Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 for waste-water treatment is 3 mg/L based on the IC50 of 300 mg/L obtained in the activated sludge respiration inhibition test and an assessment factor of 100. No long-term studies on aquatic organisms are available and thus PNECs for aqueous environment were derived by the assessment method based on acute aquatic toxicity data. PNECs for sediment and soil were derived by applying the partitioning method. The substance has a low potential for bioaccumulation and its hazards for predators via the food chain are not anticipated.
Conclusion on classification
The substance was tested for three trophic levels in the aquatic environment using acute test design and the most sensitive species was Fish showing a LC50 of 45 mg/L. The substance is considered non-biodegradable. Based on these results, the substance will not be classified for chronic or acute aquatic toxicity hazards for CLP.
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.
