Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 effects of the test item were assessed in freshawater algae (P. subcapitata).
The 72-h ErC50= 0.07 mg/L and 72-h NOEC (growth rate) = 0.011 mg/L based on the measured test item concentration.
The 72-h EyC50= 0.033 mg/L and the 72-h NOEC (yield) = 0.011 mg/L based on the measured test item concentration.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 0.071 mg/L
- EC10 or NOEC for freshwater algae:
- 0.011 mg/L
Additional information
The effects on freshwater algae (P. subcapitata) were assessed according to OECD TG 201 using water accommodated fractions (WAFs) at measured test item concentrations of 0.011, 0.050, 0.079, 0.11 and 0.44 mg/L (geometric mean of measured concentrations over 72-h).
The 72-h ErC50= 0.07 mg/L and 72-h NOEC (growth rate) = 0.011 mg/L.
The 72-h EyC50= 0.033 mg/L and the 72-h NOEC (yield) = 0.011 mg/L.
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.
