Percentage of wax content
Carnauba wax is considered to be the world’s purest, hardest and most transparent natural wax repellent derived from the Brazilian palm Copernia Cerefera
A Carnauba wax needs to have clarity to enable the base coat colour to be seen. Most wax products use an unrefined yellow wax (plus emulsifiers, fillers (Diatomaceous earth) and solvents) As far as percentage of wax the lower percentage will ensure surface clarity and as the yellow Carnauba percentage increases surface clarity will depreciate. Most yellow wax products contain 15-20% Carnauba wax by weight
Since Carnauba wax exhibits the qualities that Concours d’élégance vehicle preparation detailers and judges look; Colour, Depth and Clarity, when scrutinizing paint film surfaces. So much depends on proper surface preparation, a clean and level surface, and product clarity, which allow the natural properties of the paint to show through, as without transparency the true colours of the paint surface cannot be seen.
Carnauba wax gives a rich, deep, wet looking shine, as well as a higher content % to give off more added surface protection for the solution to a higher wax content is to ensure clarity with a refined ivory Carnauba (the so-called ‘# 1 white’) which varies from a very pale yellow (so called ‘white’), through a greenish brown (yellow) higher quality emulsifier and solvent are also needed, with less fillers as these will lessen clarity.
Misinformation propagates the myth that increasing the Carnauba content of a wax will greatly improve the wax. 100% carnauba really means that all of the wax used in the product is Carnauba (i.e. no Beeswax or other waxes are used) It's worth pointing out that this part of the formula could be as little as maybe 3% of the overall product
This is only very marginally true at best; most carnaubas advertised with 50% or more Carnauba wax content is truly advertising a weight, not a total finished product (volume) 30% by volume is about 50% by weight is about t estimated carnauba saturation point 25-35% natural Carnauba (approx 35% Carnauba by volume makes it almost impossible to add/remove) that’s why you never can truly assess the amount of Carnauba in a manufactured wax unless the manufacturer specifically lists its content stated by percentage weight or volume.
When making a comparison ensure you compare like with like (i.e. % volume or % weight) as some Carnauba percentages refer to % of Carnauba as a proportion of wax content only ( i.e. 70% carnauba, 30% beeswax). Wax in itself will not produce a gloss or shine; wax is a dull substance that provides protection, and will not produce gloss without the addition of an additive (oils, silicones, etc) which will produce a reflective gloss, jetting (the so called ‘wet-look) or depth.
Carnauba weighs twice as much as solvent. For example, a 50% or more carnauba content by volume is actually slightly more than 30% by weight. Most carnaubas advertised with 50% or "more" in carnauba content are truly advertising a weight, not a volume.
Only a small portion of your vehicle's shine comes from the wax itself. Carnauba is translucent at best with only minimal light reflection. Maximum shine comes from a clean, prepared and level surface; it improves the desired optical properties i.e. surface reflectance
