Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 water solubility of FAT 40850/A TE was determined to be 128.1 g/L at 20.0 °C and a pH of 6.3. The water solubility was not corrected for the purity of the test item.
Key value for chemical safety assessment
- Water solubility:
- 128.1 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of the test item FAT 40850/A TE was tested in a valid GLP study in accordance with the EU method A.6 and OECD guideline No. 105 using the flask shaking method.
The saturation concentration of FAT 40850/A TE at room temperature was estimated by a simplified flask method in the preliminary test to be higher than 0.01 g/L. Therefore, the flask shaking test was performed. The samples were analyzed by HPLC. The measured results differed by less than 15%. Therefore, the study was considered to be valid and the water solubility of FAT 40850/A TE at 20 °C was determined to be 128.1 g/L.
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.
