Description of key information

The mixture is not readily biodegradable (accoring to OECD criteria)

Key value for chemical safety assessment

Additional information

Since no biodegradation test data for the multi-constituent substance are available, the assessment of the biodegradation potential based on test results of the two components.

In a GLP study performed with the minor component (CAS 6674-22-2) an degradation rate of 2% after 31 days was measured. The test procedures followed OECD guideline 301 E [BASF 1988].

In a GLP test performed with the major component (CAS 24566-95-8) an degradation rate of 21% after 28 days were determined. The procedures of this test followed OECD guideline 301 A.
