Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The test substance showed no toxic effects on Pseudokirchneriella subcapitata during the 72‑hour test period up to the maximum concentration which could be maintained under the conditions of the test (11 µg/L; 100 mg/L loading rate).
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 11 µg/L
Additional information
The test item had no toxic effects on Pseudokirchneriella subcapitata during the 72‑hour test period up to and including the mean measured concentration of 11 µg/L, which is the maximum concentration which could be maintained under the conditions of the test (100 mg/L loading rate).
The test concentration of 11 µg/L was, determined to be the 72‑hour NOEC. This value might even be higher, but concentrations of the test item above the solubility limit in the test water were not tested, in accordance with the test guidelines. The 72‑hour LOEC was higher than 11 µg/L, the maximum concentration of the test item which could be maintained under the conditions of the test.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).
