Beeswax (Cera alba) is a natural wax produced by honey bees of the genus Apis. The wax is formed into "scales" by eight wax-producing glands in the abdominal segments 4 through 7 of worker bees, who discard it in or at the hive. The hive workers collect and use it to form cells for honey-storage and larval and pupal protection within the beehive. Chemically, beeswax consists mainly of esters of fatty acids and various long-chain alcohols.
