Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Classification related key information
- Biodegradation in water: inherently biodegradable, not fulfilling specific criteria (EU Method C.4-E)
- Hydrolysis: Half-live of 133h (pH7) (OECD 111)
- Bioaccumulation: log Pow 4.39 (OECD 123)
- Aquatic acute toxicity:
Fish: LC50 (96 h) = 6.72 mg/L (OECD 203)
Aquatic invertebrates: EC50 (48 h) = 9.1 mg/L (EU Method C.2)
Algae: ECr50 (72 h) = 2.7 mg/L (OECD 201)
- Aquatic chronic toxicity:
Fish: No data available
Aquatic invertebrates: No data available
Algae: ErC10 (72 h) = 0.61 mg/L
Classification justification according to CLP
Based on the data above, the substance is considered to be rapidly degradable in the environment (half-live < 16 days and degradation products not classified as hazardous) but bioaccumulation cannot be excluded. Based on the chronic data from aquatic algae (ErC10 (72 h) = 0.61 mg/L) and the acute toxicity to fish (LC50 (96 h) = 6.72 mg/L) the substance has to be classified and labelled as “Aquatic Chronic 2” (H411) according to the Regulation (EC) No 1272/2008 (CLP) and the Regulation (EU) No 1297/2014 (6th ATP).
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.
