Description of key information

The substance is stable in water.

Key value for chemical safety assessment

Half-life for hydrolysis:
1 yr
at the temperature of:
25 °C

Additional information

Three studies on the hydrolysis in 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 476 -900 -6, and EC 416 -640 -2) demonstrate that the test substances are stable (hydrolysis < 10 %) at pH 4, 7 and 9 at 50 °C and that the half life of the tested substances for hydrolysis is proved to be greater than 1 year. Therefore, it is assumed that the substance defined in section 1 is stable in water as well.
