Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

ultimate anaerobic biodegradability (ISO 11734): 106% degradation after 56 days
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Two studies investigating the biodegradation of D-Glucopyranose, oligomeric, butyl glycoside are available. In the key study, the ready biodegradability of the substance was tested according to OECD 301F and GLP (IBACON, 2008). Domestic activated sludge was used as inoculum. As a result, 114% of the test substance was degraded after 28 days (ThOD NH4) and the 10-day window in which the test substance must be degraded by ≥ 60% was met. In conclusion, D-Glucopyranose, oligomeric, butyl glycoside can be considered as readily biodegradable based on OECD criteria.
Another study investigated the ultimate biodegradability of D-Glucopyranose, oligomeric, butyl glycoside under anaerobic conditions in digested sludge by measurement of biogas production according to ISO 11734 (Safepharm, 2003). Domestic sewage was used as inoculum. The test substance was completely degraded after 56 days.
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.
