Conclusion on classification
Short-term toxicity tests for algae and Daphnia are available. The EC50 values for both algae and Daphnia are between 10 and 100 (36 and 52 mg/L, respectively). Based on the lowest available acute data for algae with an EC50 value of 36 mg/L, the substance does not need to be classified for acute toxicity according to Table 4.1.0 (a) of CLP.
As only 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 in , accordance with Figure 4.1.1 of the CLP.
The only chronic value available is the NOEC for algae being 9.3 mg/L. In combination with the substance being readily degradable, the substance does not need to be classified for chronic toxicity (Table 4.1.0, (b) ii). When taking into account the acute data of the other trophic level, i.e. Daphnia with an EC50 value of 52 mg/L, in combination with the substance being readily degradable and having a log Kow of 2 (< 4), 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).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.
