Like I said, I could be wrong!
I am still of the opinion that all waxes contain petroleum distillates. This issue has been discussed in various auto detailing forums. I will repeat from my prior post:
Carnauba is rock hard in its natural form. When the leaves of the Tree of Life are harvested, the wax flakes off as the leaves dry out, or they are put into a machine that removes the wax. It comes off in hard flakes. Car Wax makers have to blend the wax with oils, petroleum distillates, or a solvent called naptha (commonly used to thin wood varnishes and paints) in order to make the wax workable.
So oils, petroleum distillates, or a solvent called naptha have to be used in order to make the wax workable. Naptha = petroleum distillate. Oil = petroleum distillate (unless they are using some kind of plant based oil which I doubt).
Again, please let me know what wax manufacturer is specifically claiming that they "do not use any petroleum distillates" in their wax.
