EC number: 265-158-7 | 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.

Description of key information
-60°C to 0°C
Key value for chemical safety assessment
Additional information
To better describe the physical phase or flow characteristics of petroleum substances, the pour point is routinely used. The pour point of other lubricant base oils ranges from -60°C to 0°C. A pour point of 0°C was reported by CONCAWE (2010a). The pour point was determined using the EN ISO 3016 test method. Additionally, various pour point values ranging from -60°C to –6°C have also been reported for other lubricant base oils (CONCAWE, 1997).
