Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The n-octanol/water partition coefficients of the components of Isostearic acid, esters with methyl α-D-glucoside were determined as follows:
log Pow at 25 °C and pH 7: < 0.3 for most likely methyl glucoside (ca. 4 %)
log Pow at 25 °C and pH 7: > 6.5 for all other components (ca. 80% methyl glucoside isostearate esters, ca. 16% isostearic acid)
Key value for chemical safety assessment
- at the temperature of:
- 20 °C
Additional information
The n-octanol/water partition coefficient of the components of Isostearic acid, esters with methyl α-D-glucoside was determined according to OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method, 2004) and EU Method A.8 (Partition Coefficient, 2008). Since it was not possible to elute the test substance under isocratic conditions with a mobile phase of 75/25 (v/v) methanol/water, a gradient was applied directly after the isocratic run in order to rinse the test substance off the column.
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.
