Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
With high probability acutely not harmful to aquatic algae.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 180 mg/L
- EC10 or NOEC for freshwater algae:
- 32 mg/L
Additional information
To determine the acute toxicity to aquatic algae a static GLP test was performed using Pseudokirchneriella subcapitata as test organisms in an approach according to OECD guideline 201 (BASF/IPO Institute 2012). After 72 hours of exposure an EC50 > 180 mg/L was estimated while the NOEC was calculated to be 32 mg/L, both related to the endpoint growth rate and the analytically verified nominal concentrations.
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.
