Description of key information

According to a screening test, the biodegradation in water of the test item was 53% after 28 days.

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable, fulfilling specific criteria

Additional information

In a CO2 evolution test conducted according to OECD 301B guideline, the test item was exposed to non-adapted micro-organisms from activated domestic sewage sludge. A biodegradation (ThCO2) of the test item of 53% after 28 days was found. Under the test conditions, the test substance was not readily biodegradable but showed potential for inherent biodegradability.
