Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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 all three trophic levels (daphnia, algae and fish). A short-term daphnia study is available for Melonal which gave a 48hr EC50 of 2.4 mg/L based on mean measured concentrations. In the absence of experimental data, valid QSAR models have been used to assess toxicity to algae and fish. The predicted 72(96)hr algae EC50 values range from 4.3 to 11.9 mg/L and the predicted 96hr fish LC50 values range from 2.3 to 7.6 mg/L. Since all EC50 values are > 1mg/L the substance is not classified for short-term (acute) 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 and <= 10 mg/L) and environmental fate data (readily biodegradable and log Kow 3.4). Since the substance is readily biodegradable and has a log Kow of < 4, the substance is not classified for long-term (chronic) hazards to the aquatic environment under EU CLP.

According to the old DSD regulation, Directive 67/548/EEC, the substance would be classified as R51/53 based on the EC50 values of >1 and <=10 mg/L and log Kow of > 3.
