Conclusion on classification

For daphnia and algae an experimental study is available for the substance. Fish acute data were concluded via read across to Fatty acids, C16-18 and C18-unsatd., Me esters, epoxidized, the LL50 (96h) was > 100 mg/L. The 48h EL50 value for daphnia also exceeded the max solubility at a loading rate of 100 mg/L, whereas the 72h ErL50 for algae is also exceeding max solubility at a loading of 100 mg/L. Based on the lowest available acute data for fish, daphnids and algae, 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. For algae the 72h-ErL10 for growth rate inhibition was 39 mg/L and the substance is not readily biodegradable. This would not lead to Chronic classification.

In view of the acute fish, daphnid and algae result exceeding solubility at 100 mg/L loading, the substance not being readily biodegradable and the log Kow in the range 3.7 – 6.2, the substance does not have to be classified for long term aquatic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) iii of CLP. Since the NOELR for algae is > 1 mg/L, also the Safety net classification (category Chronic 4) would not apply, resulting in no Chronic classification.

Overall, it can be concluded that the substance does not need to be classified for the environment in accordance with the criteria outlined in Annex I of the CLP Regulation (1272/2008/EC) and its amendments.
