Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Even though reproduction is the primary endpoint, parental length turned out to be more sensitive in the OECD 211 study and resulted in a NOEC of 0.53 mg/L.
Key value for chemical safety assessment
Fresh water invertebrates

- Effect concentration:
- 0.53 mg/L
Additional information
One study performed under GLP according to OECD guideline 211 is available. This resulted in a 21d-NOEC for reprodcution of 1.5 mg/L (measured TWM concentration) and a 21d-NOEC for parental body length of 0.53 mg/L (measured TWM concentration) for Daphnia magna.
The study is valid without restriction and can therefore be used for C&L and Hazard- and Risk Assessment.
This is supported by a non-GLP 10 days screening study performed according to OECD 211 which resulted in a 10d-EC10 for reproduction of 6.5 mg/L (measured TWM concentration).
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.
