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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
- The key ecotoxicity values are as follow:
- Fish: 96h-LC50 was >2.45 mg test material/L (measured, threshold limit test); LC50 = 10.7 mg/L (predicted value from in vitro RTgill-W1 assay)
- Aquatic Invertebrates: 48-h EC50 was 20.5 mg test material/L (measured)
- Aquatic algae: 72-h ErC50 was 3.89 mg test material/L (measured), EC10 = 1.61 mg/L mg test material/L (measured)
- Microorganisms: NOEC = 100 mg/L (nominal)
Based on these results, the lowest acute E(L)C50 is higher than 1 mg/L.
Therefore, the registered substance would not be classified as acute 1 to aquatic organisms in accordance with the classification of the CLP.
Chronic aquatic toxicity data is only available for one trophic level (algae). The EC10 is > 1.0 mg/L and thus based on this data no chronic classification would apply.
However, based on acute aquatic toxicity data for daphnia (EC50 = 20.5 mg/L) and fish (LC50 = 10.7 mg/L) and environmental fate data (not readily biodegradable and log Kow of 3.4), the substance is classified for chronic toxicity as Aquatic Chronic 3.
Additional information
Tests on acute toxicity of the registered were performed for microorganisms and for three trophic levels of aquatic species: fish, algae and crustacea. All tests were conducted under GLP conditions and are considered as valid. For animal welfare reasons, an in vitro assay has been performed and a limit test according to OECD 203.
Results of the in vitro RTgill-W1 assay (ISO 21115) were used to predict an acute fish LC50 value for conclusion on classification regarding CLP.
No effects were seen at the limit concentration used for the OECD 203 test.
The substance has also been tested for Ready biodegradability during two GLP studies following the OECD 301F and OECD 301C guidelines. During these studies, the substance was found to be Not Readily biodegradable.
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.
