Conclusion on classification

Short-term toxicity results for Daphnia and algae are available for the substance. The 48-h EC50 value for Daphnia is 20.3 mg/L based on ECOSAR calculation. The 72-h ErC50 value for algae is 18.7 mg/L based on ECOSAR calculation. Since the acute EC50 values are >1 mg/L, the substance does not need to be classified for acute toxicity according to EU CLP (EC 1272/2008 and its amendments; Table 4.1.0; a).

Chronic toxicity data are available only for algae. The 72-h ErC10 value for algae is 5.5 mg/L based on ECOSAR calculation.

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 toxicity according to Table 4.1.0, (b) ii.

- The substance is readily biodegradable and has a log Kow value of <4. 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 1272/2008 and its amendments).

GHS:

As the lowest acute toxicity value is >10 but ≤ 100 mg/L, the substance needs to be classified as Acute Cat. 3 (H402: Harmful to aquatic life) according to GHS.
