Additional information
An experimentally derived value is available for Octadecane, using ASTM method D4052 (Shell, 2014). Further two values obtained are from literature sources with no specific details of methodology.
The available information is consistent and provides sufficient data to allow a reliable result to be determined.
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.
