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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Abiotic degradation:
The constituents of the substance do not have functional groups subject to hydrolysis. Therefore, hydolysis is not excpected.
Biodegradation:
The constituents of the UVCB substance are adsorptive and poorly water soluble. The UVCB substance is poorly biodegradable in a ready biodegradability test. Comparable degradation rates are expected for biodegradation in surface water, sediment and soil.
Bioaccumulation:
In a weight-of-evidence approach balancing different QSAR estimations and experimental data of representative constituents and a substance similar to a constituent, significant accumulation of the certain constituents of the UVCB substance in organisms are expected. It is concluded that the BCF is < 2000. As worst case the experimental value of 1730 L/kg is used for the CSA.
Transport and distribution:
The adsorption/desorption partition coefficient of >3 indicates immobility in soil and adsorption to suspended particles for the components of the UVCB substance. Thus, the UVCB substance will mainly distribute to soil and sediment.
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.
