Description of key information

According to the result of the key study Methoxyacetic acid is readily biodegradable in this OECD 301A/EU C.4-A test. Degradation of the test substance was 98 % after 10 days if a test concentration of 48 mg/L (equivalent to 20 mg/L DOC) is used.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

In a DOC Die-Away test Methoxyacetic acid was tested using a concentration of 48 mg/L (corresponding to a 20 mg/L DOC) in test medium following OECD 301A and EU-Guideline C.4 -A. Effluent from a sewage treatmnat plant was used as inoculum (conc. 30 mL effluent/L). Anniline was used as positive control. Degradation after 10 days was 94 %. The

test was terminated after 10 days as biodegradation for the test substance was 98 %. Therefore Methoxyacetic-acid is readily biodegradable following OECD 301A.
