Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- inherently biodegradable
- Conclusions:
- Toscanol undergoes 55% biodegradation after 28 days (73% biodegradation after 57 days) in the test conditions.
Thus, Toscanol should be regarded as inherently biodegradable according this test method.
