Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
With high probability acutely not harmful to aquatic algae. No acute toxic effects occur within the range of solubility.
Key value for chemical safety assessment
Additional information
In a study conducted according to OECD guideline 201 (RCC, 2000c) the ErC50 after 72 hours of exposure was determined as > 100 mg/L based on nominal test item concentrations. However, due to the low water solubility, a water accommodated fraction was prepared and the recovery in the highest tested concentration was only 0.0109 mg/L. The water solubility was determined to be < 0.046 mg/L (which was the LOQ in the water solubility study). Therefore the result of the study is considered as: No toxicity in the range of solubility of the test item.
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.
