Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 265-052-0 | CAS number: 64741-51-1 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 a relatively large proportion of saturated aliphatic hydrocarbons.

Additional information
The viscosity for unrefined/acid treated oils ranges from 2.5 to 50 mm2/s at 100ºC and is >2 mm2/s at 40ºC. Viscosity was determined using the EN ISO 3104/ASTM D 445 test methods (CONCAWE, 2010a).
Supporting studies have reported viscosities of >22 mm2/s at 28ºC (Sequeira, 1994) and 11.34 to 51.1 mm²/s at 28ºC (CONCAWE, 1994). Read across data from other lubricant base oils (materials with similar structure and physico-chemical properties) indicates that other lubricant base oils have viscosities ranging from 3.08 to 11 mm²/s at 100°C (CONCAWE, 1997).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
