Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
One reliable Guideline study is available.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 800 mg/L
- EC10 or NOEC for freshwater algae:
- 800 mg/L
Additional information
The test was performed according to the recommendations of the OECD Guideline 201.
The purpose of this study was to determine the inhibitory effect of the test item on the growth of the fresh water unicellular green alga Scenedesmus subspicatus. Exponentially growing cultures of this algal species were exposed to various concentrations of the test item under defined conditions. The ErC50 (growth rate), ErC100 (growth rate) and NOEC was estimated for a period of 72 hours.
Following results were determined:
72 -h NOEC: 800 mg/l
72 -h EC50: > 800 mg/l
72 -h EC100: > 800 mg/l
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
