Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Water solubility of FC-43 was < 0.0561 ug/L at approximately 23˚C (OPPTS 830.7840).
Water solubility of FC-40 was < 0.0508 ug/L at approximately 23˚C (OPPTS 830.7840).
Key value for chemical safety assessment
Additional information
The water solubilities of FC-43 and FC-40 were measured according to OPPTS 830.7840 “Water Solubility: Column Elution Method; Shake Flask Method” and were conducted under GLP. Triplicate FC-43 samples were incubated for 1, 2, 3, and 4 days at approximately 30 °C, while triplicate FC-40 samples were incubated for 1, 2, and 5 days at approximately 30 °C. Each sample was analyzed in duplicate using a purge and trap gas chromatography/mass spectrometry (GC/MS). The measured water solubilities for FC-43 were less than the Lower Limit of Quantitation (LLOQ) of 0.0561 ug/L at approximately 23˚C. The measured water solubilities for FC-40 were less than the Lower Limit of Quantitation (LLOQ) of 0.0508 ug/L at approximately 23˚C.
A previous study conducted in 1984 using Total Organic Carbon method reported the water solubility of FC-43 of <2 mg/L at temperature between 23 and 24 °C. It is not known if the sample had reached saturation and equilibration. However, this study supported the low water solubility of FC-43.
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.
