Description of key information
The surface tension range of Hydrocarbons, C7-C9, n-alkanes, isoalkanes, cyclics is 20 to 24 mN/m at 25°C.
Key value for chemical safety assessment
Additional information
Wilhelmy plate method is used to measure the surface tension using a standardized plate with a plate tensiometer. A range of 20 to 24 mN/m covers all possible grades within this substance description if measured with the agreed method. Using this method Total Fluides (2010) determined the surface tension to be 18.3 -20.0 mN/m at 25 °C, demonstrating that the measured value falls within borderline values.
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.
