Additional information

The long-term toxicity of diethanolamine on aquatic invertebrates was assessed in a semi-static study conducted according to the draft EEC guideline XI/681/86 "Prolonged toxicity study with Daphnia magna: Effects on reproduction" (BASF AG, 1992) following GLP and with analytically verified test concentrations. The test solutions were exchanged three times per week (semi-static conditions). The effect values were recalculated using ToxRat Professional v2.10. The EC10 after 21 days of exposure based on reproduction was determined to be 1.05 mg/L (nominal).


It can be concluded that long-term effects on aquatic invertebrates are not to be expected.
