Conclusion on classification

Using two well-established prediction methods (OECD Toolbox v3.4.0.17 and ECOSAR v2.0), 4 -isopropyl benzaldehyde was predicted to have a 48-hr daphnid L(E)C50 of 1.17 and 3.16 mg/L respectively and a 72(96)-hr algae ErC50 of 15.1 and 2.03 mg/L respectively. A published experimental fish 96h LC50 value of 6.62mg/L is available.


Since all EC50s are > 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 not available. Therefore, the long-term hazard has been assessed based on acute aquatic toxicity data (EC50 >1 mg/L) and environmental fate data (readily biodegradable and measured log Kow 2.8). Since the substance is readily biodegradable and has a log Kow of < 4, the substance is not classified for long-term hazards to the aquatic environment under EU CLP.
