Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

kinematic viscosity of the test material:
- 3.42 mm2/s at 40°C and 5.50 mm2/s at 20°C
- 2.3 - 2.7 mm2/s at 40°C [supporting information; product properties data by company (result of 13 determinations/batches; study period: 06/2011 - 01/2012)]

Key value for chemical safety assessment

Additional information

The viscosity was determined using OECD Test Guideline 114 (Viscosity of Liquids):

The viscosity of the test material ‘Distillates (Fischer-Tropsch), C8-26 - branched and linear' has been determined to be 3.42 mm2/s at 40°C and 5.50 mm2/s at 20°C.

However, the substance is a mixture of hydrocarbons (UVCB substance) and has varying viscosities:

the reported viscosity of 2.3 - 2.7 mm2/s describe the range of 13 different batches [product properties data by company (study period: 06/2011 - 01/2012)].

In general terms, lower viscosity grade products contain relatively higher proportions of lower carbon number consistuents.
