Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Acute ecotoxicity tests have been conducted with the test item with fish, Daphnia and algae. Daphnia were found to be the most sensitive species and the EC50 result from this study is therefore used to derive the aquatic PNECs. As no terrestrial or sediment toxicity data are available, PNECs for these compartments are derived using equilibrium partitioning. The substance is not considered to be a hazard for the air compartment and therefore a PNEC air is not derived. The substance is not expected to cause toxic effects if accumulated and therefore a secondary poisoning assessment has not been conducted.

Conclusion on classification

The lowest EC50 value for the test item is 0.2 mg/L, for Daphnia. As this result is <1 mg/L, the substance is assigned a classification of Aquatic acute category 1. As the substance is not readily biodegradable, a classification of Aquatic chronic category 1 is also assigned. Based on a lowest EC50 >0.1 <1 mg/L, acute and chronic M factors of 1 are assigned. The only chronic data available are an algal NOEC of 0.094 mg/L and an EC10 of 0.15 mg/L (growth rate). Based on the algal NOEC the same chronic classification and M factor would be assigned.
