Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phototransformation
No information concerning photodegradation in water or soil is available. A QSAR-Calculation for photodegradation in air with EPI-WIN tool of US-EPA (AOPWin, v1.92) was performed for D-glucopyranoside methyl 2,6 -dioleate. An overall OH rate constant (gas-phase reaction constant) of 203.8268 E-12 cm3/molecule-sec [Cis-isomer] and 219.0268 E-12 cm3/molecule-sec for cis and trans isomer were calculated, respectively. A half-life of 1.889 and 1.758 hours for 12 -h day and 24 -h day were calculated, respectively. No ozone reaction as well as no nitrate radical reaction is estimated for the desired chemical (note: "Reaction with Nitrate Radicals May Be Important"). Since these are no mandatory endpoints under REACH, thus no experimental investigation is intended. Based on the produced and supplied form of the test substance, no phototransformation in the environmental compartment is expected.
Hydrolysis
Testing according to Method 111 of the OECD Guidelines for Testing of Chemicals couldn't be performed for the following reasons:
• The test item as a whole was expected to be essentially insoluble in water. Therefore, the test solution concentration required, which would need to be less than half the water solubility, that would dissolve all the components would be impractically low in order to perform the test. Also, a sufficiently sensitive analytical method was not available. Overall, these issues would make hydrolysis testing unfeasible.
• The test item is a complex mixture which the test method is not ideally suited to because each component that is unstable is likely to have its own hydrolytic rate. Also, if hydrolysis occurred many components would by hydrolyzed into the same structure as other components already present within the test item. It would then not be possible to distinguish between the original components and the hydrolysis product. The main functional groups within the components of the test item were ethers and esters. Ethers do not usually hydrolyze within environmentally relevant pH and temperature. Although esters can hydrolyze, especially in alkaline conditions, the test item components are considered to have a significantly reduced hydrolytic rate due to them being essentially insoluble in water. This is especially the case with the larger products that would be highly hydrophobic. The smaller products may be more susceptible to hydrolysis as they would have the potential to emulsify in water.
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.
