Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 key ecotoxicity values are as follow:
- Fish: 96h-LC50 was 24.8 mg test material/L (measured, lowest acute LC50)
- Aquatic Invertebrates: 48-h EC50 was 71 mg test material/L(measured)
- Aquatic algae: 72-h ErC50 was >88 mg test material/L (measured), EC10 = 20 mg/L mg test material/L(measured)
- Microorganisms: EC50 >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.
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.
The substance has also been tested for Ready biodegradability during two GLP studies following the OECD 301F guideline. During these studies, the substance was found to be Readily biodegradable.
Acute hazard classification:
The registered substance would not be classified as acute 1 to aquatic organisms in accordance with the classification of the CLP. Reasoning: all E(L)C50 values are > 1 mg/L.
Chronic hazard classification:
The registered substance would not be classified for chronic toxicity to aquatic organisms in accordance with the classification of the CLP. Reasoning: E(L)C50 values are comprised between 10 and 100 mg/L, the substance is readily biodegradable and has a log Kow < 4.
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).
