Additional information
Reliable acute toxicity tests results are available for freshwater fish (Brachydanio rerio), invertebrates (Daphnia magna) and algae (Desmodesmus subspicatus). The EC50 values for the three organisms were ca. 48.5, 11.6 and >100 mg/L respectively when expressed relative to nominal concentrations used to prepare the test media. A NOEC of 5 mg/L in the daphnia and of > 100 mg/l in the algal test were determined. It is likely that, because of the prolonged test medium preparation phases, the test organisms were predominantly exposed to the hydrolysis products of the substance.
In an activated sludge respiratory inhibition test an EC50 value of > 160 mg/L has been determined in a test conducted according to an appropriate guideline study.
A 14-day LC50 and LC10 value of >1000 mg/kg dry weight have been determined for the effects of the test substance on mortality of Eisenia foetida. It is likely that the test organisms were exposed to the hydrolysis products of the test substance.
Conclusion on classification
Classification according to CLP
The substance is not readily biodegradable and the most sensitive species was Daphnia magna with an EC50 (48 h) of 11.6 mg/L. Thus, the substance has to be classified and labeled as H412 “Harmful to aquatic life with long lasting effects” according to the 2nd ATP of Regulation (EC) No 1272/2008 (CLP).
Classification according to DSD/DPD
The substance is not readily biodegradable and the most sensitive species was Daphnia magna with an EC50 (48 h) of 11.6 mg/L. Thus, the substance has to be classified and labeled as environmental hazard R52/53 “Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment” according to Directive 67/548/EEC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
