Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

3-h EC50 3-h EC10 |
100 - 1000 mg/L 10 - 100 mg/L |
Key study, Rel 1. |
| OECD TG 211 | Long-term Daphnia | 21-d NOEC | 0.3 mg/l | Key study, Rel 2. The result is based on acute chronic ratio of Florhydral for Daphnia and applied to Floralozone |
In the fish toxicity study the maximum nominal concentration of 0.87 mg/l was used to see if fish were more sensitive compared to Daphnia. The LC50 of fish exceeded the EC50 for Daphnia and therefore for classification and labelling and for the risk characterisation the fish will not be drive the endpoints in these frameworks.
Additional information
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.
