Abstract:
1. A base oil, comprising branched hydrocarbons having carbon numbers of at least C 18 , and at least 90% by weight of saturated hydrocarbons, 5-15% by weight of mononaphthenes and further comprising not more than 1% by weight of fused dinaphthenes and polynaphthenes, and wherein at least 75% by weight of the saturated hydrocarbons have a width of the carbon number range of no more than 9, wherein the kinematic viscosity KV100 is from 3 cSt to 8 cSt, and wherein the low temperature dynamic viscosity CCS-30 is no more than 34.066*(KV100) 2.3967 cP, and wherein the 14 C isotope content of the total carbon content in the base oil is at least 50% of the 14 C isotope level in the year 1950, and wherein said base oil is obtained in a process comprising ketonisation, hydrodeoxygenation and isomerization steps, using a feedstock comprising at least one compound selected from the group consisting of triglycerides, carboxylic acids having a carbon number C
