Conclusion on classification
Short-term toxicity tests for algae and Daphnia are available for the substance. The EC50 value for Daphnia is 0.39 mg/l, whereas the ErC50 for algae is between 1 and 10 mg/l (8.2 mg/l). Based on the lowest available acute data for Daphnia with an EC50 value of 0.39 mg/l, the substance needs to be classified as Acute 1 (CLP, 2011: Table 4.1.0-a) and H400.
The lowest chronic available value is the ErC10 of algae being 3.2 mg/L and based on this value in combination with its non ready biodegradability the substance does not need to be classified for chronic toxicity (Table 4.1.0-b).
However, because only 1 chronic endpoint is available (algae), chronic classification also needs to be derived on acute data from the other trophic level. In view of the EC50 of Daphnia being 0.39 mg/l and the fact that the substance is not readily biodegradable and its log Kow is 4.9, 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 1 and H410.
Overall, it can be concluded that Phenafleur needs to be classified as H400/H410 according to Regulation 1272/2008/EC (CLP, 2011) 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).
