Description of key information
The biodegradation of the test item was determined in two GLP studies according to OECD 301 F and OECD 301 D.
Key study: Within the test period of 28 days, a degradation of 70 % was determined for the test substance. In addition, at the test concentration of 100 mg/L, no inhibitory effects on the microorganisms from the test substance were observed as estimated in the toxicity control. Given the 10 d window criteria is not fullfilled, the substance is not readily biodegradable according to OECD criteria.
Supporting study: Within the test period of 28 days the degradation of 24% was determined for the test substance. No inhibitory effects on microorganisms at the tested concentration of 2.9. mg/L reference substance and 2.7 mg/L test substance were observed due to a degradation of 49 % in 28 d measured as O2 consumption. According to OECD criteria the substance is not readily biodegradable.
Based on the study results and according to the criteria given in the ECHA Guidance (Guidance on the Application of the CLP Criteria) from 2015, the test substance can be considered for classification as not readily biodegradable.
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.
