Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
For Cyclabute short and long-term toxicity information is derived from fish, Daphnia and algae. Short-term toxicity tests for fish, Daphnia and algae are between 1 and 10 mg/l, whereas the long-term values are between 0.1 and 1 mg/L. In view of the long-term information of all trophic levels, for classification and labelling only these data need to be considered. The lowest NOEC value is 0.163 mg/L for algae. The substance is not readily biodegradable this leads to classification as Aquatic Chronic 2 (H411) according to EU CLP (EC 1272/2008 and its updates).
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).
