Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 265-051-5 | CAS number: 64741-50-0 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 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 aliphatic hydrocarbons normally present in this distillation range of crude oil.

Description of key information
Pour point is the appropriate descriptor of petroleum stream characteristics. The pour point range for unrefined/acid treated oils is -35 to 75°C
Key value for chemical safety assessment
Additional information
Unrefined/acid treated oils have a pour point range of -35 to 75°C (Sequeira, 1994). Although the information of the method used for pour point determination is not known, the information has been provided by the company from secondary sources and is considered reliable with restriction and suitable for use.
Supporting measured pour point data for an unrefined lubricant base oil (CAS No. 64741-50-0) has been reported to be 15.5°C (API, 1987).
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.
