Audited Supplier Carnauba wax, vegetable wax obtained from the fronds of the carnauba palm (Copernicia prunifera) of Brazil. Valued among the natural waxes for its hardness and high melting temperature, carnauba wax is employed as a vegan food-grade polish and as a hardening or gelling agent in a number of products. Although it has been replaced in many applications by cheaper synthetics, it is still common as a component of certain furniture, leather, car, and shoe polishes and is used in cosmetics such as lipsticks. It is also used as a polish for candies and medicinal pills, as a thickener for solvents and oils, and as a hardener for printing inks.
The carnauba palm is a fan palm of the northeastern Brazilian savannas, where it is called the "tree of life" for its many useful products. After 50 years, the tree can attain a height of over 14 metres (45 feet). It has a dense, large crown of round, light green leaves. During the regular dry seasons in northern Brazil, the carnauba palm protects its metre-long (three-foot) fronds from loss of moisture by secreting a coat of carnauba wax on the upper and lower leaf surfaces. The leaves are cut from September to March and left in the sun to dry. The powdery wax is removed by beating the shriveled leaves, then melted, strained, and cooled. The final product is yellow or brownish green, depending on the age of the leaves and the quality of processing.
The wax consists primarily of esters of long-chain alcohols and acids. It has a melting point of about 85 °C (185 °F).
