Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
With high probability acutely not harmful to algae, no toxic effects occur in the range of water solubility.
Key value for chemical safety assessment
Additional information
In an algae study (72 h) according to OECD 201 no inhibition of algae growth, expressed as biomass and growth rate was observed at the only tested concentration of 100 mg/L nominal. Since the lowest measured concentration of 12 µg/L (at test ending) exceeded the water solubility of the test item (about 1 µg/L, according to CIBA-GEIGY study 646536, 1997), the substance is not considered to be harmful to aquatic algae.
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.
