Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC50 (72 h) > 1000 mg/L for Scenedesmus subspicatus based on growth rate (according to OECD 201)
Key value for chemical safety assessment
Additional information
As no study is available for Blankophor TP 0306 (CAS 32257 -57 -1), read-across is performed to a study conducted with the structural analogue CAS 16470 -24 -9. This GLP-study on algae was conducted according to OECD 201. Algae (Scenedesmus subspicatus) were exposed in a dose-response test under static conditions for 96 hours (Ciba-Geigy, BASF SE, 1990). The resulting EC50 (72 h) was > 1000 mg/L based on growth rate.
Thus, for Blankophor TP 0306, no effects on algae are expected.
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.
