Description of key information

An OECD TG 301D (Closed Bottle Test) guideline study in compliance with GLP is available for the test substance. In this study, 2 mg/L of the test substance was exposed for 28 days to secondary activated sludge from a wastewater plant treating predominantly domestic wastewater. Endogenous respiration or microorganisms degrading acetate were not affected throughout the test. After the 28-day exposure period 63% of the test substance was biodegraded. The pass level of 60% was reached after 10 to 11 days upon achieving 10% biodegradation. Therefore, the test substance fulfilled the 14-day time window. Based on the findings, the test substance is classified as readily biodegradable.
