Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test substance is with high probability not acutely harmful to aquatic algae. No toxic effects occur within the range of solubility.
Key value for chemical safety assessment
Additional information
A GLP guideline study according OECD 201 has been conducted (LAUS GmbH 2014). Due the low solubility of the test item a limit test has been conducted using a saturated solution with a loading rate of 100 mg/L. No applicable analytical method could be found, therefore, no analytical determination of the test item in the test solutions was made in the final toxicity test.
After 72 h exposure no effects up to the limit of solubility have been observed. Therfore, the EC10 and the EC50 for growth rate and yield were determined to be above 100 mg/L.
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.
