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 0.64 mg/L, the 48-h EC50 value for Daphnia is 1 mg/L, and the 72-h ErC50 value for algae is 3.4 mg/L. Since the lowest acute toxicity value is ≤ 1 mg/L, the substance needs to be classified as Acute Cat. 1 (H400) according to Regulation 1272/2008/EC (CLP; Table 4.1.0; a).
Chronic toxicity data are available for fish, Daphnia and algae. The 31-d EC10 value for fish is 0.0566 mg/L, the 28-d EC10 value for Daphnia is 0.0146 mg/L, and the 72-h ErC10 value for algae is 1.3 mg/L. According to EU CLP Figure 4.1.1, the chronic classification has to be determined based on the lowest chronic value for Daphnia according to Table 4.1.0, (b) i:
- The substance is not readily biodegradable, and has a chronic toxicity value of <0.1 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 1.
Overall, it can be concluded that the substance needs to be classified as Acute Cat. 1 (H400) and as Chronic Cat. 1 (H410) according to EU CLP (EC No. 1272/2008 and its amendments). The M-factor is 1 for both acute and chronic toxicity.
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).
