Jason is absolutely correct. In fact, ALL carnauba formulations are full of oils and/or silicones. This is the only way for them to shine. Carnauba wax is really a yellow dull wax with little durablilty, and it attracts dust/dirt like a magnet. BUT, it's the oils and silicones in the Souveran or any wax that give the appearance of "depth." Even some polymer formulations that claim to add depth are full of silicone oils. And, that's what many prefer, the warmer, deeper look, which is fine if that's what you're after. P21S, Zymol, you name it, they're ALL full of different blends of oils and silicones. Zymol is one of the worst IMHO. This is some of the ingredients of one of their upper end waxes: Contains White Carnauba Sap/Wax, Montan Evergreen Oil, Sunflower Oil, Cantaloupe Oil, Coconut Oil, Honeydew Extract, Propolis (derived from Bees), Cetyl Esters, Cetyl Cocoamide (derived from coconut oil). Does a car need all these oils? You be the judge?
