Carnauba is the hardest natural occurring wax available. Carnauba is primarily harvested from palm trees in Brazil. The wax is melted down and added to Meguiar's formulations to enhance their durability and protection against the environment as well as adding gloss to your car's finish. Meguiar's uses only #1 yellow Carnauba wax, the most costly and highest quality grade.

There are other companies touting the fact that they use an even higher grade of Carnauba wax called Ivory Carnauba wax. Ivory Carnauba wax is simply #1 yellow Carnauba wax that has been decolorized to remove the natural yellow color. The decolorizing process in no way, shape or form increases the quality of the Carnauba wax. If anything, the decolorizing process could diminish the quality of the Carnauba because the chemicals used are rather harsh. Decolorizing Carnauba is an unnecessary step that would appear to be more of a marketing ploy to create a perception of "added value" - when in reality it is much to do about nothing - to put a few more dollars in the hands of the seller
