Carnauba wax

Carnauba (kɑːrˈnɔːbə,-ˈnaʊ-,-ˈnuː-,_-nɑːˈuː-; 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, Pernambuco, Rio Grande do Norte, Maranhão and Bahia. It is known as the "Queen of Waxes". In its pure state, it is usually available in the form of hard yellow-brown flakes. It is obtained by collecting and drying the leaves, beating them to loosen the wax, then refining and bleaching it. As a food additive, its E number is E903. Carnauba consists mostly of aliphatic esters (40 wt%), diesters of 4-hydroxycinnamic acid (21.0 wt%), ω-hydroxycarboxylic acids (13.0 wt%), and fatty alcohols (12 wt%). The compounds are predominantly derived from acids and alcohols in the C26-C30 range. It is distinctive for its high content of diesters and its methoxycinnamic acid. It is sold in grades of T1, T3 and T4 according to its purity level, which is accomplished by filtration, centrifugation and bleaching. Because it creates a glossy finish, carnauba wax is used in automobile waxes, shoe polishes, dental floss, food products (such as sweets), polishes for musical instruments, and floor and furniture waxes and polishes, especially when mixed with beeswax and turpentine. It is commonly used for paper coatings in the United States. In its purest form, it was often used on speedboat hulls in the early 1960s to enhance speed and handling in saltwater. It is also the main ingredient in surfboard wax, combined with coconut oil. Because of its hypoallergenic and emollient properties as well as its gloss, carnauba wax is used as a thickener in cosmetics such as lipstick, eyeliner, mascara, eye shadow, foundation, deodorant, and skincare and sun care preparations. It is also used to make cutler's resin. It is the finish of choice for most briar tobacco smoking pipes, as it produces a high gloss when buffed that dulls with time, rather than flaking off like most other finishes.
