Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
One reliable study is available for the registered mixture. The mixture exhibits an ErC50 for freshwater algae higher than 100 mg/L and a NOErC of 25 mg/L based on growth rate inhibition.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 25 mg/L
Additional information
The toxicity to aquatic algae was studied according to OECD TG No. 201 and Test Method C.3 from Commission Regulation (EC) No. 440/2008 under GLP¨compliance. All validity criteria were met and therefore the test can be considered to be valid.
The following values were determined:
NOEC Growth Rate and yield = 25 mg/L
EC10 Growth rate= 24 mg/L
EC 50 Growth rate > 100 mg/L
EC 50 Yield = 85 mg/L
These results were assessed to be suitable for chemical risk assessment, PBT assessment and classification and labelling purposes.
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.
