So, what I said is true for natural carnauba wax only - and if a product contains other stuff, that for ex. uses polymer technology (which works completely different, than simple solvent-based compounds), then obviously what I said does not or at least might not apply to that particular product.
Also, the fact that a product contains some carnauba, does not mean that it's actually carnauba that's working its magic in there, or that it has any measurable effect on the outcome of how the product works; or that a significant amount of carnauba is left back cured on the surface after its been wiped off. See again marketing! Ie. some manufacturers might add some - possibly negligible - amount of carnauba to their products just for the very sake of being able to say that there's "carnauba" in it, or that it's in some way "natural", solely because of the positive feelings associated with these words, without these ingredients actually doing anything in the product or being determining in how these products achieve their results.
