Description of key information
According to the key ready biodegradability test (OECD Guideline 301F with GLP compliance, 2019), the registered substance attained 74% biodegradation after 28 days of incubation and satisfied the 10 -day window validation criterion. Therefore, the substance is readily biodegradable.
Additional information
To assess the ready biodegradability of the registered substance, one experimental study is available.
This study, from Covance, 2019, assessed as the key study (klimisch 1), was performed on the registered substance according to OECD Guideline 301F and EU Method C.4-D with GLP compliance. The substance, at a concentration of 100 mg/L, was exposed to sewage treatment micro-organisms with mineral medium in sealed culture vessels in diffuse light at temperatures of between 20 and 21°C for 28 days. The biodegradation of the test item was assessed by the measurement of daily oxygen consumption values on days 0 to 28. Control solutions with inoculum and the reference item, aniline, together with a toxicity control were used for validation purposes. The test substance attained 74% biodegradation after 28 days and satisfied the 10 -day window validation criterion, whereby 60% biodegradation must be attained within 10 days of the biodegradation exceeding 10%. The substance can therefore be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No. 301F.
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.
