Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two acute experimental studies and three QSAR predictions are available to assess the aquatic toxicity of the registered substance.
The experimental studies were not considered reliable due to major methodological deficiencies and/or insufficient information provided on the methodology used. Therefore, QSAR predictions were performed using iSafeRat® High-Accuracy-Quantitative Structure-Activity Relationship (KREATIS, 2019). Toxic effects were predicted on the three aquatic trophic levels (aquatic invertebrates, algae, fish) in acute conditions.
For algae, the 72h-ErC50 value was predicted at 0.43 mg/L. For daphnid, the 48h-EC50 value was predicted at 1.2 mg/L; and for fish, the 96h-LC50 value was predicted at 1.9 mg/L.
Environmental fate and pathways
The registered substance is readily biodegradable (75% biodegradation after 28 days, within the 14-d window based on the OECD 301D key study) and therefore is not persistent in the environment. In addition, with a log Kow value determined experimentally at 3.87, the substance is not considered to be bioaccumulative according to CLP (<4.0) and PBT criteria (<4.5).
Conclusion on classification
No harmonised classification is available.
Data available:
- Lowest E(L)C50 value < 1 mg/L (for algae), more precisely between 0.1 and 1 mg/L (M-factor = 1);
- Rapidly degradable;
- log Kow < 4.
Classification according to the Annex VI of the Regulation (EC) No 1272/2008 (CLP):
The registered substance is classified as Aquatic Acute 1 (M-factor = 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.
