Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
In conclusion, the log of the adsorption coefficient (Koc) of ucb 22060 was estimated to be log KOC = -0.3 which is equal to a Kocvalue of 0.5 using the HPLC method. This value indicates that ucb 22060 will not be absorbed by organic carbon in soil and that ucb 22060 is very high mobile.
