Additional information

Conclusion on classification

CLP:

Short-term toxicity results for fish, Daphnia and algae are available for the substance. The 96-h LC50 value for fish is 130 mg/L, the 48-h EC50 value for Daphnia is 33.1 mg/L, and the 72-h ErC50 value for algae is 56.7 mg/L. Since the acute toxicity values are >1 mg/L, the substance does not need to be classified for acute toxicity according to Regulation 1272/2008/EC (CLP; Table 4.1.0; a).

Chronic toxicity data are available only for algae. The 72-h NOErC value is 13.7 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) i, 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 not 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) i.

- The substance is not readily biodegradable, and has an acute toxicity value of > 10 but ≤ 100 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 3 according to Table 4.1.0, (b) iii.

Overall, it can be concluded that the substance needs to be classified as Chronic Cat. 3 (H412) according to Regulation 1272/2008/EC (CLP, 2014).

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) according to GHS.
