Conclusion on classification

Bisabolene is a UVCB substance. For a mixture, the acute effect loading level (typically expressed as the EL50) may be used directly for classification. Short-term aquatic toxicity data is available for two trophic levels (algae and daphnia). In an algal inhibition study the 72h EL50 based on growth rate was determined to be > 100 mg/L. In an acute daphnia study the 48h EL50 was determined to be 4.08 mg/L. Since all values are > 1mg/L the substance is not classified for short-term hazards to the aquatic environment according to the CLP Regulation.

 

Adequate chronic toxicity data is not available. Therefore, the long-term hazard has been assessed based on the acute aquatic toxicity data and environmental fate data. Based on the lowest EL50 of 4.08 mg/L and the fact that the substance is not readily biodegradable and has a log Kow of < 4 (range of 6.5 to 7.5 from HPLC determination, it is concluded that the substance is classified Aquatic Chronic 2 (H411) according to the CLP Regulation.
