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.
