Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance is acutely harmful to algae.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 87.4 mg/L
- EC10 or NOEC for freshwater algae:
- 40.9 mg/L
Additional information
In a static study following OECD 201 with Desmodesmus subspicatus, the 72h ErC50 was determined to be 87.4 mg/L (ErC10 = 40.9 mg/L) based on nominal concentrations (BASF AG, 1987) without pH adjustment. The non-GLP study does not fulfill all recent validity criteria. The mean specific growth rate and the hazard assessment fulfilled the validity criteria. Since the EC10 and EC50 (mean growth rate) is used for the classification, the test can be used for the assessment of the substance.
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.
