Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The PNEC (freshwater) and the PNEC (marine water) and PNEC (intermittent) were estimated using the assessment factor extrapolation method. The EC50 of 5.76 mg/L (corrected for 30% of the registered substance in solution) from the Algae study was used as this was the most sensitive trophic level. The PNEC for sediment (freshwater and Marine) was derived using the using the equilibrium partitioning method since no test was performed on sediment organisms. The PNEC for STP and soil was not derived as the there is no potential for exposure in these environmental compartments.
Conclusion on classification
The substance showed a good potential to biodegrade. The most sensitive acute toxicity test was found to be the acute toxicity to algae, which gave an EC50 5.76 of mg/L. No chronic ecotoxicology tests were performed on the substance. The substance is not classified as hazardous to the aquatic environment, based on EU CLP criteria.
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.
