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.
