Additional information

Diisopropylamine aquatic toxicity profile has been investigated on different levels of the trophic chain: algae, daphnia and fish.

Based on the results obtained it can be conclude that diisopropylamine is harmful to algae and fish with toxicity figures ranging from 20 to 30 mg/L. One long-term toxicity test is also available. In the frame of this study a NOEC of 187 mg/L for the most sensitive endpoint which is the embryonic growth has been determined.

Diisopropylamine showed only a slight effect on the respiration of activated sludge in the conditions of an OECD 209 test with an EC50– 3h which is higher than 100 mg/L.
