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 ...
Triacontanyl palmitate, a typical wax ester, is derived from triacontanyl alcohol and palmitic acid. A wax ester (WE) is an ester of a fatty acid and a fatty alcohol. Wax esters are the main components of three commercially important waxes: carnauba wax, candelilla wax, and beeswax. [1]
From the commercial perspective, the most important plant wax is carnauba wax, a hard wax obtained from the Brazilian palm Copernicia prunifera. Containing the ester myricyl cerotate, it has many applications, such as confectionery and other food coatings, car and furniture polish, floss coating, and surfboard wax.
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. It is a white solid, although impure samples appear yellowish.
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 ...
Typical microcrystalline wax crystal structure is small and thin, making them more flexible than paraffin wax. It is commonly used in cosmetic formulations. [2] Microcrystalline waxes when produced by wax refiners are typically produced to meet a number of ASTM specifications. These include congeal point (ASTM D938), needle penetration (ASTM ...
Chemical formula. C 34 H 68 O 2: Molar mass: ... It occurs in cotton, carnauba, candelilla wax, and in ghedda wax (wild beeswax), from which its common name is derived.
Wax emulsions based on beeswax, carnauba wax and paraffin wax are used in creams and ointments. The emergence of soybean waxes with varying properties and melt points has led to the use of vegetable wax emulsions in applications such as paper coatings, paint and ink additives, and even wet sizing for pulp and paper applications.
