Description of key information
- kinematic viscosity of substance 'Paraffin waxes (Fischer-Tropsch), isomerization' at 100ºC (determined using Method ASTM D445): 18.86 mm2/s at 100°C
- estimated range (depending on the product grade): 18-21 mm2/s at 100°C
Key value for chemical safety assessment
Additional information
The registration substance is a mixture of hydrocarbons (UVCB substance) with a range of viscosities; the reported viscosity of 18.86 mm2/s at 100°C derives from one grade that is relevant for supply in the EU.
In general terms, higher viscosity grade products contain relatively higher proportions of higher carbon number constituents.
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.
