Conclusion on classification

One short-term toxicity test for daphnia and one aquatic toxicity study for algae is available for Cedarwood Chinese oil. The EL50 value for daphnia is 2.9 mg/l, whereas the ErL50 and ErL10 for algae are 116 and 9.7 mg/L, respectively. Based on the lowest available acute data for daphnids with an EL50 value of 2.9 mg/L, the substance does not need to be classified for acute aquatic toxicity.

 

As only one chronic value is available (algae), the aquatic chronic classification 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 ErC10 for algae being 9.7 mg/L. In combination with the substance being readily degradable this would not lead to classification. In view of the acute daphnid result of 2.9 mg/L, the substance being readily biodegradable but log Kow in the range 4.33-7.04, 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 Cedarwood Chinese oil 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).
