Additional information
Conclusion on classification
Short-term toxicity results for fish, Daphnia and algae are available for the substance. The 96-h LC50 value for fish is 32 mg/L, the 48-h EC50 value for Daphnia is 78 mg/L, and the 72-h ErC50 value for algae is 58 mg/L. Since the acute toxicity values are >1 mg/L, the substance does not need to be classified for acute toxicity according to EU CLP (EC No. 1272/2008 and its updates: Table 4.1.0; a).
Chronic toxicity data are available only for algae. The 72-h ErC10 value is 8.8 mg/L. According to EU CLP Figure 4.1.1, the chronic classification has to be determined based on the chronic value for algae according to Table 4.1.0, (b) ii, as well as the lowest acute value available for fish and Daphnia according to Table 4.1.0, (b) iii, and the most stringent outcome should be leading:
- The substance is readily biodegradable and has a chronic toxicity value of >1 mg/L. Based on this information, the substance does not need to be classified for chronic toxicity according to Table 4.1.0, (b) ii.
- The substance is readily biodegradable and has a derived BCF of <500 L/kg. Based on this information, the substance does not need to be classified for chronic toxicity according to Table 4.1.0, (b) iii.
Overall: It can be concluded that the substance does not need to be classified for environmental hazards according to EU CLP (EC No. 1272/2008, and its amendments).
GHS: As the lowest acute toxicity value is >10 but ≤ 100 mg/L, the substance additionally needs to be classified as Acute Cat. 3 (H402).
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).
