AKA Brazil wax, carnauba is the toughest of all vegetable waxes used in beauty products. It can thicken formulas, give them a solid form (think lipstick), and keep emulsions of oil and water from separating together so they can retain a smooth, uniform texture. Carnauba is often paired with beeswax to give products a shiny, glossy finish, which is essential for formulas such as lip balm and hair pomade to restore moisture and boost shine. Because carnauba is soft and pliable when heated and hard at room temperature, it’s a popular ingredient for waxing kits.
