Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
48 h, EC50 (Daphnia magna): > 0.357 mg/L (geometric mean measured;
solubility limit of the test item in the test medium, corresponding to a
nominal loading rate of 100 mg/L)
72 h, NOEC (Raphidocelis subcapitata): 0.126 mg/L (mean measured;
solubility limit of the test item in the test medium, corresponding to a
nominal loading rate 100 mg/L).
Aquatic chronic toxicity
72 h, EC50 (growth rate)(Raphidocelis subcapitata): >0.126 mg/L (mean measured; solubility limit of the test item in the test medium, corresponding to a nominal loading rate 100 mg/L).
Biodegradation
Not readily biodegradable: 10.8 % after 28 days (OECD 301 D)
Partition coeficient:
Log Pow < -0.4 at 20 °C.
Classification, Labelling, and Packaging
Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for
classification purposes under Regulation (EC) No 1272/2008. The test
substance was found to be not readily biodegradable under the test
conditions. The 48-h EC50 for Daphnia magna was determined to be > 100
mg/L (nominal). In the 72-h growth inhibition study the test item had
not any significant toxic effects on the test system at the tested limit
concentration of 100 mg/L (nominal). As the registration substance has a
log Pow < 4 (< -0.4 at 20 °C), classification as long term (chronic)
aquatic toxicity category 4 is not considered. Based on these results,
the substance is neither classified as short term (acute) aquatic
toxicity nor classified for long term (chronic) aquatic toxicity
according to Regulation (EC) No 1272/2008 (CLP) as amended for the
twelfth time in Regulation (EU) No 2019/521.
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.
