Q: Why is carnauba wax mixed with other ingredients?
A: Carnauba wax is as hard as concrete in its pure form, and could never be applied without having been softened or dissolved (to form a paste or solution) first. That's why all those '100% Carnauba' claims have to be taken with a pinch of dodo poo. It's also important to realise that carnauba is just one part of a good car wax. The quantity and quality of other ingredients, like beeswax, lubricating oils and drying oils, are also critical.
Q: OK, so how much carnauba is actually in Dodo Juice?
A: It depends on the individual wax, but Dodo Juice waxes generally have between 25%-35% carnauba content when measured without any jiggery-pokery. In our experience, the highest concentration of carnauba in a car wax that can be applied straight from a tin at room temperature is around 40%. If a manufacturer is claiming a lot more, then it is likely they are simply *calculating* a lot more. You can get Carol Vorderman to take the true percentage, divide by the number of days in the year and then multiply by the square root of your hamster's age to come up with a pleasing figure. Or you can measure carnauba by dry volume (instead of the more usual wet volume), by solids content, by overall wax content or by residual content. Basically any way you want. But it doesn't necessarily mean the wax is better. There's only one way of finding that out, and that's by slapping it on some paintwork. Needless to say, we don't state carnauba percentages on our products because they are too confusing and generally mislead the public. We'll take our chances without relying on any dubious marketing techniques. You can see an experiment we did with carnauba measurement here.
