Conclusion on classification
For algae and daphnid toxicity values, an ECOSAR calculation was performed for Reseda body. The EC50 value for Daphnia is 4.37 mg/l, whereas the EC50 and long-term toxicity for algae are 6.0 and 2.18 mg/L respectively.
Based on the lowest available acute data for daphnia with an EC50 value of 4.37 mg/L the substance does not need to be classified for acute aquatic toxicity according to Table 4.1.0 (a) of CLP.
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 lowest chronic value available is the EC10/NOEC for algae being 2.18 mg/L. In combination with the substance not being rapidly degradable this would not lead to classification according to Table 4.1.0 (b) (i) of CLP. In view of the acute Daphnia result of 4.37 mg/L, the substance not being rapidly biodegradable and the log Kow of 3.6, the substance needs to be classified for chronic aquatic toxicity Category Chronic 2 (H411) according to Figure 4.1.1 and Table 4.1.0, (b) iii.
Overall, it can be concluded that Reseda body needs to be classified as Aquatic Chronic 2 (H411) in accordance with the criteria outlined in Annex I of the CLP Regulation (1272/2008/EC and its amendments).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
