There are a number of different classes of naphtha and similar naphtha types may be called by different names. Light naphtha will normally have a higher content of straight chain paraffins and is sometimes referred to as paraffinic naphtha or straight run gasoline. Heavy naphtha usually contains more naphthalenes and aromatics and may be called N&A naphtha. Light naphtha can also be used in industrial solvents and cleaning fluids. Applications include varnishes and paints, shoe polish, lighter fluid and fuel for portable stoves and lanterns.
