Description of key information
Two reliable measured biodegradation studies in water for the substance are available. Elementis Specialities (2008) conducted a reliable (Klimisch 1) GLP compliant study according to OECD 301 B methods. After 28 days the test substance showed 92.7% degradation, after acidification, based on measured CO2. The substance degraded 81.6% by the end of the 10-day window meeting the criterion. The study concluded that the substance can be considered to be readily biodegradable, passing the 10-day window. In the reliable study by Vendico Chemical (2010) conducted according to OECD 311 methods, the test substance showed 68% degradation, based on CO2 evolution after 28 days.
These studies demonstrate the ready and ultimate biodegradability of the substance and the key study by Elementis Specialities (2008) is taken for the biodegradation in water endpoint.
Additional information
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.
