Description of key information

Acute toxicity test was performed according to OECD TG 201 and GLP in a limit test with a EC50 > 100 mg/L.

ECOSAR predicted the long term toxicity on green algae of 2,5,7,10-TETRAOXAUNDECANE (TOU) equal to 625.436 (mg/L). The prediction is reliable since 2,5,7,10-TETRAOXAUNDECANE (TOU) is in the logKow and MW range of the model.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L
EC10 or NOEC for freshwater algae:
625.436 mg/L
