Description of key information

The test substance was biodegraded by 38 % over 28 days. The test substance is classified as not readily but inherently biodegradable according to the OECD criteria.

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable

Additional information

The ready biodegradability of the test substance was investigated according to the OECD guideline 301D: Closed bottle test (1992). The biodegradation of the test substance was followed by exposing it in a mineral medium and incubated for 28 days under aerobic conditions. At the end of the test, after 28 days the test substance was biodegraded by 38 %, therefore the test substance is classified as not readily but inherently biodegradable. The validity criteria were met.
