Description of key information

With high probability acutely not harmful to algae, no toxic effects occur in the range of water solubility.

Key value for chemical safety assessment

Additional information

In an algae study (72 h) according to OECD 201 no inhibition of algae growth, expressed as biomass and growth rate was observed at the only tested concentration of 100 mg/L nominal. Since the lowest measured concentration of 12 µg/L (at test ending) exceeded the water solubility of the test item (about 1 µg/L, according to CIBA-GEIGY study 646536, 1997), the substance is not considered to be harmful to aquatic algae.
