Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Toxicity to aquatic algae: Growth rate and yield: EC50(72h)/ LOEC(72h) > 100 mg/L, NOEC(72h)≥ 100 mg/L for Desmodesmus subspicatus (OECD 201, GLP, static)
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
There is a Klimisch 1 OECD 201 study available, indicating that the test item does not need to be classified as hazardous to the aquatic environment. This is based on NOEC, LOEC and EC50 values (growth and yield) ≥ 100 mg/L (NOECs) and > 100 mg/L (LOECs, EC50s), respectively. There is no indication given that the results are not reliable, the data requirements according to REACh Annex VIII are met and no need for further testing was identified.
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.
