Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No toxicity upto 100 mg/L when optimal nutrient concentrations are used was found in a screening study.
Key value for chemical safety assessment
Additional information
Only a screening study is available for toxicity to algae.
The effects in the standard algal test were due to chemical toxicity or to chelation of essential nutrients by the substance. In our opinion, the data now available presents a strong case for the assumption that the growth inhibition in the algal test is indeed due to chelation of essential nutrients rather than chemical toxicity as no toxicity upto 100 mg/L is found when optimal nutrient concentrations are used. These indirect effects may adversely affect the potential for algal growth.
A review of the remaining data relevant to classification indicates that the substance should not be classified for environmental effects.
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.
