Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The substance is stable in water.
Key value for chemical safety assessment
Additional information
Two studies on the hydrolysis of the substances in the stilbene fluorescent whitening agents are available. Both studies (for CAS 16090-02-1 and CAS 16470-24-9) 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 (CIBA-GEIGY 1992). Therefore, reading across, it is assumed that the subtsance CAS 371756 -75 -1 is stable in water as well.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
