Applicant's summary and conclusion
- Validity criteria fulfilled:
- no
- Interpretation of results:
- other: inherently and ultimately biodegradable
- Conclusions:
- Akigalawood did not inhibit the intrinsic respiration of the inoculum at the test concentration and was therefore considered to be non-toxic to the inoculum at the test concentration.
Thus, Akigalawood should be regarded as not readily biodegradable according to this test. However, based on these results Akigalawood should be regarded as inherently and ultimately biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
