Conclusion on classification

One short-term toxicity test for daphnia and one aquatic toxicity prediction for algae is available for Cedarwood Texas oil - Cedrol. The 48h EL50 value for daphnia is 11 mg/l, whereas the 72h ErL50 for algae is estimated to be 8.4 mg/L, respectively. Based on the lowest available acute data for algae with an EL50 value of 8.4 mg/L, the substance does not need to be classified for acute aquatic toxicity.


In view of the acute algae result of 8.4 mg/L, the substance being readily biodegradable but the log Kow in the range 4.33 – 6.94, 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 Texas oil - Cedrol needs to be classified for the environment in accordance with the criteria outlined in Annex I of the CLP Regulation (1272/2008/EC) as Category Chronic 2, H411.
