Conclusion on classification
Short-term toxicity tests for algae and Daphnia are available for the substance. The EC50 values for both algae and Daphnia are between 10 and 100 (32 mg/L for algae and 17.1 mg/l for Daphnia). Based on the lowest available acute data for Daphnia with an EC50 value of 17.1 mg/L, the substance does not need to be classified for acute toxicity.
As one chronic value is available, for algae, the chronic C&L needs to be derived on both chronic and acute toxicity data and the most stringent outcome needs to be taken into consideration.
The only chronic available value is the ErC10 of algae being 16.7 mg/L. Based on this, the substance does not need to be classified for chronic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) ii of the CLP Regulation. Then the acute data of the other trophic level needs to be taken into account. The EC50 for Daphnia is 17.1 mg/L, the substance is not readily biodegradable and its log Kow is ≥4 (4.3). In view of the acute result of between 10 and 100 mg/L, the substance needs to be classified for chronic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) iii, resulting in Chronic 3. Overall, it can be concluded that the substance needs to be classified as Chronic 3, H412, according to CLP (EC 1272/2008 and its amendments).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
