore classification is based on the available acute toxicity data only.
- Acute toxicity data: The L(E)C50 for fish, aquatic invertebrates and algae is > 100 mg/L, the substance is not rapidly degradable. 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: The substance is not to be classified as chronically hazardous to the aquatic environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
