Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on QSAR estimations for the the components, "reaction mass of butane and butene and isobutane" is assessed as readily biodegradable (according to OECD criteria).
Key value for chemical safety assessment
Additional information
Since under environmental conditions the reaction mass consists of different gases distributing preferentially into the air, conducting a standard ready biodegradability test is technically difficult. Therefore, the potential of the reaction mass to biodegrade was estimated by seperate QSAR calculations [BioHCwin v1.01 in EPISuite 4 (2009)] for the components. The results from these QSAR calculations indicate that the components are expected to biodegrade rapidly.
Hence, the reaction mass is assessed as readily biodegradable.
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.
