Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Data on the acute toxicity are available for three trophic levels of the aquatic environment.
In a guideline study (OECD 203) using Brachydanio rerio, a LC50 > 58 mg/l based on analytically determined test concentrations was detected (Ciba-Geigy Ltd. (1990)).
A water accommodated fraction using 100 mg/l loading rate was tested in an OECD 202 study with Daphnia magna. No effect in the range of the water solubility of the test substance was observed at test termination after 48 hours (RCC Ltd. (2002)).
In a study according to directive 92/69/EWG, C.3 EEC, the toxicity of the substance to Scenedesmus subspicatus was investigated. An ErC50 (72 h): > 2 mg/L was derived (Ciba-Geigy Ltd. (1995)).
A long-term study in Daphnia was initiated to investigate the effect of the registration item on reproduction (BASF 2015). The NOELR observed in this study was >= 10 mg/L (nominal), i.e. no adverse effects were observed in the range of water solubility of the test substance.
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.
