Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Aquatic toxicity:
Three acute experimental studies and two QSAR predictions are available to assess the aquatic toxicity of the registered substance.
The two experimental studies, performed on aquatic invertebrates Daphnia magna and the algae Desmodesmus subspicatus respectively, were not considered reliable due to major methodological deficiencies and/or insufficient information provided on the methodology used. Therefore, QSAR predictions for these endpoints were performed using iSafeRat® High-Accuracy-Quantitative Structure-Activity Relationship (KREATIS, 2019). Toxic effects were predicted on aquatic invertebrates and algae in acute conditions. For daphnids, the 48h-EC50 value was predicted at 0.92 mg/L. For algae, the 72h-ErC50 value was predicted at 2.5 mg/L.
Finally, the experimental study performed on fish Danio rerio was considered reliable (with restrictions). The 96h-LC50 value was determined at 1.9 mg/L, based on initial measured concentrations.
Environmental fate and pathways:
The registered substance is not readily biodegradable (1% biodegradation after 28 days in the OECD 301F key study, 4% biodegradation after 60 days). Thus, in the absence of other studies, the registered substance can be considered potentially Persistent (P) or very Persistent (vP) in the environment. In addition, with a log Kow value at 5.0, the registered substance is considered to be bioaccumulative according to CLP (> 4.0) and potentially B/vB following PBT criteria (> 4.5).
Conclusion on classification
No harmonised classification is available.
Data available:
- Lowest E(L)C50 value < 1 mg/L, more precisely between 0.1 and 1 mg/L (M-factor = 1);
- Not rapidly degradable;
- log Kow > 4.
Classification according to the Annex I of the Regulation (EC) No 1272/2008 (CLP) and GHS Regulation: The registered substance is classified as Aquatic Acute 1 (M-factor = 1) and Aquatic Chronic 1 for the environment.
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.
