Carnauba wax. Carnauba (/ k ɑːr ˈ n ɔː b ə,-ˈ n aʊ-,-ˈ n uː-,-n ɑː ˈ uː-/; [1] [2] Portuguese: carnaúba [kaʁnaˈubɐ]), also called Brazil wax and palm wax, is a wax of the leaves of the carnauba palm Copernicia prunifera (synonym: Copernicia cerifera), a plant native to and grown only in the northeastern Brazilian states of Ceará, Piauí, Paraíba, Pernambuco, Rio Grande do ...
The fatty acids in wax esters derived from plants typically range from C12-C24, and the alcohols in plant waxes tend to be very long, typically C24-C34. [2] The fatty acids and fatty alcohols of wax esters from different marine animals show major differences. Wax esters of sperm whales contain C12 fatty acids and C14 fatty acid and alcohols.

Cerotic acid, or hexacosanoic acid, is a 26-carbon long-chain saturated fatty acid with the chemical formula CH 3 (CH 2) 24 COOH. [1] It is most commonly found in beeswax and carnauba wax.
A natural wax is chemically defined as an ester with a very long hydrocarbon chain that also includes a long chain alcohol. [2] Examples are: Stearic acid (E570) Beeswax (E901) Candelilla wax (E902) Carnauba wax (E903) Shellac (E904) Microcrystalline wax (E905c), Crystalline wax (E907) Lanolin (E913) Oxidized polyethylene wax (E914) Esters of ...
The materials used to wax produce depend to some extent on regulations in the country of production and/or export. Both natural waxes (carnauba, [12] shellac, beeswax or resin [4]) and petroleum-based waxes (usually proprietary formulae) [3] are used, and often more than one wax is combined to create the desired properties for the fruit or vegetable being treated.
The Carnauba palm tree is an endemic species to the Caatinga, an exclusive Brazilian biome, comprising a total area of 826,411 km².The latter is present in eight of the nine Northeastern states: Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, and it is also present in a northern strip of Minas Gerais.
