CAS number: 64742-55-8
A complex combination of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst. It consists of hydrocarbons having carbon numbers predominantly in the range of C15 through C30 and produces a finished oil with a viscosity of less than 100 SUS at 100°F (19cSt at 40°C). It contains a relatively large proportion of saturated hydrocarbons.
0.81 to 0.97 g/cm3 at 15°C
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
