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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 700-751-0 | CAS number: -
Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
No toxic effects against exponentially growing algal cells were observed at the limit of an effective loading of 100 mg/L.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
Additional information
The results are expressed in terms of Effective Loadings (EL / NOEL) at 72 h of exposure. As the test item consists of a multitude of components and no information about the correlation between molecular weight and the structural formula of the test item are available, Water Accommodated Fractions (WAFs) were used to test effects at effective loading of 100 mg/L and no specific analysis was performed. The content of the test item during the exposure period was verified by DOC determination.
The pH value in the sample containing the test item slightly increased by more than 1.5 pH units. This increase is not regarded as relevant as all validity criteria were met.
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.
