Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

0.81 to 0.97 g/cm3 at 15°C 

Key value for chemical safety assessment

Additional information

Density determinations for a number of refined other lubricant base oils ranged from 0.81 to 0.97 g/cm3 at 15°C using EN ISO 21285/ASTM D4052 (CONCAWE, 2010a). An additional range of 0.857 to 0.950 g/cm3 was obtained following ASTM D4052 (CONCAWE, 1997). As a result, these substances are expected to float if released to water.

The studies below were conducted using International Organization for Standardization (ISO) method ISO 12185

Density values (g/cm3) for Other Lubricant Base Oils (CONCAWE, 1997)

Solvent-dewaxed, light paraffinic (64742-56-9): 0.85 g/cm3

Solvent-dewaxed, heavy paraffinic (64742-65-0): 0.86 g/cm3

Hydrotreated, light paraffinic (64742-55-8): 0.86 g/cm3

Hydrotreated, heavy paraffinic (64742-54-7): 0.88 g/cm3

Hydrotreated, light naphthenic (64742-53-6): 0.87 g/cm3

Hydrotreated, heavy naphthenic (64742-52-5): 0.91g/cm3
