Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
The 72-h EC50 based on biomass of algae exposed to the test item was estimated to be 0.16 mg/L.
Key value for chemical safety assessment
Additional information
The toxicity to algae was assessed according to EEC directive 87/302/EEC (1987). The respective NOEbC is <0.16 mg/l. All concentrations are based on measured end concentrations. The compound was directly suspended in the test water. Due to the very low water solubility it is assumed that the compound was not fully solubilized but at least partially present as a suspension.
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.
