Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
No routine or deliberate environmental releases of the test substance are expected under intended use. This product will only be used in a closed system and no exposure to environmental receptors is expected. Furthermore, test substance is not classified for environmental hazards according to CLP and is not expected to bioaccumulate [molecular weight > 20000 Da., log Kow < 4.0].
Environmental fate and pathways
Degradation
Biodegradation: not readily biodegradable: 5.27% after 28 d (OECD 301B)
Bioaccumulation: Log Kow: 3.62 (EU A.8 Estimation method, 17 °C)
Expert statement: Bioaccumulation is assumed to be low.
Acute aquatic toxicity
- Fish: 96 h, LC50 (Scophthalmus maximus): > 1000 mg/L (nominal)
- Aquatic invertebrates: 48 h, EL50 (Acartia tonsa): > 2000 mg/L (nominal)
- Algae: 72 h, ErL50 (Scenedesmus subspicatus): > 125.5 mg/L (nominal)
Chronic aquatic toxicity
- Fish: 28 d, NOELR (Pimephales promelas): ≥ 12 mg/L (nominal)
- Aquatic invertebrates: 21 d, NOELR (Daphnia magna): ≥ 10 mg/L (nominal)
- Algae: 72 h, NOELR (Scenedesmus subspicatus): 100 mg/L (nominal)
Conclusion on CLP
Data for acute and chronic aquatic toxicity is available for all three trophic levels. The substance is considered to be not rapidly degradable and neither short-term nor long-term toxic effects towards aquatic organisms were observed up to the limit of the water solubility of the substance. Therefore, the substance is not classified and labelled for environmental hazards according to the consolidated version of Regulation (EC) No 1272/2008 (dated: 01.01.2020) and further amendments (ATPs).
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.
