Conclusion on classification

No experimental short-term toxicity tests for algae and Daphnia are available for the substance. Kreatis QSAR worst case predictions resulted in an 48h EL50 value for Daphnia of 7.5 mg/l, whereas the 72h ErL50 for algae is 9.7 mg/L. Based on the lowest available acute data for Daphnia with an EL50 value of 7.5 mg/L the substance does not need to be classified for acute aquatic toxicity according to Table 4.1.0 (a) of CLP.

As no chronic value is available, the aquatic chronic classification needs to be derived on acute toxicity data. In view of the acute daphnid result of 7.5 mg/L, the substance being rapidly biodegradable but a majority of the composition showing 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 2 (H411) classification.

 

Overall, it can be concluded that Petitgrain oil - citrus aurantum 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).
