Saturated aliphatic hydrocarbon compound composition, lubricant composition, and method for producing saturated aliphatic hydrocarbon compound composition

A saturated aliphatic hydrocarbon compound composition, comprising:

• a saturated aliphatic hydrocarbon compound, having a carbon number of 40, in 20% by mass or more,
• wherein the saturated aliphatic hydrocarbon compound comprises a plurality of isomers, in a gas chromatography chromatogram of the saturated aliphatic hydrocarbon compound composition, an area of a main peak is 40% or less of a total peak area corresponding to the saturated aliphatic hydrocarbon compound, and the saturated aliphatic hydrocarbon compound composition has an evaporation loss of 4% by mass or less as determined by the Noack method, a kinematic viscosity at 100° C. of 6.5 mm2/s or less, and an average carbon number of 36 to 44.
