Key value for chemical safety assessment

Additional information

Although there are no data available concerning the acute toxicity to aquatic invertebrates, the substance is considered with high probability acutely not harmful to aquatic invertebrates. Studies are available in order to determine the acute toxicity to Daphnia magna of three members of the category of derivatives of 4,4’-bis(1,3,5-triazinyl-2-yl)amino)stilbene-2,2’-disulfonic acid, each with one anilino and one alkyl amino moiety. All those studies demonstrate that the substances belonging to the category are with a high probability acutely not harmful to aquatic invertebrates.

EC 432-690-8: In a short-term toxicity study of the test substance on Daphnia magna, no toxic effects occurred at the test concentration of nominally 100 mg/L (Clariant 1999). Therefore, the test substance is considered not to be harmful to aquatic invertebrates.

EC 476-900-6: In a short-term toxicity study of the test substance on Daphnia magna, no toxic effects occurred at the test concentration of nominally 100 mg/L (Clariant 2006). Therefore, the test substance is considered not to be harmful to aquatic invertebrates.

EC 416-640-2: In a short-term toxicity study of the test substance on Daphnia magna, no toxic effects occurred at the test concentration of 100 mg/L (Sandoz 1995). Therefore, the test substance is considered not to be harmful to aquatic invertebrates.
