Description of key information

In analogy of a series of analogue substances,  the substance defined in section 1 is  considered non-biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Although there is no data available concerning ready biodegradability, the substance is very unlikely to be readily biodegradable. Studies on the biodegradability in water of four 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, are available. All studies (for EC 432-690-8, EC 240-521-2, EC 476 -900 -6, and EC 416 -640 -2) demonstrate that the test substances are not readily biodegradable in the available studies.
