1,4-Benzenedisulfonic acid, 2,2'-[1,2-ethenediylbis[(3-sulfo-4,1-phenylene)imino[6-[bis(2-hydroxypropyl)amino]-1,3,5-triazine-4,2-diyl]imino]]bis-, sodium salt (1:6)

Endpoint summary

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.

No data on the biodegradation in sediments, surface water and soil are available for the test item. However, further biotic degradation testing shall be proposed if the chemical safety assessment according to Annex I indicates the need to investigate further degradation of the substance and its degradation products. It is assumed that the test substance is not biodegradable in simulation tests either. Therefore, simulation studies on surface water, sediments and soil are not provided.
