Additional information
Conclusion on classification
Results are available for fish (96-h LC50 > 464 mg/L after pH-adjustment), invertebrates (48-h EC50 = 218.16 mg/L, Daphnia, magna, read-across to CAS 4245 -51 -9) and algae (72-h ErC50 > 500 mg/L, 72-h ErC10 = 31.3 mg/L; read-across to CAS 4246 -51 -9).The most sensitive species is Daphnia magna.
Official classification regarding environmental hazards
Aquatic compartment
No data were found for the substance concerning Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2.
Self-classification
Aquatic compartment
Following CLP (GHS-EU), the substance is not to be classified as acutely or chronically hazardous to the aquatic environment.
Rationale:
The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is > 1 mg/L.
Chronic data are available for algae, therefore classification is based on the available chronic and acute toxicity data.
- Chronic toxicity data:
Chronic data are available for algae (ErC10 = 31.3 mg/L) 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. Based on the chronic data, the substance is not to be classified as chronically hazardous to the aquatic environment as the lowest EC10 is > 1 mg/L
- Acute toxicity data:
The lowest effect value(LC/EC50) for acute toxicity to aquatic organisms (fish and aquatic invertebrates) is higher than 100 mg/L.
The substance is non-rapidly biodegradable and the log Kow is <4. Based on the acute data, 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. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
