Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adsorption / desorption
This study estimates the adsorbtion coefficient ot the test item: Greater than 4.27 x 10E5, log10 Koc >5.63, for more than 95% of the test item, using the HPLC screening method, designed to be compatible with C 19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 ofthe OECD Guidelines for Testing of Chemicals, 22 January 2001.
Key values for chemical safety assessment are not at 20 °C, but at 30 °C, because of the HPLC-method and the values are greater than the inscribed estimated values!
The prediction for soil adsorption property of the substance D-glucopyranoside methyl 2,6 -dioleate was determined by the computer program KOCWIN v2.00 (EPIWIN software) by US-EPA (Chemservice S.A., 2017). The program estimates the organic-normalized sorption coefficient for soil, which is designated as Koc. The following two models are used: the Salbjic molecular connectivity (MCI) method as well as the traditional method which is based on the logPow value of the substance. The MCI method is taken more seriously into account, due to the fact that is includes improved correction factors, resulting a Koc value of 4.238E6 L/kg. The traditional method gives a value of 3512 L/kg.
Henry´s Law constant and Distribution modelling
The prediction for the distribution between aqueous solution and air for the substance D-glucopyranoside methyl 2,6 -dioleate was determined by the computer program HENRYWIN v3.20 (EPIWIN software) by US-EPA (Chemservice S.A., 2017). The program calculates the Henry´s Law Constant based on the Bond Method as 4.49 E-008 Pa*m³/mol at a temperature of 25 °C. The Group Method estimation resulted in an Henry´s Law Constant of 1.03E-012 Pa*m³/mol).
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.
