Description of key information
Sodium perborate is rapidly degraded in river water.
Key value for chemical safety assessment
- Half-life in freshwater:
- 2.5 d
- at the temperature of:
- 296 K
Additional information
The degradation of sodium perborate monohydrate in river water was determined by measuring the decrease of active oxygen. After an incubation period of 28 days 85% of the initial sodium perborate concentration (15 mg/L) had been removed (Degussa 1994). From the data measured by Degussa a half life time of about 59 hours for the degradation of sodium perborate monohydrate in river water was estimated.
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.
