Additional information

The ready biodegradability of the test substance was investigated in two GLP guideline study. rding to EU Method C.4-C (Determination of the "Ready" Biodegradability - Carbon Dioxide Evolution Test) and an enhanced 60 days OECD 310 (CO2 -Headspace Test). In the first study according to EU Method C.4 -C (Determination of the "Ready" Biodegradability - Carbon Dioxid Evolution Test), a biodegradation lower than 10% (based on CO2 evolution) was measured after a test duration of 28 days (Hüls PZ-96/03, 1996). In a second Test according to OECD 310 (CO2 -Headspace Test; BASF SE and LANXESS 2014, 27G0109/13G189) a 60 days incubation reveals 0% biodegradation. Therefore, the test substance is considered to be poorly biodegradable.
