Conclusion on classification

Environmental classification and labelling of a substance is generally based on data from short-term aquatic toxicity results, the ready biodegradability of the substance and an experimentally determined BCF (or if absent the measured octanol/water partition coefficient). Available adequate chronic toxicity data is also relevant for the assessment of long-term aquatic hazards (Regulation 286/2011/EC).


Short-term aquatic toxicity data is available for two trophic levels (daphnia and algae). The lowest short-term L(E)C50 is for daphnia: the 48-hour EC50 is 55 mg/l. Since the EC50 is > 1mg/L the substance is not classified for short-term hazards to the aquatic environment according to the CLP Regulation 1272/2008/EC.


Chronic aquatic toxicity data is only available for one trophic level (algae). Therefore, the long-term hazard has been assessed based on both:


a) The chronic aquatic toxicity data for algae (72 hr ErC10 = 21 mg/l), which results in no chronic classification because the value is > 1 mg/L, and


b) The acute aquatic toxicity data for daphnia (EC50 =55 mg/L) and environmental fate data (readily biodegradable but failing the 10d window and log Kow of 3.5 and 4.0, 2 main peaks). The log kow values are assigned respectively to 3-pentyltetrahydro-2H-pyran-4-yl acetate (concentration range 50 -70%) and nonane-1,3-diyl diacetate (concentration range 20 -30%). Given that the 2ndcomponent meets the chronic classification criterion of Log Kow >= 4.0 and the substance as a whole is not considered as readily biodegradable, Jasmonyl is classified Chronic 3, and classifying according to the most stringent outcome.


Thus it is concluded that the substance is classified Aquatic Chronic 3 (H412) according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.


Under the old DSD regulation the substance would be classified as R52/53 (harmful to aquatic organisms and may cause long-term adverse effects in the aquatic environment) based based on the EC50 values of >10 and < 100 mg/L and log Kow of > 3 (both main components).
