mixture

White mineral oil (liquid paraffin)

Highly refined saturated hydrocarbons of lubricant base-oil range, by viscosity grade (e.g. ISO VG 32); composition by grade and refiner. No composition recorded yet: one goes in only with its source (docs/registry.md, Fuel mixtures). di-tert-butyl-dicarbonate-1 lumps it as C28H58 in its own flowsheet (ASSUMED, not a registry value).
