Carnauba, also called Brazil wax and palm wax, is a wax of the leaves of the palm, Copernicia prunifera, a plant native to and grown only in the northeastern Brazilian states of Piauí, Ceará, and Rio Grande do Norte.
Carnauba is known as the "queen of waxes" and usually comes in the form of hard yellow-brown flakes.
Carnauba is obtained from the leaves of the carnauba palm by collecting them, beating them to loosen the wax, then refining and bleaching the wax.
Carnauba wax can produce a glossy finish and as such is used in automobile waxes, shoe polishes, food products such as sweets, instrument polishes, and floor and furniture waxes and polishes, especially when mixed with beeswax and with turpentine. It is used as a coating on dental floss.
Use for paper coatings is the most common application in the United States. It is the main ingredient in surfboard wax, combined with coconut oil.
