Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Applicant's summary and conclusion

Interpretation of results:
not readily biodegradable
Conclusions:
VSV16 is not ready biodegradable according to the OECD criteria.
Executive summary:

The degradation extent of the test item at the end of the test was -12.7% (mean of three replicates).

The criterion for ready biodegradation was not met (degradation ≥ 60% and fulfilment of 10-d-window) therefore the test item is not ready biodegradable according to the OECD criteria.
