Description
A greenish-white vegetable wax that covers the berries of small myrtle bushes, such as Myrica cerifera, native to America, Europe, and Africa. Bayberry wax, or myrtle wax, is collected by boiling the berries in water. It contains myristic acid (58%), Palmitic acid (36%) and Oleic acid (1.3%). Bayberry wax is used for soapmaking, candlemaking, and buffing metals. It has a balsam-like odor and has been used as a natural insect repellent. The tannins from the bark extracts were used medicinally.
