Description of key information

The ECOSAR prediction for this endpoint is not reliable. Since acrylates and amides give excess toxicity (see ECOSAR result), a search is performed in the OECD QSAR toolbox for susbtances with several acrylate group (substance of interest has 3 acrylate groups). 8 analogues were found that have experimental toxicity values for growth inhibition test of algae (lowest toxicity value: 1.5 mg/L). Read-across is moreover done to the 'arm' of the substance: VEEA (EC50: 10 mg/L).

Key value for chemical safety assessment

EC50 for freshwater algae:
1.5 mg/L
