Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Conclusion on classification
Aquatic acute toxicity
Read-across: 48 h, EC50 (Daphnia magna): >100 mg/L (nominal)
96 h, LC50 (Danio rerio): >100 mg/L (nominal)
72 h, ErC50 growth rate (Desmodesmus subspicatus): >100 mg/L (nominal)
Aquatic chronic toxicity
28 d, NOEC (Cyprinus carpio): >100 mg/L (nominal)
72 h, NOEC (Desmodesmus subspicatus): >100 mg/L (nominal)
Classification, Labeling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data of the substance are reliable and suitable for classification purposes under Regulation (EC) No. 1272/2008. The test item was determined to be not readily biodegradable. In the aquatic tests conducted, the test substance showed no toxic effects on the tested species up to and above the solubility limit of the pure substance. Short-term exposure in Danio rerio resulted in a 96 h LD50 >100 mg/L (nominal) and after long-term exposure (28 d) in Cyprinus carpio a NOEC of >100 mg/L (nominal) was determined. In Desmodesmus subspicatus 72 h EC50 and NOEC of >100 mg/L (nominal) were observed. A study with the read-across source substance showed a 48 h EC50 for Daphnia magna of >100 mg/L (nominal). Based on the results obtained in studies testing up to and above the solubility limit of the substance and taking into account the result with the read-across source substance, the substance is not considered to require classification for short-term (acute) and long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP).
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.
