![]() These films are resistant to solvent etching by chloroform, toluene, acetone, and alcohols. It provides glossy and slippery surfaces.Ĭarnauba wax can form solvent resistant superhydrophobic films from selfemulsifying mixtures with alcohol emulsions. It also raises the melting point of gels, thus making it the preferred additives in lipsticks, lip balms, and mascara. On its own, it is a brittle wax, hence it is typically combined with other waxes, primarily beeswax, in formulations.Ĭarnauba wax has various applications and uses and these include food, cosmetics, automobile and furniture wax, molds for semiconductors devices, and as coating for dental floss.Ĭarnauba wax has very good emulsification properties and excellent oil-binding capacity for ester oils and mineral oils. Due to its high melt point, it can help to harden otherwise too-soft lip and body balms. It is about 20% esterified fatty diols, 10% methoxylated or hydroxylated cinnamic acid, and 6% hydroxylated fatty acids.Ĭarnauba Wax is both hypoallergenic and emollient, making it well suited to many cosmetic formulations where thickening as well as gloss are required. It might be more accurate to say that many car polishes and candies smell like carnauba wax.Ĭarnauba wax consists of fatty acid esters (80-85%), fatty alcohols (10-16%), acids (3-6%), and hydrocarbons (1-3%). It is one of the highly beneficial natural chemicals and renewable resources with no synthetic equivalents. You use products containing carnauba wax every day, but you may not know what the ingredient is or where it came from. The combination of properties leads to many applications such as coatings for food, cosmetics, automobile and furniture polish, molds for semiconductor devices, and dental floss. ![]() It is harder than concrete and almost insoluble in water and ethanol. It is one of these extremely useful natural chemical and renewable resources that has no synthetic equivalent.Ĭarnauba wax has a very high melting point of 82-86☌ (180-187☏). If what is known is the substance or where it came from, the combination of properties may not lead to a multitude of applications, including use in food, cosmetics, automobile and furniture wax, molds for semiconductor devices, we use products containing carnauba wax every day. Concrete is harder and nearly insoluble in water and ethanol. Although it has been replaced in many applications by cheaper synthetics, it is still used as a polish for candies and medicinal pills, as a thickener for solvents and oils, and even as a hardener for printing inks.Ĭarnauba wax has a very high melting point of 82-86 ☌ (180-187 ☏). It has a melting point of about 85° C (185° F). The wax consists primarily of esters of long-chain alcohols and acids. The final product is yellow or brownish green, depending on the age of the leaves and the quality of processing. The powdery wax is removed (by beating the shriveled leaves), then melted, strained, and cooled. The leaves are cut from September to March and left in the sun to dry. During the regular dry seasons in 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. It has a dense, large crown of round, light green leaves.Īlthough it has been planted in Sri Lanka and Africa, as well as other parts of South America, only in northern Brazil does the tree produce wax. After 50 years, the tree can attain a height of over 14 metres (45 feet). The carnauba tree is a fan palm of the northeastern Brazilian savannas, where it is called the “tree of life” for its many useful products. ![]() Valued among the natural waxes for its hardness and high melting temperature, carnauba wax is employed as a food-grade polish and as a hardening or gelling agent in a number of products. It is obtained from the leaves of the carnauba palm by collecting and drying them, beating them to loosen the wax, and then refining and bleaching the wax.As a food additive, its E number is E903.Ĭarnauba wax, also called Brazil wax or ceara wax, a vegetable wax obtained from the fronds of the carnauba tree (Copernicia cerifera) of Brazil. Carnauba, 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 Pernambuco, Piauí, Ceará, Maranhão, Bahia, and Rio Grande do Norte. It is known as "queen of waxes" and in its pure state, usually comes in the form of hard yellow-brown flakes.
