You're quite confused. Go to Walmart or paint store and read some labels.
Or have a read in the Kirk-Othmer at the library.

White gas, white spirit, naphtha, Coleman fuel, Zippo fuel, Ronsonol, are

Charcoal starter is a heavier weight, roughly kerosene. Using naphtha for
such a purpose would be stupidly hazardous. Especially for those who have
a habit of squirting it on a slow fire.
