Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on long-term (chronic) toxicity study data, the test substance is very likely not harmful to aquatic invertebrates.
Key value for chemical safety assessment
Additional information
A GLP guideline study according OECD 211 has been conducted (BASF SE 2017). For the limit test (test concentration of 10 mg/L) a semi-static test design was chosen using a renewal of 3 times per week. Daphnia magna has been exposed for 21 d and the effects on reproduction have been evaluated.
No significant mortality or reduced reproduction were observed in any of the test treatments. Therefore, the data were not sufficient to calculate ECx values for reproduction or mortality.
Since the analytically determined concentrations of the test substance in the test solutions were within the range of ± 20 % of the nominal concentrations, the effect concentration can be expressed relative to the nominal concentration. The LOEC was determined to be > 10 mg/L and the NOEC was determined to be >= 10 mg/L. Therefore, the test substance is very likely not harmful to aquatic invertebrates.
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.
