Conclusion on classification
According to the ecotoxicological results and the biodegradation result, the test item is classified as aquatic acute toxicity cat.2 H401 and aquatic chronic toxicity cat.1. H410.
Short-term E/LC50 values are available for algae (growth rate 72h-EC50 = 1.15 mg/L), daphnia (48h-EC50 = 18.8 mg/L). The lowest EC50 is obtained in the Algal test showing that the substance is toxic to the aquatic organisms.
Additionally, the reaction mass is not readily biodegradable and due to the log Kow <3 there is no tendency to bioaccumulate. Chronic toxicity data are only available for chronic daphnia showing a 21d-ErC10 = 0.041 mg/L
Based on this information, this substance is very toxic to aquatic life with long lasting effects.
This results in a classification of:
Aquatic acute 2, H401
Aquatic chronic 1, H410
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
