Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The water solubility limit has been selected as starting point for the risk assessment. The assessment factors are based on the presence of short-term tests on three trophic levels and the availability of long-term studies in daphnia and algae. For PNECs for soil and sediment the equilibrium partitioning method has been used with K- values based on the logKoc of 6.0 (maximum value in EUSES). The PNEC for secondary poisoning is based on the NOAEL from the 90-day oral toxicity study with a factor of 90 to extrapolate from a sub chronic to chronic exposure.

Conclusion on classification

In none of the acute aquatic toxicity tests performed on fish, daphnia and algae, an LC50 or EC50 could be achieved within limits of solubility. In the daphnia reproduction the NOELR is 100 mg/L. In presence of adequate data on chronic toxicity and based on the fact that the substance is inherently biodegradable, no classification of the substance for acute and/or chronic aquatic toxicity according to CLP (Regulation EC No 1272/2008) is considered.
