Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

No experimental studies investigating the bioaccumulation potential of D-Glucopyranose, oligomeric, undecyl glycoside (CAS 98283-67-1) are available. According to column 2 of Annex IX REACH Regulation 1907/2006, studies on the accumulation in aquatic species do not need be conducted as the substance has a log Kow of ≤ 3 and therefore a low potential for bioaccumulation is expected.

This assumption is supported by the BCF (bioconcentration factor) values calculated for the main constituents of the substance with the reliable QSAR model (BCFBAF v3.01, EPI Suite). BCF values of 0.8931 to 10.18 L/kg were estimated using the Arnot-Gobas method, including biotransformation (BCFBAF v3.01, EPI Suite). The BCF values are well below 2000, indicating a low potential for bioaccumulation.

Furthermore, the substance can be digested by common metabolic pathways, which enhances the assumption of no bioaccumulation in organisms. For a detailed review on metabolism of the substance, please refer to the toxicokinetics statement in IUCLID section 7.1.
