Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The test substance is a solid, water soluble, with very low vapour pressure and a negative Kow.
It resulted hydrolytically stable: it is stable at pH 4, 7 and 9 at 50 °C and it has a half-life period longer than one year at 25 °C at pH 4, 7 and 9. The substance has not hydrolysable chemical groups in the chemical structure.
Based on calculations according to AOPWIN v1.92, the substance is indirectly photodegraded by reaction with hydroxyl radicals in the atmosphere with half-lives of about 18/19 minutes taking into account a 12-h day and a mean OH radical concentration of 1.5E06 radicals per cm³. The substance undergoes photodegradation in surface water, with half lives that range from about to 4 to 5 hours, but this process is effective mainly in the photic zone of lakes and rivers and near the surface.
Adsorption will partially bring the substance onto the surface of suspended particles and will also contribute to the adsorption of the substance into sediments, where an anaerobic degradation process can be effective. Nevertheless this is unlikely to occur in the usual conditions of use, where the substance is adsorbed to the sludge in the STP, therefore significant release into surface waters is not expected and exposure of sediment is thereby unlikely.
The substance has been demonstrated as not bioaccumulative.
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.
