Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two experimental results for the biodegradation of the Reaction product of D-Glucopyranoside, methyl; esterified with oleic acid, methyl ester (generic name: D-glucopyranoside methyl 2,6 -dioleate) are available.
Referring to the key study (Best, 2015) the biodegradation of the test item was assessed by the determination of carbon dioxide produced. Control solutions with inoculum and the reference item, sodium benzoate, together with a toxicity control were used for validation purposes.
The test item attained 94% biodegradation after 28 days and satisfied the 10-Day window validation criterion, whereby 60% biodegradation must be attained within 10 days of the biodegradation exceeding 10%. The test item can therefore be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No. 301B.
According to the supporting study (Clarke, 2004) the test material attained 94% degradation afier 28 days. Under the strict terms and conditions of OECD Guideline No 301B the test material cannot be considered to be readily biodegradable as the test material failed to satisfy the 10-Day window validation criterion, whereby 60% degradation must be attained within 10 days of the degradation rate exceeding 10%. However, the test material has exhibited the potential for rapid degradation. In terms of the classification and labelling requirements (EU Directive for Dangerous Substances, L 110A) the test material may be considered as readily biodegradable as evidence of >70% degradation has been shown over a 28-Day period in a standard biodegradation study.
Based on the results of these studies, D-glucopyranoside methyl 2,6 -dioleate is expected to be 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.
