Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Three studies assessing aquatic toxicity at three different trophic levels (fish, aquatic invertebrates and algae) are available.
In a first study, the toxicity to algae was assessed according to OECD 201. The ErC50 and ErC10 values (growth rate) derived for algae were 38.1 mg/L and 19.2 mg/L, respectively. In a second study, the short-term toxicity of the test item to Daphnia was evaluated according to OECD 202. The EC50 value obtained for Daphnia was >100 mg/L. The short-term toxicity to fish was determined in a limit test. The treshold concentration evaluated was 38 mg/L, which corresponds to the lowest EC50 value available for other trophic levels, Daphnia and algae. No mortality or other effects were observed at this treshold concentration, hence it can be concluded that fish is not the most sensitive species and that the LC50 is >38 mg/L.
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
