Additional information
In a non-GLP study conducted according to OECD Guideline 301E, the biodegradability of the substance (CAS 149-57-5) was studied (Finnish Chemicals Oy, 1998, report no. E2807). The inoculum was primary effluent from a wastewater treatment plant treating predominantely municipal wastewater. The degradation reached 99% (DOC removal) after 28 days of exposure. The limit for ready biodegradability (>60%) was reached within the 10 days window. The test met the validity criteria of the guideline.
The substance is readily biodegradable according to OECD criteria.
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.
