Distillates (petroleum), hydrotreated light naphthenic (10C)
Distillates, petroleum, hydrotreated light naphthenic
A complex combination of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst.  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.degree.F (19cSt at 40.degree.C).  It contains relatively few normal paraffins.
