Carnauba wax
Transfer 100 mg of the sample into a test tube, and add 20 ml of n-butanol. Immerse the test tube in boiling water, and shake the mixture gently until the sample dissolves completely. Transfer the test tube to a beaker of water at 60 o, and allow the water to cool to room temperature. A loose mass of fine, needle-like crystals separates from a clear mother liquor. Under the microscope, the crystals appear as loose needles or stellate clusters, and no amorphous masses are observed, indicating the absence of carnaúba wax.
