Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 toxicity potential of the substance to the aquatic organisms was evaluated by considering available data on the substance. Aquatic toxicity studies include the short-term toxicity studies to fish and to aquatic invertebrates, the toxicity study to aquatic algae and the toxicity to microorganisms. For the derivation of the PNECs the effect levels presented below are considered:
Fish
LC50 (48h) > 1000 mg/L (nominal)
Daphnia
EC50 (48h) > 100 mg/l (nominal)
Aquatic plant
EC50 (7d) >1000 mg/l (nominal)
Microorganisms
EC50 (3h)> 1000 mg/l (nominal)
NOEC (3h) =1000 mg/l (nominal)
Conclusion on classification
The classification of the substance is evaluated based on available acute aquatic toxicity experimental data and on the biodegradation data in water.
Based on the available ecotoxicity studies and on the non biodegradibility of the substance in water, the substance shall not be classified for aquatic toxicity (LC 50 (for fish) and/or EC 50 (for crustacea) and/or ErC 50 for algae or other aquatic plants ≥ 1 mg/L) according to the CLP Regulation (EC) No. 1272/2008.
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.
