Carnauba Wax is a 100% natural vegetable, vegan wax from the leaves of the Brazilian 'tree of life', carnauba palm, and consists mostly of esters, free long chain fatty alcohols, and free fatty acids & resins.
Commonly used in many cosmetic formulations, particularly stick formulations, Carnauba Wax can impart surface gloss, hardness, consistency and ease of application. It can be used in mascaras as a volumizing agent, in water and oil emulsions as a stabilizer and viscosity modifier, allowing liquids to bind together with other chemical ingredients,
Comes in hard, yellow-brownish flakes. The melting point of carnauba wax (82 to 86 degrees C) is higher than bees wax typically (62 to 64 degrees C). As such you need to use a higher temperate to get it to melt and emulsify. Being a harder wax, you also need less of it in a recipe, if substituting for bees wax, to get the same result.
