EC number: 265-054-1 | CAS number: 64741-53-3 A complex combination of hydrocarbons produced by vacuum distillation of the residuum from atmospheric distillation of crude oil. It consists of hydrocarbons having carbon numbers predominantly in the range of C20 through C50 and produces a finished oil with a viscosity of at least 100 SUS at 100°F (19cSt at 40°C). It contains relatively few normal paraffins.

Additional information
The boiling point range for unrefined/acid treated oils is 210 to 800°C (CONCAWE, 2010a; CONCAWE 1997). The boiling point was determined using the EN 15199 test method.
Supporting read-across data from other lubricant base oils (materials similar in structure and physico-chemical properties to unrefined/acid-treated oils) has also been reported. Other lubricant base oils have boiling points ranging from about 300 to 800°C (CONCAWE, 1997).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
