Conclusion on classification

Short-term toxicity tests for fish, Daphnia and algae are available for the substance. The 96h-LC50 value for fish is 32 mg/L. The EC50 value for Daphnia is 78 mg/L. The ErC50 for algae is 58 mg/L. Since all acute L(E)C50 values are > 1 mg/L, the substance does not need to be classified for acute toxicity (CLP, 2014: Table 4.1.0; a).

The only available chronic value is the ErC10 of algae being 8.8 mg/L. According to CLP Figure 4.1.1, the chronic classification has to be determined based on this chronic value according to Table 4.1.0, (b) ii and based on available acute data according to Table 4.1.0, (b) iii and the most stringent outcome should be leading:

The substance is readily biodegradable. Based on the ErC10 > 1 mg/L, the substance does not need to be classified for chronic toxicity according to Table 4.1.0, (b) ii

Based on the fact that the substance is readily biodegradable and the Log Pow < 4, it 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 Regulation 1272/2008/EC (CLP, 2014).
