Additional information

For the assessment of biodegradability a non-GLP test according to OECd guideline 301E was identified. As inoculum, non-adapted domestic activated sludge from a laboratory scale STP was used. After 8 days the test substance was degraded at an amount of 80 -90% related to the DOC elimination (BASF 1990).
