Description of key information

One reliable key study is available on the registered mixture. The test item attained 45% degradation after 28 days and therefore cannot be considered to be readily biodegradable under the strict terms and conditions of the test.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

A study was performed to assess the ready biodegradability of the registered mixture in an aerobic aqueous medium. The method was designed to be compatible with the OECD Guidelines for Testing of Chemicals (1992) No 301B, "Ready Biodegradability; Closed Bottle: CO2 evolution test , Method C.4-E of Commission Regulation (EC) No. 440/2008, and US EPA Fate, Transport, and Transformation Test Guidelines OPPTS 835.3110 Paragraph (m).

 

The test item attained 45% degradation after 28 days and therefore cannot be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No 301D.
