Conclusion on classification

Short-term toxicity results for Daphnia and algae are available. The 48-h EC50 value for Daphnia is 29.5 mg/L and the 72-h ErC50 value for algae is 25.0 mg/L. Since the lowest acute toxicity value is > 1 mg/L, the substance does not need to be classified as acute aquatic toxic according to EU CLP (EC no. 1272/2008 and its amendments: Table 4.1.0; a).

Chronic toxicity data are available only for algae. The 72-h ErC10/NOErC value is 13.9 mg/L. According to 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 acute value for 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 aquatic toxicity according to Table 4.1.0, (b) ii.

- The substance is readily biodegradable, has a log Kow value of <4 (3.15) and an acute toxicity value of > 10 but ≤ 100 mg/L. Based on this information, the substance does not need to be classified for chronic aquatic toxicity according to Table 4.1.0, (b) iii.

Overall, it can be concluded that the substance does not need to be classified for aquatic toxicity according to EU CLP (EC 1272/2008 and its amendments).

GHS: As the 48h-EC50 for Daphnia magna and the 72-h ErC50 for algae is between 10 -100 mg/L, the substance needs to be classified as Acute Cat. 3 (H402) according to GHS.
