Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

QSAR (WSKOWWIN v1.42):
13.19 mg/L at 25 °C (C12 monoester component)
0.00001281 mg/L at 25 °C (C12 diester component)
0.01218 mg/L at 25 °C (C18 monoester component)
Key value for chemical safety assessment
Additional information
The water solubility of the substance was experimentally determined with column elution method according to EU Method A.6. The determination was done via sorbitan monolaurate as representative of the main compound in the test item. Further compounds are carbon hydrates (well water soluble) and sorbitan di- and trilaurate.
The result reflects the limit of determination (LOD) of the analytical method (sample preparation and analysis with GC-MSD) of 3.3 mg/L.
In addition QSAR calculations were performed with WSKOWWIN for the main components of the substance (C12 monoester, C12 diester and C18 monoester). Results for the C12 monoester component show a high water solubility (13.19 mg/L at 25 °C), for the C18 monoester and the C12 diester components the water solubility decreases significantly (0.012 mg/L and 0.00001 mg/L respectively). The QSAR results support the statement of the experimental study that C12 monoester is the most soluble ester component of the substance. Other compounds like carbohydrates are well soluble whereas the di- and triester compounds are less soluble.
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.
