Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
The chromatograms resulting from Fatty Acids, C16-18 and C18 Unsaturated, Branched and Linear samples extracted from water show a different profile of peaks to those derived from the method standards (dissolved in solvent). The additional peaks found in the water extracts are likely to be components of significantly greater solubility than, or degradents from, the component used in the method quantification. These more soluble components are present at low to trace levels in Fatty Acids, C16-18 and C18 Unsaturated, Branched and Linear.
The water solubility of Fatty Acids, C16-18 and C-18, Unsaturated, Branched and Linear, measured as the sum solubility of all the components of the test material was estimated to be 15.0 mg/L at 20°C. However, the water solubility based on its two major constituents is 0.6 mg/L at 20°C.
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.
