Applicant's summary and conclusion
- Conclusions:
- The representative component of the registered UVCB is predicted to partition mainly to soil (approximately 74.3 %).
- Executive summary:
Since the registered UVCB substance has been shown to be readily biodegradable, distribution of a representative constituent was predicted using a Level III Fugacity Model. The constituent is predicted to partition mainly to soil (approximately 74.3 %).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
