Composition
The main components of carnauba are aliphatic esters (40 wt%), diesters of 4-hydroxycinnamic acid (21.0 wt%), ω-hydroxycarboxylic acids (13.0 wt%), and fatty acid alcohols (12 wt%). The compounds are predominantly derived from acids and alcohols in the C26-C30 range. Distinctive for carnauba wax is the high content of diesters as well as methoxycinnamic acid.[3]
Carnauba wax is sold in several grades, labeled T1, T2, and T4, depending on the purity level. Purification is accomplished by filtration, centrifugation, and bleaching.
