Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The viscosity for unrefined/acid treated oils ranges from 2.5 to 50 mm2/s at 100ºC and is >2 mm2/s at 40ºC. Viscosity was determined using the EN ISO 3104/ASTM D 445 test methods (CONCAWE, 2010a).


Supporting studies have reported viscosities of >22 mm2/s at 28ºC (Sequeira, 1994) and 11.34 to 51.1 mm²/s at 28ºC (CONCAWE, 1994). Read across data from other lubricant base oils (materials with similar structure and physico-chemical properties) indicates that other lubricant base oils have viscosities ranging from 3.08 to 11 mm²/s at 100°C (CONCAWE, 1997).
