EC number: 265-159-2 | CAS number: 64742-56-9 A complex combination of hydrocarbons obtained by removal of normal paraffins from a petroleum fraction by solvent crystallization. It consists predominantly 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).

Description of key information
Viscosity @ 40° C > 2 mm2/s (CONCAWE, 2010a; CONCAWE, 1984; CONCAWE, 1997)
Viscosity Values for Other Lubricant Base Oils (mm2/s), at 40°C and 100°C (CONCAWE, 1997):
Solvent-dewaxed, light paraffinic (64742-56-9): 8.4, 2.4
Solvent-dewaxed, heavy paraffinic (64742-65-0): 25.1, 4.8
Hydrotreated, light paraffinic (64742-55-8): 17.0, 3.7
Hydrotreated, heavy paraffinic (64742-54-7): 73.9, 9.1
Hydrotreated, light naphthenic (64742-53-6): 8.5, 2.2
Hydrotreated, heavy naphthenic (64742-52-5): 145, 10.5
Key value for chemical safety assessment
Additional information
Other lubricant base oil viscosity is considered to be > 2 mm2/s at 40°C. A viscosity range of 1.99 to 847 mm2/s at 40°C was reported by CONCAWE (2010a). The viscosity was determined using the EN ISO 3104/ ASTM D 445 test method.
Other lubricant base oil viscosities may also be characterised by measured values for several lubricant base oil samples, which range from 4.48 to 1300 mm²/s at 40°C, (viscosity values for the same samples at 100°C were 3.08 to 50 mm²/s), according to Method ASTM D 445 (CONCAWE, 1984; 1997). These studies received Klimisch scores of 2 and are classified as reliable with restrictions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
