Description of key information

Not readily biodegradable (according to OECD criteria)

Key value for chemical safety assessment

Additional information

To assess the biodegradation potential of DAP-MCDA, a GLP-guideline study according to OECD 301B was performed (BASF SE, 2019, report no.: 22G0592/17G604). As inoculum activated sludge from the municipal wastewater treatment plant of Mannheim, Germany, was used. The test duration was prolonged to 60 days. All validity criteria were fulfilled.

After 60 days, a degradation of 19% CO2/ThCO2 was observed (the duration of the adaptation phase was around 55 days). Hence, the substance cannot be considered readily biodegradable (according to OECD criteria).
