Conclusion on classification
Short-term toxicity tests for Daphnia and algae are available for the substance. The EC50 value for Daphnia is 0.33 mg/l, whereas the ErC50 for algae is 0.28 mg/L. Based on the lowest available concrete acute data for algae the substance needs to beassified for acute aquatic toxicity according to Table 4.1.0 (a) of EU CLP, resulting in Aquatic Acute Category 1 and H400 classification.
Only a chronic algae value is derived: 0.12 mg/l. Based on this EC10 and the substance is readily biodegradable the substance receives Chronic Cat. 3. In absence of other chronic information the chronic classification needs to be derived both from acute and long-term information and taking the lower value for classsification and labelling. In view of the acute Daphnia value (being the other trophic level) and the log Kow > 4, the substance needs to be classified for long-term aquatic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) iii of CLP, resulting in Aquatic Chronic Category 1 and H410 classification.
Overall, it can be concluded that Cedryl acetate needs to be classified as Aquatic Acute 1 and Aquatic Chronic 1 (H400 and H410) in accordance with the criteria outlined in EU CLP (EC No. 1272/2008/EC 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).
