Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No experimental studies investigating the adsorption/desorption potential of the UVCB substance D-Glucopyranose, oligomeric, undecyl glycoside (CAS 98283-67-1) are available. Therefore, the adsorption/desorption indicator log Koc was calculated using KOCWIN v2.00 (EPI Suite) based on the Molecular Connectivity Index (MCI) as well as the log Kow. The QSAR calculations were conducted for the three main constituents. The log Koc values ranged between 2.01 and 3.95 (based on MCI). The log Koc values based on log Kow were calculated to be between -1.87 and 1.25. These values indicate a partial adsorption potential for at least one of the three constituents of the UVCB substance. However, QSAR results have to be regarded with caution as two of the three main constituents do not completely fit in the applicability domain of the model due to their low log Kow values (-2.58 and -0.09).
However, the substance is expected to be extensively eliminated in sewage treatment plants, due to ready biodegradability. In case of a release in the environment, it is expected to be rapidly degraded by microorganisms in both aquatic and terrestrial compartments.
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.
