Patent number: 8053614Abstract: The invention relates to a new base stock material. Specifically the invention relates to a saturated hydrocarbon composition and particularly to a composition based on biological raw materials, to be used as a high-quality base oil or to be used as a component in the production of a base oil having a high viscosity index and good low temperature properties. The composition contains saturated hydrocarbons and has a narrow carbon number range.Type: GrantFiled: December 12, 2006Date of Patent: November 8, 2011Assignee: Neste Oil OYJInventors: Pekka Aalto, Juha Moilanen, Janne Jokinen, Eija Koivusalmi, Jukka Myllyoja, Juha Jakkula, Vesa Niemi
