EC number: 295-301-9 | CAS number: 91995-40-3 A complex combination of hydrocarbons obtained from an intensive treatment of dewaxed distillate by hydrogenation in the presence of a catalyst. It consists predominantly of saturated hydrocarbons having carbon numbers predominantly in the range of C21 through C29 and produces a finished oil with a viscosity of approximately 13cSt at 50°C.

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
